- Product Highlights
- CHIL-SEAL® CP-50A HV2 coating is non-flammable in the wet state and fire-resistive when dry.
- It contains no solvents to attack insulations or facings.
- The high 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 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.
Applications & Uses
- Markets
- Application Area
- Compatible Substrates & Surfaces
- Recommended Uses
- It 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.
- CHIL-SEAL® CP-50A HV2 coating is used as a coating over all of the above mentioned fabrics and also finds use as a coating over plastic foam materials such as polystyrene.
- CHIL-SEAL® CP-50A HV2 coating can be brushed on the joints of duct liner insulation to help prevent air erosion of the glass fiber.
- Application
- It is easily applied by trowel, brush or spray.
- The normal application is by trowel or brush; the bridging properties of this coating give a smooth finish even over relatively rough fabrics such as 8 oz. canvas and brattice cloth.
- Coverage Range
- Coverage will vary with nature of substrate, application technique and the applicator.
- 1.0 – 1.25 U.S. gal./100 sq. ft. (0.4 – 0.5 l/m2) per coat on canvas
- 1.25 – 2.5 U.S. gal./100 sq. ft. (0.5 – 1.0 l/m2) per coat on brattice cloth
- 1.0 U.S. gal./100 sq. ft. (0.4 l/m2) per coat on smooth dense surfaces
- Cleaning Information
Warm, soapy water (wet) or mineral spirits (dry)
- Suggested Specifications
Pipe insulation, duct insulation and equipment:
- All insulation finished with canvas (or other fabric finishes) shall have their laps adhered with CHIL-SEAL® CP-50A HV2 coating.
- A finish coat of CHIL-SEAL® CP-50A HV2 shall be applied to the entire outer surface of the lagging cloth at a coverage not less than 1 gallon per 100 sq. ft. (0.4 l/m2) for canvas or glass cloth and 1.25 gallons per 100 sq. ft. (0.51 l/m2) for brattice cloth.
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 in northern climates where a material with a perm rating of 1.0 is adequate.
- Preparation and Application Information
Use of Material:
- This brushes easily despite its somewhat heavy appearance. Stir well, do not thin.
- It should be stored indoors and above freezing temperatures and should not be applied below 40degreeF nor above 100degreeF 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 CHIL-SEAL® CP-50A HV2 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:
- CHIL-SEAL® CP-50A HV2 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 warm, soapy water.
- CHIL-SEAL® CP-50A HV2 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 sealers or heavy latex paints.
For best results, we suggest the following airless spray equipment.
Pump Graco NXT3400, 40:1 ratio, air regulator with Ram. Compressor Capable of 75 CFM and maintaining 100 PSIG. Fluid Hose High pressure capable of 4,000 PSI. 3/4
inch up to 100 feet. Use 8' (2.4 m) ½" I.D.
hose for coupling to the gun.Gun Graco Mastic or Textured Coating guns
with Reverse-A-Clean tips.Tip Sizes 627 to 635.
Hints for Success:
- CHIL-SEAL® CP-50A HV2 coating 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.
TopCoating:
-
If CP-50A HV2 is to be top coated with anything other than an alkyd enamel conforming to DOD-E-24607 as specified in MIL-A- 3316C, the user must confirm by his own tests that the products are compatible and that the final results are satisfactory.
