Vac Master 25 is the ideal urethane for abrasion resistance and durability – it has good physical properties and low shrink.
Prior to using product, please read all Technical Data, Safety Data, and Instruction sheets linked below.
Takes a long time to mix, even with a paint shaker and a paddle mixer. Make sure after mixing you use a strainer on part A and B or you will wind up with a $65.00 paper weight like me. Does drill well and machined well just takes a long time to mix.
I called and asked what product these folks suggested making holster molds from and was told they suggested Vac Master 25. I have never worked with two part urethane before so....this was going to be a first! I had also never made a gun mold before so......it was really going to be a first! haha
Long story short, my molds held up and made some class act holster molds! Great product, wonderful results.
