Henkel Loctite® Stycast® 2651MM with CAT 11 Two-Component General Purpose Encapsulant
Categories:	Polymer; Adhesive; Thermoset; Epoxy; Epoxy Encapsulant, Unreinforced
Material Notes:	Designed as a general purpose encapsulant which requires low viscosity and low abrasion. It is especially useful for machine dispensing and for parts that require post molding machining. 2651MM is a filled, low viscosity, general purpose, epoxy encapsulant. It contains a soft filler that both reduces abrasion in meter/mix equipment and enhances machinability in the cured product. Property data reported for 2651MM with CAT 11 Catalyst. Good Chemical Resistance Filled High temperature Thermally conductive Mix Ratio by Weight = 100:8.5 Cure Type: Heat
