Here is a quick look into the urethane casting process from beginning to end. In this video we show how cast urethane parts are produced in a open cast process.
I know its a long shot but it seems the more i try to research into what blends of ingredients companies use for this stuff the mote i see people saying thay they are heavily secretive recipies. I wish there was an open source list of ingredients for people who dont have a chemistry degree like me. I understand people cant tell you proprietary formulas but if there was a list of ingredients with general descriptions and no specific ratios that woulf be so helpfull for what people like me are trying to do in their garages.
We would suggest opening up your search to raw material providers, they may be more willing to go over specifics. If you haven't seen them yet, look at these videos. They may provide some general knowledge for you on this search. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jluzvlSa7FM.htmlsi=7KJkv3ZoNUqjsJvM ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WSUJoeXzOHY.htmlsi=dKb2ryAjm0Brv8hX
