Applications & Uses

Preparation and Application Information

Insulated Vertical Surfaces

• A two-coat application is recommended; each coat is applied at a coverage rate of 4.85 gal./100 sq. ft. for a total coverage rate of 9.7 gal./100 sq. ft., with CHIL-GLAS® #10 Reinforcing Mesh embedded into the first coat (yielding a dry film thickness of 0.09375 inch).

Large Insulated Expanses

•  For large insulated expanses, such as tank tops or horizontal surfaces, a two-coat application is recommended with CHIL- GLAS® #5 or #10 Glass Fiber Reinforcing Mesh embedded between coats; each coat is applied at a coverage rate of 6.35 gal./100 sq. ft. for a total coverage rate of 12.7 gal./100 sq. ft. (yielding a dry film thickness of 0.125 inch).

Suggested Specifications

Material Preparation

Do not thin. Stir well, but do not use sticks or boards which would splinter or otherwise contaminate the product. Apply only to clean, dry, oil-free surfaces. Keep container closed when not in use. CP-22 cannot be successfully applied by brush. CP-22 cannot be applied by spray. Not recommended for indoor use. Outdoor horizontal surfaces must always drain completely; a pitch of at least ½” per foot (4 cm/m) is required.

Uses

• CHIL-PRUF™ CP-22 has a broad application range as a vapor retarder 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™ is recommended for use in cold and dual temperature service.
• As a vapor retarder coating, it is used to protect insulation over fittings, piping, tanks, tank heads, process vessels and equipment.
• CHIL-PRUF™ also provides protection for insulation applied on underground pipelines.

Features & Benefits

Advantages

The highest quality asphalt used in Chil-Pruf™ CP-22 provides a higher softening point than other asphalts. This results in a longer service life, greater resistance to mechanical abuse, better weathering characteristics, greater flexibility in the cured coating and extreme resistance to weather cracking.
