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.

Long Potlife PU Resin
Monday, 12 June 2017  | 

I've used many PU resins from various sources over the years but this is now my favourite. The addition few minutes on the potlife allow for thorough mixing, with plenty of time for most pours that need the mold tilted, tapped etc. When cured it is strong, easy to sand and work with. A pleasant ivory colour, easy to paint, highly recommended.
