- CP-137 HF-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 HF-AF Protective Coating is used for adhering fabrics such as glass cloth, canvas 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 HF-AF is used as a protective coating over all of the above-mentioned fabrics and also finds use as a coating over plastic foam materials such as polystyrene.
- CP-137 HF-AF coating can be brushed on the joints and edges of duct liner insulation to help prevent air erosion of the glass fiber.
- CP-137 HF-AF is normally applied by brush; the bridging properties of this coating give a smooth finish even over relatively rough fabrics such as 8 oz. canvas and brattice cloth.
- May also be applied by airless spray.
- Meets NFPA Standard 90A & 90B 25/50 requirements.
- Meets the performance requirements of MIL-DTL-3316D, Class 1, Grade A.
- CP-137 HF-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.
- The tough film is washable and is abrasion resistant.

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 CP-137 HF-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
- The above suggested specification is for hot piping and equipment.
- It may be used for equipment operating below ambient temperatures where it is used as protection over foil faced insulations where the foil facing is taped and sealed and has a perm rating of <0.02 perms.
- If CP-137 HF-AF is to be top coated with anything other than an alkyd enamel conforming to DOD-E-24607 as specified in MIL-DTL-3316D, the user must confirm by his/her own tests that the products are compatible and that the final results are satisfactory.
- Preparation and Application Information
Use of Material
- CP-137 HF-AF coating brushes easily despite its somewhat heavy appearance.
- 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.
- Stir well, do not thin.
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 HF-AF adhesive 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.
- Not suggested for outdoor use.
Application
- CP-137 HF-AF coating is extremely easy to apply by brush and the same procedure would be used as applying latex paints or similar brush-on coatings.
- Brushes or other tools should be kept in water and cleaned with hot, soapy water.
- CP-137 HF-AF coating may be sprayed with many types of equipment, including airless spray. Average viscosity range: 70,000 – 90,000 cps. For best results, we suggested the following airless spray

- CP-137 HF-AF coating is an excellent adhesive and also has good resistance to many chemicals and solvents. Spillage of this material should be cleaned immediately.
