DESCRIPTION: VI-CRYL CP-10 weather barrier coating is a tough, durable, and fire-resistive water based mastic for most types of thermal insulation and finishing/insulating cements. It is very thixotropic - it looks heavy but spreads easily. It is outdoor rated and U.V. resistant.
USES: VI-CRYL CP-10 weather barrier coating 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). VI-CRYL CP-10 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 CP-11 to seal up all exposed fiberglass, paint any tape seams and SSL closures to prevent condensation buildup on the pipes.
* CP-11 can be painted on with a brush while CP-10 is applied with a trowel
