Liquid rubber and other moulding and casting resources

I’ve come across some interesting sites to do with making in the last few days.

Smooth-On: These people produce liquid rubbers and plastics for artists and industry: silicone rubbers, urethane rubbers, liquid plastics, foams and so on. They offer detailed product and technical information, and their How to step-by-step turorials on various ways of moulding and casting look great.

Rowe Trading Company: The Australian distributers for Smooth-On, based in Adelaide. I notice that Rowe are also distributers for Bondmaster adhesives. Most of us who make foam puppets are used to using Gel Grip, or a similar type of contact glue to join foam pieces. Its smelly, you have to take care with the fumes, and it takes a few minutes to go tacky before you can press the two surfaces together. Bondmaster produces a much friendlier two-part glue which consists of a pinkish dab-on liquid, and a spray-on catalyst. It bonds foam immediately, has no smell to speak of, and is easier to get into deep places, and onto fabric. In a few circumstances though, say when seams are under pressure, I still opt to use Gel Grip. And the last I heard, Bondmaster is hard to buy except in industrial quantities.

Barnes Products: I’ve heard good things about this Sydney moulding and casting supplier. Their catalogue is online, and they have a range of videos and books on moulding and casting.

Activa products: Activa make an interesting air-dry casting compound called LI-QUA-CHÉ, which is a recycled paper fibre polymer based compound. Its looks like clay slip, and dries to a hard durable glossy satin finish.
