Sikasil GP
Sikasil GP is a general-purpose, one-component, non-sag, acetoxy-cure RTV silicone sealant for sealing and bonding windows, storefronts, HVAC, roofing, marine, and appliance work. This Bronze 10 oz cartridge skins in approximately 13 minutes, cures to Shore A 20 with approximately 220 psi tensile and 500% elongation, and applies from 41 to 104 F. It holds elastomeric properties to 350 F continuous (392 F intermittent), bonds many substrates without priming, and includes an anti-microbial additive for mold resistance.

Frequently Asked Questions
What service temperature does Sikasil GP hold?
Permanent service from -76 to 350 F, with intermittent exposure to 392 F while keeping elastomeric properties.
What skin time should crews plan for with Sikasil GP?
Skin time is approximately 13 minutes at 73 F and 50% R.H. Cooler, drier air slows moisture cure.
What substrates does Sikasil GP bond without primer?
Glass, tile, fiberglass, plastic, ceramic, wood, and painted metals are typical. Confirm adhesion on the project substrates.
What hardness and elongation does cured Sikasil GP reach?
Shore A 20 with approximately 220 psi tensile strength and 500% elongation at break.
What paint window applies over Sikasil GP?
It cannot be overpainted. Choose a matching silicone color instead of coating the bead.
