CHIL-BRATE™CP-25 Weather Barrier Coating
WATER BASED FIBRATED ASPHALT EMULSION WEATHER BARRIER INSULATION COATING
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
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 glass foams. It is not recommended in ponded water areas or over polystyrene foam insulation.APPLICATION
All surfaces must be clean and dry. DO NOT THIN. CHIL-BRATE CP-25 is designed to be applied by trowel. A two-coat application of equal thickness is recommended, with a glass fiber membrane (Chil-Glas® #5 or #10 glass cloth) embedded into the tack coat. Chicken wire should not be used. Total coverage shall be 15 gallons per 100 sq. ft. (6.1 liters/sq.m), 0.12 (3 mm) dry film thickness. Foot or mechanical traffic is NOT recommended for roof or tank top applications where high ambient temperatures may soften the mastic film. Not recommended for indoor use. This product cannot be successfully applied by brush or spray. Outdoor horizontal surfaces must always drain completely. A pitch of at least ½ per foot (4 cm/m) is requiredADVANTAGES
