SRC Model-Pro Off White 1 Gallon, Polyurethane Casting Resin

This was my first time working with a urethane resin, had a project that required 2 dozen replicas of 6" sculpture. Took some testing to get a feel for this material but I eventually dialed it in. Here are my takeaways: -Material sets and hardens extremely quickly. At 78F in my shop my total working time was under 90 seconds. I needed more time so I refrigerated the two parts to roughly 45F and this gave me roughly 3.5 minutes. I was able to demold the castings in about 10-12 minutes, my production went quick with this aspect -This material is certainly not bubble free, at least in a closed mold with tough geometry. A pressure pot was needed - this worked excellently but I had to be extremely quick to get it mixed, poured, and pressurized. (chilling the resin was necessary for enough time) -It is relatively exothermic, it gets quite hot when setting. -I did not experience any brittleness or lack of hardening with the two separate kits I purchased. It does seem relatively forgiving with mixing. -The as-cast material has a very nice feel to it and accurately reproduced all the details from my mold. It can be sanded reasonably well (with dust extraction!) My client was extremely pleased. I wouldn't hesitate to purchase this again.

I love this resin it cures super fast. It looks like ceramic it dries off white with shine. Reminds me of ceramic. Will buy again

Very pleased so far. Truth will come once I build a antler with it.

High quality, water like viscosity. Quick cure time with nice finish.

This material works very fast and is a nice solid off white, it can be a little brittle but it's worth getting for a nice white finish that is perfect for painting.

Good product and shows great detail

Great product easy to use perfect casting wiil buy again. Thanks

my favorite resin for my dogs and horse casting. Resin castings hand painted.
