DOWSIL™ 888 Silicone Joint Sealant is one-part, non-sag silicone material that cures to a low-modulus silicone rubber upon exposure to atmospheric moisture. Can be applied over a wide temperature range.

Benefits:

Can be extruded from -20 to 120°F.
May be used in joints that are not uniform in width.
Movement capability 100% extension and 50% compression.
Low modulus.
Weather and UV resistant.
Fuel resistant-short term exposure. Refer to Dow form number 62-207 for more information.
One component, cold applied, ready-to-use as supplied; dispensed directly from the bulk container into the joint by hand or with an air-powered pump.
Unprimed adhesion - primer is not required for bonding to Portland cement concrete. For optimum adhesion, the surface must be clean, dry and frost-free.
Cure time - typically, the sealant will have a skin-over time of one hour or less at standard conditions.
