CAL-685 Silicone primer

Citrine® CAL-685 is a two-part silicone rubber primer for silicone rubber and for vulcanizing silicone on other materials.

The CAL-685 helps unvulcanized platinum-based liquid silicone rubber (LSR) stick to various surfaces, including organic glass, aluminum, bakelite, nylon (PA), polyimide, and epoxy resin during the overmolding process.

Features:

• It serves as an excellent adhesion promoter for bonding silicone to a variety of materials. It works both for initial vulcanization and second vulcanization of silicone material, BPO-vulcanized PSA raw silicone.
• It demonstrates water resistance, alkali and salt mist resistance, chemical resistance, oil resistance, solvent resistance, and durability in harsh and challenging environments.
