CHILDERS CP-9 AK-CRYL MASTIC COATING
(WATER  BASED)

DESCRIPTION:
Childers AK-CRYL CP-9 is a polymeric, water based weather barrier, breather type mastic. CP-9 dries to a tough flexible film that protects thermal insulation from the ravages of weather by preventing water, rain, snow, sleet, spillage, wash water, etc., from entering into the system. In addition, CP-9 provides protection from mechanical damage created by external forces such as impact abrasion as well as the internal forces of thermal expansion, contraction, or vibration.  Using CP-9 can also protect the insulation from chemical attack of acids, alkalis and solvents. CP-9 is fire resistant and U.V. stable.

USES:
Childers AK-CRYL CP-9 Weather Barrier Coating provides weatherproofing and mechanical protection of thermal insulation both outdoors and indoors, in hot, cold and dual-temperature service. Because it is a ‘breather’ 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, or where a complete vapor barrier system is applied to the insulated surface either before or after the coating is applied.

COLOR:
White

SERVICE TEMPERATURE RANGE:
-40ºF to 180ºF

APPLICATION TEMPERATURE RANGE:
40ºF to 100ºF

DRYING TIME:
Touch - 2-4 hours
Through - 24-36 hours

COVERAGE:

CLEAN-UP:
Warm, soapy water (wet), xylol (dry)

WATER VAPOR PERMEANCE ASTM E-96
Greater than 1.0 perms (Procedure B) at 1/16” film thickness.



CHILDERS CP-10 VI-CRYL MASTIC COATING
(Trowel Grade)

DESCRIPTION:
Childers 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 and insulating cements. It is very thixotropic - it looks heavy but spreads easily. It is available in a variety of standard and special faderesistant colors. 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 lowtemperature, or dual-temperature service when the insulations themselves are vapor barriers. 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. Industry experience has demonstrated that all weather barrier coatings may blister when applied over polystyrene board. This effect may be limited by the use of white colored coatings. VI-CRYL CP-10 weather barrier coating in its Metallic Gray color is the ideal companion product to Aluminum and Stainless Steel Jacketing.

CHILDERS CP-11 VI-CRYL MASTIC COATING
(Brush Grade)

DESCRIPTION:
Childers' VI-CRYL CP-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 and special fade resistant colors. It is outdoor rated and U.V. resistant.

CHILDERS CP-22 / CP-24 CHIL-PRUF
ASPHALT BASED FIBRATED CUTBACK VAPOR BARRIER AND WEATHER BARRIER INSULATION COATING

DESCRIPTION:
Childers CHIL-PRUF CP-22/24 is an effective asphalt based cutback fibrated vapor barrier coating for use over insulations on piping and equipment operating at low to moderately high temperatures. Properly applied, CHIL-PRUF vapor barrier coating provides protection against atmospheric corrosives, chemical dusts, fumes, fogs, and moisture. The cured coating forms a highly impermeable, tough, durable, and well-bonded finish.

USES:
Childers CHIL-PRUF CP-22/24 vapor barrier coating has a broad application range as a vapor and weather barrier over many types of insulations, including fibrous glass, polyurethane foams, glass foams, and other low temperature insulation materials. It is not to be used with polystyrene foam insulation. CHIL-PRUF vapor barrier coating is recommended for use in cold and dual temperature service. As a vapor barrier coating, it is used to protect insulation over fittings, piping, tanks and tank heads, process vessels, and equipment. CHIL-PRUF vapor barrier coating also provides protection for insulation applied on underground pipelines.

CHILDERS CP-25 CHIL-BRATE
WATER BASED FIBRATED ASPHALT EMULSION WEATHER BARRIER
INSULATION COATING

DESCRIPTION:
Childers CHIL-BRATE CP-25 is a water based fire retardant fibrated asphalt emulsion weather barrier coating for use over insulations on above ground installations operating at moderate to high temperature service.  Since it is a “breathing” coating, vapors under pressure will pass through it. When dry, the film is tough and durable. It provides protection against atmospheric corrosives, chemical liquids, and fumes.

USES:
Childers CHIL-BRATE CP-25 weather barrier coating is primarily designed to protect insulation on equipment and structures in high temperature service, although it also provides protection against corrosion when applied directly over steel and concrete. Typical insulations protected with CHIL-BRATE weather barrier coating include calcium silicate, mineral and glass fibers, polyurethane, and foamglas.

CHILDERS CP-30 CHIL-PERM LO
LOW ODER VAPOR BARRIER COATING FOR INDOOR APPLICATIONS

DESCRIPTION:
Childers CHIL-PERM CP-30 LO is an extremely effective vapor barrier coating for all low temperature applications. In the wet state, it has an unusual consistency which allows it to be buttered-on in relatively heavy films, or it can be brushed out into thin films. It is made with an elastomeric resin which yields a tough, yet flexible, dry film with excellent adhesive properties.

USES:
Childers CHIL-PERM CP-30 LO Vapor Barrier Coating, in the dry state, is a fire resistive, flexible coating for all types of thermal insulations in cold and dual temperature service. As an indoor vapor barrier coating, it is used to vapor seal fittings, piping, and equipment insulated with fibrous glass, polyurethane foams, and other low temperature insulation materials. It is not to be used in direct contact with polystyrene foams. CP-30 LO coating is used as a barrier at the butt joints of pipe and block insulation where intermediate vapor stops are required. CP-30 LO coating is also used to seal the joints of foil-faced boards and other factory vapor sealed insulation material, and also where pins and staples puncture insulation vapor barrier facings.

CHILDERS CP-35 CHIL-PERM WB
INDOOR & OUTDOOR WATER BASED VAPOR RETARDER COATING

DESCRIPTION:
Childers CHIL-PERM WB CP-35 is an effective, high performance, water based, vapor retarder coating designed for all interior and exterior, low temperature and some dual temperature applications. It is fast drying and forms a tough, flexible dry film which retards the flow of vapor through an insulation system. It looks heavy, but  spreads easily. It can be applied in a relatively heavy film or brushed out into a thin, smooth film.

USES:
