CHT Group TuffGel 331 High Strength Silicone Gel
Categories:	Polymer; Thermoset; Silicone
Material Notes:	Product Description: TufGel 331 is a blue-tinted, tough, moderately cross-linked silicone elastomer, which has good room temperature cure adhesion to many substrates. This material also has enhanced flame retardant properties compared to standard gels. Silicone gels are used to provide protection from vibration and thermal or mechanical shock. Silicone gels also provide excellent moisture protection. Key Features: One to one mix ratio Enhanced flame retardant properties Dispensing equipment not necessary Good adhesion to many substrates including glass, aluminum and copper with primer Formerly Amber Chemical Co (ACC Silicones), aquired by CHT in 2017
