Childers® Chil-Seal® CP-137 Anti-Fungal Protective Coating

• CP-137 AF coating is specially formulated with additional antimicrobials built into the coating to protect it from fungus or odor-producing bacteria on its surface.
• It is specially formulated with fungistatic agents to provide long-term resistance to mold or mildew growth on its surface.

• CP-137 AF coating is non-flammable in the wet state and fire resistive when dry.
• It contains no solvents to attack insulations or facings.
• The viscosity permits overhead and vertical applications that do not sag or run for additional ease of application.
• The combination of properties afforded by this material gives it great versatility both as an adhesive and a coating.
• The polymeric resins make this an adhesive of high bond strength and unusual permanence.
• The tough film is washable and is abrasion resistant.

• CP-137 AF coating is used for adhering fabrics such as glass cloth, canvas (up to 8 oz.) and brattice cloth to many insulated surfaces such as round and rectangular duct work and equipment.
• It is also used for adhering the laps of these fabrics as well as some woven glass cloths on pipe insulation.

CP-137 AF coating is easily applied by brush or spray. It is sometimes used for dipping canvas where more complete saturation and shrinkage is desired. The normal application is by brush; the bridging properties of this coating give a smooth finish even over relatively rough fabrics.

Pipe Insulation, Duct Insulation and Equipment:

• All insulation finished with canvas (or other fabric finishes) shall be bonded with and have their laps adhered with CHIL-SEAL® CP-137 AF coating.
• Apply only to clean, dry, oil-free surfaces. Apply a tack coat at 60 – 70 sq. ft. per gal. (1.5 – 1.7 m2/l). Immediately embed the selected lagging fabric into the wet coating.
• Smooth to avoid wrinkles and overlap seams by at least 2 inches (5 cm). Immediately apply a finish coat at 60 – 70 sq. ft. per gal. (1.5 – 1.7 m2/l).
• The dry film thickness of this application will vary with the fabric selected. For air conditioning ducts, increase the coverage rate to 40 – 50 sq. ft. per gal. (1.0 – 1.2 m2/l) for each coat.

Notes to Specifying Engineer:

• It is recommended that in using most types of pre-sized glass cloth facings, CHIL-STIX® FRN CP-82 Adhesive be used as the lap adhesive.
• The above suggested specification is for hot piping and equipment. It may be used for equipment operating as low as 55°F (13°C) in northern climates where a material with a perm rating of 1.3 is adequate.

Use of Material:

• Stir well, do not thin. CHIL-SEAL® CP-137 AF coating brushes easily.
• It should be stored indoors and above freezing temperatures, and should not be applied below 40°F (4°C) nor above 100°F (38°C) for best results.

The Condition of the Surface to Be Adhered or Coated:

• Certain surfaces which are dusty or porous such as calcium silicate or certain mineral fiber materials should first be primed with a light coat of CP-137 AF coating diluted 50% with water for proper bonding. A coating or adhesive will adhere no better than the integrity of the surface to which it is applied.

Application:

• This is easy to apply by brush or roller. The same procedure would be used when applying latex paints or similar brush-on coatings.
• Brushes or other tools should be kept in water and cleaned with hot, soapy water.
• CHIL-SEAL® CP-137 AF coating may be sprayed with many types of equipment, including airless spray.
• It may also be sprayed with conventional mastic spray equipment using an external atomizing spray gun.
• Many manufacturers of spray equipment can make detailed recommendations for any number of types of equipment.
• The spray equipment and techniques would be similar to those used for applying block fillers or heavy, latex paints.
• For best results, we suggested the following airless spray equipment.

Hints for Success:

• This is an excellent adhesive and also has good resistance to many chemicals and solvents.
• Spillage of this material should be cleaned immediately by washing with water.
• If it is allowed to dry, the best method for attempted cleanup is hot water, detergent and a wire brush.
• Always test foil and paper facing for acceptable adhesion before using.

Clean Up:

• Warm, soapy water (wet) or xylol (dry)
