I am gluing black pvc sheet - I presume its pvc, although not 100% certain, it has that distinctive 'new beach ball' smell to it. I'm prototyping right now, and I want to do more stuff like this - and will likely post an instructable - trouble is it walks a fine line of 'family friendly'/sfw. Either way; I used Lepage Flexible Plastic adhesive. It worked quite well, and has proven to be quite strong and flexible so far...Works like a contact cement, but stays very flexible. No mention on the packaging exactly what type of glue it is though. My question: What type of glue is this? Characteristic acetone volatile smell, works like contact cement. Package says apply, let dry to touch ~10-30 minutes then close surfaces. I find it's dry to the touch within a minute or three. (extremely dry climate + warm room I was working in). Rationale: It's expensive, 4 bucks for 30mL, and I'd rather have a can-container to dip a brush in. At the hardware store they have plain-ol contact cement, but the transparent/flexible aspect of this is must. Thanks in advance!
