We are always offering new products on our website including this polyurethane resin casting material called ProtoCast. I used it this morning and had great results. The color is a bright white and the surface of my cast is very smooth.
I mixed Component A and Component B by volume which means you can mix it 1:1. You can also mix it by weight which is 100 parts Component A to 86 parts Component B. Easy! I waited 20 minutes and it had cured perfectly at room temperature.
Note: If you are making a large cast, I would recommend cooling the mold in the freezer (or wrapping a larger mold in ice packs) once you pour the ProtoCast. This will slow down the curing process which produces heat that could compromise the integrity of your mold.
Keep checking back to our website to see what kind of new products we've added. And never hesitate to let us know what else you might need for your molding and casting projects.
