Childers® CP-11 VI-CRYL Mastic Coating - White
VI-CRYL CP-11 weather barrier coating is a tough, durable, and fire-resistive water based white thermal mastic for most types of thermal insulation and finishing/insulating cements. It is very thixotropic - it looks heavy but spreads easily. Childers mastic is outdoor rated and U.V. resistant.
USES:VI-CRYL CP-11 thermal mastic paste is unsurpassed for the mechanical protection and weatherproofing of thermal insulations both outdoors and indoors, in hot, cold, and dual-temperature service. However, since it is a ‘breathing’ coating (vapors under pressure will pass through it) it should only be used over insulations in low temperature, or dual-temperature service when the insulations themselves are vapor barriers (Fiberglass Pipe's ASJ paper is a vapor barrier). Childers CP-11
Thermal Mastic compound has also found use throughout the thermal insulation industry as a coating used over closed cell polyethylene and polyurethane foam insulations. Note from Buy Insulation Products - CP-11 and CP-10 are great for sealing up insulation on chilled water systems. Use Childers CP-11 White Mastic to seal up all exposed fiberglass, paint any tape seams and SSL closures to prevent condensation buildup on the pipes. CP-11 white thermal mastic paste can be painted on with a chip brush.
APPLICATION
VI-CRYL CP-11 weather barrier coating is easy to apply by Brush or Heavy-Duty Airless Spray. Its thixotropic consistency yields a smooth, attractive finish even over rough substrates; it readily fills gaps and imperfections. VI-CRYL CP-11 coating should be applied with glass fiber reinforcing mesh.
ADVANTAGES
In the wet state, VI-CRYL CP-11 weather barrier coatings 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.
It is fire-resistive: its flame spread index being within the range of acceptance of government and industrial agencies.
