Vac Master 25 is the ideal urethane for abrasion resistance and durability – it has good physical properties and low shrink.

I use VM25 to reproduce soft plastic lures, I can’t say enough positive things about this product, it picks up every detail and so far no breakdown or breakage of the molds, if you try this product don’t forget to use their mold release, it’s a must. Glad I found Alumilite!
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. God bless! Skip
