Material Notes:
QSil 40 is a general purpose two-part, room temperature, condensation cure siloxane elastomer. The two applicable catalysts are 0.5% DBT by weight and 10% Deep Section Catalyst by weight. Cure speed can be accelerated by adding DBT catalyst in increments of 0.1%. This will not alter the physical properties of the material. QSil 40 exhibits excellent release properties. However, strong adhesion can be achieved through the use of a primer. Key Features: Good adhesion with use of a primer Self-leveling Variable cure speedPart of the Amber Chemical Group.
