CHT Group QSil 940 QSI Quantum Silicones 40 Durometer Condensation Cure for Potting
Categories:	Polymer; Thermoset; Silicone
Material Notes:	QSil 940 is a special purpose, two-component condensation cure siloxane elastomer that exhibits excellent release properties unless a primer is used which results in excellent adhesion. The material can also be used for applications that have wide temperature range requirements. The two applicable catalysts are 0.5% DBT by weight and 10% Deep Section Catalyst by weight which gives a work life of approximately 45 minutes and a tack free time of 2 hours. The 0.5% catalyst level can be increased or decreased to obtain desired cure speed. Cure speed can be accelerated by adding DBT catalyst in increments of 0.1%. Key Features: Excellent release properties unless a primer is used Variable cure speed Part of the Amber Chemical Group. Data provided by manufacturer. Formerly Amber Chemical Co (ACC Silicones), aquired by CHT in 2017
