Material Notes:
Resinlab™ EP1200LV a low viscosity version of EP1200, a highly filled, medium viscosity black casting resin designed for applications requiring a high degree of thermal conductivity, flexibility and a low CTE. It meets the requirements of UL Standard 94 for a horizontal burn rating at 1/4" thickness. It was especially formulated to a 1:1 mix ratio for use in MMD equipment or side-by side cartridges. It contains abrasive aluminum oxide filler which can introduce 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 2 hours at 65oC for ease of processing and also to reduce viscosity. It was especially formulated to a 1A:1B volume mix ratio for use in side-by-side dispensing cartridges and meter/mix and dispense equipment. Times and temperatures from 2 hours at 65oC to 10 minutes at 100oC are typical for small castings (less than 100 grams).Information Provided by Resinlab L.L.C., an Ellsworth Adhesives Company.
