Childers CP-10 Mastic

DESCRIPTION VI-CRYL® CP-10/11 weather barrier coating is a tough, durable and fire-resistive, water-based mastic for most types of thermal insulation and finishing and insulating cements. It is very thixotropic – it looks heavy, but spreads easily. It is available in a variety of standard colors. It is outdoor-rated and U.V. resistant. USES VI-CRYL® CP-10/11 weather barrier coating is unsurpassed for the mechanical protection and weatherproofing of thermal insulation both outdoors and indoors in hot, cold and dual-temperature service. However, since it is a ‘breather’ coating (vapors under pressure will pass through it), it should only be used over insulations in lowtemperature or dual-temperature service when the insulations themselves are vapor barriers. VI-CRYL® CP-10/11 has also found use throughout the thermal insulation industry as a coating used over closed cell polyethylene and polyurethane foam insulation. Industry experience has demonstrated that all weather barrier coatings may blister when applied over polystyrene board, but may be limited by use of white colored coatings. VI-CRYL® CP-10/11 weather barrier coating in its metallic gray color is the ideal companion product to aluminum and stainless steel jacketing. APPLICATION VI-CRYL® CP-10/11 is easy to apply by trowel, brush or heavy-duty airless spray. Its thixotropic consistency yields a smooth, attractive finish even over rough substrates; it readily fills gaps and imperfections. CP-10/11 coating should be applied with glass fiber or synthetic reinforcing mesh. ADVANTAGES • In the wet state, VI-CRYL® CP-10/11 weather barrier coating is non-flammable. It contains no solvents that will attack insulations or facings. • The cured film is tough, flexible and resists most common chemicals and many solvents. • Fire-resistive: its flame spread index being within the range of acceptance of government and industrial agencies.
