Product Details:

Excellent Adhesion to a Variety of Clean Surfaces
Superior Exterior Weathering Properties
Easy to Apply and Tool 

CRL 777 Butyl Rubber is a unique, butyl-based sealant specially formulated using a blend of age resistant polymers to give excellent weathering properties at various temperature extremes. CRL 777 offers excellent adhesion to most clean surfaces, and will withstand joint movement of ±10% without affecting its water-tightness. It also has a special Ultra Violet fighting agent for exceptional service life. Recommended for exterior applications, CRL 777 Butyl Rubber Sealant features excellent adhesion to wood, masonry, glass and metal surfaces. Hidden areas, such as under sill cans, thresholds, and around screw heads are excellent applications. Other areas, such as between metal building panels, wall-mounted air conditioning units, under aluminum siding and gutters are all good application for proven butyl sealants. Application temperature range is 0 to 120 degrees Fahrenheit (-18 to 49 degrees Celsius). Service temperature range is -20 to 200 degrees Fahrenheit (-29 to 93 degrees Celsius). Paint time is 24 hours.

In order to help you better select the correct sealant, we have put together a Silicone and Sealant Selector Chart.
