Processing & Fabrication

Thoroughly mix Part A and Part B in a 100:1 ratio. Avoid introducing bubbles. For critical applications, de-air mix under vacuum. The pot-life is 24 hours at 25°C. Avoid entrapping air during transfer and casting. Cure at 100°C for 8 hours or at room temperature for 72 hours. Silicone Elastomers C can be self-bonded by exposure to oxygen plasma and pressing surfaces together in a dry atmosphere.
