Material Notes:
Resinlab™ EP1296 is a highly filled, moderately thixotropic black casting resin designed for applications requiring good thermal conductivity, low shrinkage and a low CTE. It was especially formulated to a 1:1 mix ratio for use in MMD equipment or side-by side cartridges. It contains fillers, which are low in abrasive character to minimize wear considerations for wetted components. It shows very good stability in side-by-side cartridges. Cure is normally achieved at room temperature although an elevated cure schedule can be used to reach final properties quickly. This product was designed to be cured in less than 1 hour at 60°C for ease of processing and also to reduce viscosity. Times and temperatures from 1 hour at 60oC to 15 minutes at 100oC are typical for small castings (less than 50 grams). Heat should be applied after product has gelled.Information Provided by Resinlab L.L.C., an Ellsworth Adhesives Company.
