Tired of emptying your pockets to have your photos mounted and framed? The quality, expense and lack of variety at most framing shops is pretty frustrating. Not only that, putting yourself at the mercy of a someone else's schedule when you're in a hurry to hang or install a show is stressful. Take matters into your own hands and polish off work by casting photos in crystal clear, UV protective epoxy resin. Casting photos in resin is fool-proof and an easy solution to protecting your work while minimizing distractions from the surface of your pieces. This step-by-step tutorial will address how to construct a clean wooden surface to mount your images, seal them, and cast them in resin. It’s easier than you probably expect and the results are stunning.

The main ingredient for this project is EX-74. There're dozens of epoxy and polyester resins on the market, but in my experience EX-74's the safest to handle and it stands the test of time preserving it's glasslike sheen. It's a two part mixture; one part resin and an equal part hardener. One quart is about the amount I'd suggest using to cover a 15x15" surface; .5 qts resin + .5 qts hardener =15x15" piece. Let this be your base number in determining how many quarts you will need to cast your piece. EX-74's available by the gallon at TAP Plastics or the manufacturer's website eti-usa.com.

Additional supplies: workable fixative, respirator, rubber gloves, heat gun, 2 calibrated gallon buckets, stir-stick, wood patch, spackle spreader, wood glue, acrylic gel medium, exacto or razor, pine struts ~.5"x1.5”, 1/4” mdf slab, tape measure, foam roller, primer, paint brush. Power tools included a table saw, chop saw, belt sander, and nail-gun.

You've done a very good job of clearly explaining the process. I've not worked with resin before. Is this something middle school students could do if there were enough parent volunteers on hand?

Speaking from my own experience, I wouldn't try it. Resin can be hard enough to keep contained to your work area when there's no other hands involved. It sticks to everything and will ruin clothes in an instant.

...and I was wondering about the smell. There are probably rules about having a hood to take care of the gassing. Somebody would probably show up in their $150.00 Nikes...Thanks.

Smell in this case means toxic chemicals - some one needs to look at the material safety data sheet (MSDS) which I have not the time to do right now - or even read carefully the back of the can. When it says breathing may cause central nervous system damage (brain nerves) and even death - it means it. I see these suggestions all over youtube now and it is scary no one seems to take the warnings seriously. (often)

Resin does not release any significant amount of fumes because it is not solvent based. Inhalation is not a big concern with resin. The only health concern in using it is if it is improperly cleaned up using acetone. Acetone should never be used around resins because it can carry them through the skin and into the bloodstream.

NightHakinLight I beg highly to differ and can with 3 degrees (biochemistry, arts/chemistry of arts and health fields) (remember the artist Eva Hess - dead from working with epoxy resins) point you to the proper literature. "resin is not solvent based" (yes it is!) Some are already mixed into the product ie reason why it is liquid, or if it comes in powder form (industrial) it is added later. But I can assure you the solvent is there or it would not be well solvent! (liquid). When they are combined as in a "two part" resin (and there are many types) epoxy being ONE version of many, the combinations causes an exothermic (heat) reaction and it "cures".

2 - remember many toxic chemicals have no odor (CO for one). You may have meant non petro solvent based as all products have a solvent even if it is water. Acetone is as well toxic. As well the two part (or even single) glues are forms (variations of formula's) of epoxy - some need to be heat/reassure cured (industrial) and some two part "curing". All are exothermic.

As well the limbic system of the brain is the main entry point for "fumes" (gases). Not just the skin. I have known many artists/people on Canal street in NYC who died (one owner of epoxy resin shop that made fiber glass - the filler, products, ie bird baths so on). All are in the same class but may have a different trade name - you can look up the OSHA chemical reference book as well.

I have an extensive background in plastics (epoxies are classed under this class) as I used to work with them (but again wore and did proper procedures to protect myself).

Note below - the finished product says "almost non - toxic" not completely inert - big difference if one uses them a lot over time.

As well this review was for a manufacturer... note near the end "loss of consciousness" and this does not include long term over time repeated exposures.

There is as well much literature (scientific, lab our board, medical) on the exact mechanism whereby enzyme, and other systems are damaged by exposure.

If one looks at each of the chemicals listed one can find the damage that can be done, without proper protection.

Now you can add your science to show solvents are not in resins.

I know the end result of being exposed long term to these class of chemicals and just putting out some warning signals. It I can assure you is on the back of the can as well.

Acetone would be listed as a co toxin (when more then one are involved in exposures)... there is safe and safer but all in one form or another are toxic and need proper protection guidelines when used.

..................................

Just some quick searching.

"The hardened, finished polymers are almost non-toxic; it is exposure to the uncured resin components that can be harmful. In a two-component epoxy product, the epoxy resin andthe curing agent are packaged separately and must be mixed together just before being used.

Each component can be hazardous.

In a single-component product, the resin and the curing agent are supplied in a pre-mixed form. Single-component systems are usually safer, because the hazardous chemicals are already partly combined into less toxic polymers and because they do not evaporate into the air as easily.

You Have the Right to Know:

(GISO 5194), your employer must tell you if you are working with any hazardous substances, including epoxies, and must train you to use them safely.

Because different additives to epoxy resin systems can affect your health in different ways, you should find out what chemicals are in the products you use.

Epoxy Resin Systems

Material Safety Data Sheets (MSDSs) for the products in your work area.

An MSDS liststhe hazardous chemical contents of a product, describes its health and safety hazards, and gives methods for its safe use, storage, and disposal. The MSDS should also include information on fire and explosion hazards, reactivity, first aid, and procedures for handling

leaks and spills. Your employer must have an MSDS for any workplace product that contains a hazardous substance, and must make the MSDS available to employees on request.

This Fact Sheet is an aid for worker training programs. It does not take the place of Material Safety Data Sheets. HESIS Fact Sheets are available for several of the chemicals commonly added to epoxy resin systems; see page 6.

Examples of Epoxy Resin System Chemicals

Epoxy Resins

(monomers or oligomers) can be powders, or they can be thick, clear or

yellow liquids. Some common epoxy resins are: the diglycidyl ether of bisphenol A

(DGEBA), novolac resins, cycloaliphatic epoxy resins, brominated resins, epoxidized olefins, Epon R and Epikote R

.

Curing Agents

react with epoxy resin monomers to form epoxy products. They are

usually liquids with strong, unpleasant odors. There are several categories of curing agents. Examples include:

Aliphatic amines

such as triethylenetetramine (TETA) and diethylenetriamine

(DETA);

Aromatic amines

, including diaminodiphenyl sulfone (DDS) and dimethylaniline

(DMA);

Anhydrides

such as phthalic anhydride and nadic methyl anhydride (NMA);

Amine/phenol formaldehydes

such as urea formaldehyde and melamine

formaldehyde;

Catalytic curing agents

such as tertiary amines and boron trifluoride complexes.

Diluents

and solvents are used to dilute or thin epoxy resins. Diluents are usually

clear liquids. Some examples are:

Glycidyl ethers

(reactive diluents) such as n-butyl glycidyl ether (BGE),

isopropyl glycidyl ether (IGE) and phenyl glycidyl ether (PGE);

Organic solvents

such as toluene (toluol), xylene (xylenol), acetone, methyl ethyl

http://www.dhs.ca.gov/ohb/HESIS/epoxy.htm (3 of 9) [5/6/2008 1:35:03 PM]

Epoxy Resin Systems

ketone (MEK), 1,1,1-trichloroethane (TCA), and glycol ethers.

Fillers

add bulk and body to epoxy products. They are usually powders or fibers

such as sand, clay, calcium carbonate, fiberglass, asbestos, or silica.

HOW DO EPOXIES ENTER AND

AFFECT YOUR BODY?

The chemicals in epoxy resin systems can affect your health when they come in contact with your skin, or if they evaporate or form a mist or dust in the air you breathe. The main effects of overexposure are irritation of the eyes, nose, throat, and skin, skin allergies, and

asthma. The solvent additives can cause other effects such as headaches, dizziness, and confusion.

Lungs:

Vapors and spray mists of most epoxy resin system chemicals can irritate your

lungs. Some people develop asthma from the curing agents. Symptoms of asthma include chest tightness, shortness of breath, wheezing, and coughing. These symptoms may occur

after work or at night. Once a person becomes allergic to curing agents, even the dusts from sanding or grinding the hardened plastics can cause an asthma attack.

Skin:

Epoxy resins can cause skin irritation. Symptoms include redness, swelling, flaking,and itching on the hands, face, or other areas of contact. Some people develop a skin allergy or sensitivity to epoxy liquids or mists. Skin allergies may develop after just a few days of contact or after many years of exposure to epoxies. Sensitized skin may become red, inflamed, blistered, and itchy even from brief contact with epoxy resins.

Eyes, Nose, and Throat:

Most epoxy resin system chemicals and their vapors (especially

the curing agents and solvents) can irritate your eyes, nose, and throat. Some people develop headaches as a result of this irritation. If the liquids are splashed into your eye they will sting, and they can severely damage the eye. In case of eye contact, immediately rinse the eyes with water. Continue rinsing for 15 minutes and then seek medical attention.

Nervous System:

Solvents inhaled or absorbed through your skin can affect your central

nervous system (your brain).

Symptoms of solvent

overexposure include headache, nausea, dizziness, slurred speech, confusion, and loss of consciousness. For more information, ask for the HESIS Guide to Industrial Solvents.

sazure,

I appreciate you lending your experiences and information to this discussion, as I think the MSDS and warning labels should be considered by all who are looking to pioneer resin casting. I also work with epoxies at my day job and am well aware of the hazards if not handled properly. While there are many different resins on the market and their chemistry/warning labels might differ, I'll certainly advocate playing it safe and wearing a respirator and gloves in all cases.

NightHawkinLight - to be fair I dug out my 3 inch book on plastics/resins chemistry of and maybe you meant the following (see below). (great book for all would be "artists beware" written by Dr. Michael McCann PhD, CIH (when I was at an end stage he sent me tons of material and to Dr. Ziem specialist in toxity exposures from Vietnam Vets - A truly amazing man.)

(forgive font' know how to shrink font sizes)

"non solvent" and usually for high end industrial use.

Novolac epoxy resin

Reaction of phenols with formaldehyde and subsequent glycidylation
with epichlorohydrin produces epoxidised novolacs, such as epoxy phenol
novolacs (EPN) and epoxy cresol novolacs (ECN). These are highly viscous
to solid resins with typical mean epoxide functionality of around 2 to
6. The high epoxide functionality of these resins forms a highly
crosslinked polymer network displaying high temperature and chemical
resistance, but low flexibility. 100% solids hybrid novolac epoxy resin
systems have been developed that contain no solvents and no volatile or
organic compounds. These hybrid novolac epoxies have been documented to
withstand up to 98% sulfuric acid.



Artist Beware, Updated and Revised: The Hazards in Working with All Art and Craft Materials and the Precautions... by Michael McCann PhD CIH
(Jun 1, 2005)

So you may have meant this "non solvent" but it is so high end ie industrial and I just assumed the project here mentioned meant the typical over the counter can. Who knows.

None the less I am many others ended up nearly dead, or dead due to repeated exposure to these products. I mention this as I did not know prior myself... I learned the very hard way about the toxicity and damage these products due over time to the human (and all other creatures) physiology.

As well the governing bodies meant to protect one such as the EPA, FDA are well behind on the safety of these and other toxic chemicals. Think Bayor Aspirin Bayor Pesticide (Monsanto) and one can only imagine why... Huge influences by manufacturers.

Be well and take precautions is all I meant to say.

BillMil sazure3 months ago

I appreciate your very thorough contribution, sazure. Thnaks!

Kit Vogel (author)  BillMil3 months ago

Definitely get comfortable with it yourself before making it a school project. It's not a matter of having enough hands to have a workshop like that, as much as it's having experience getting the process down.

spunk3 months ago

That's a great idea!

Is the effect of the resin similar to diasec - does it give this brilliant and sharp appearance to the photographs?

Kit Vogel (author)  spunk3 months ago

spunk,

I've never used diasec, but yes it does. As mentioned before, though, it will slightly dull your brights (ever so slightly) due to the refracted light that would otherwise hit the bare surface of your photo. Best to amp up your brights if possible. Best

rmiller213 months ago

Looks great and thanks for sharing. I've been thinking about a project like this for a while now. Couple of questions: could you paint the sides instead of leaving them natural color? I was thinking of a nice, rich black to make the photo pop. What type of paint would you use to produce the best result with the resin?

Kit Vogel (author)  rmiller213 months ago

You can paint the sides if you like. In my experience, any type of paint should work just fine. Good luck

srdumstorf3 months ago

Great ideal. If I could suggest using two mixing containers. Punch a 1/4" hole close to the bottom of one container, place a piece of tape over this hole. Mix your epoxy in the other container than gentilly pour the premixed epoxy into the container with the taped hole. Hold the epoxy container slightly above your work and remove the tape. The air bubbles will rise to the surface allowing the epoxy that comes out of the hole almost free of suspended bubbles.

Have you seen any change in the colour of the photos over time?

all epoxies yellow over time.

Thanks guys!!! nice Vogel!
Kit Vogel (author)  coolmilo3 months ago

coolmilo,

No, photos shouldn't discolor so long as they're sealed. Putting anything over the surface of your photos will dull the whites and brights a hair though, due to the refracted light that would otherwise hit the surface directly. You may want to amp the brights up a touch. The resin, however, will yellow if it's exposed to extreme heat or intense sunlight. Like all plastics, resin becomes more malleable in heat. It's best to keep your pieces in temperate spaces. Good luck!
