Polycraft FC-7450 Fast Cast Polyurethane Backfill Resin System

Applications include : Patterns, Negatives, Castings, Models, Vacuum forming tools, prototypes etc. Due to the low cost of this resin it is ideally suited as a backfill resin, it is also well suited to projects that resin large amounts of fillers to be added to resin.

While this resin is of a high quality, for single pour castings where high detail and strength are required we would recommend other polyurethane resins such as the Easyflo 60, SG2000 or the FC-6000. As always if unsure as to the suitability of the resin for your project please speak with us first and only order the small kit first for testing.

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.
