    Basic Uses
    Recommended for exterior applications, CRL 777 Butyl Rubber Sealant features excellent adhesion to wood, masonry, glass, concrete, some plastics, 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 applications for proven butyl sealants. Application temperature range is 40° to 120°F (4° to 49°C). Service temperature range is - 20° to 200°F (-29° to 93°C). Paint time is 24 hours.

    Limitations
    Not recommended for use in sealing horizontal decks, patios, driveways or terrace joints where abrasion or physical abuse is encountered. Not recommended for use in window glazing applications or hidden joint details, which require a non-skinning, non-hardening sealant. CRL 777 has a solvent based curing system. A slight odor of mineral spirits will be detected during application, which is normal. Do not use where this odor may be objectionable, such as refrigeration units that will be stocked soon after construction. Check cartridge label and Specification Data Sheet for additional limitations. NOTE: All colors are available in bulk packaging.
