Polycraft SG2000 fast cast resin is an odourless two component polyurethane system which is designed for rapid demould times.
Polycraft SG2000 can be used in prototyping and model-making areas.
Applications include : Patterns, Negatives, Castings, Models, Vacuum forming tools, prototypes etc.

Each kit will come with the same weight in each container, but part A comes with a filler powder additive, therefore increases the volume, both part A and B are different volumes, therefore the resin must be measured by equal weights, shake well before use.
Before use, be sure that Parts A and B are at room temperature and tools and moulds or models are ready to go. Surfaces and air temperature should be above 60°F during application and for the entire curing period. Use metal or plastic mixing vessels and spatulas to avoid introducing moisture (i.e.., with paper or wood tools).
Measure equal weights of part A and part B into a mixing container such as a polyethylene pail. Mix immediately, thoroughly scraping sides and bottom for one minute. Pour mix into mould cavity. Once the containers of Parts A and B are opened, they should be used or resealed tightly as atmospheric moisture contamination may cause foaming of the plastic.
This polyurethane system is recommended over polytek polyurethane if you plan to paint your cast part, plastic primer base coat is advised.
