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.
