Foster® Chil-Grab™ Adhesive CP-122

• This adhesive penetrates quickly into the fibers and/or cells of the insulation; it creates a very strong bond to help prevent delamination.
• The chlorinated solvents used in manufacturing CHIL-GRABTM CP-122 make the adhesive non-flammable in the wet state for protection against fire hazards.
• The product sprays easily without misting, cobwebbing or clogging of spray equipment to help assure a trouble-free application.
• Since it is fast tacking, insulation can be almost immediately set into place, which helps provide high production rates.
• The use of low pressure, air assisted spray equipment provides a high coverage rate, which results in a high volume, economical application.

• This adhesive bonds vapor barrier jacketing and facing materials, such as foil faced kraft paper laminates (FSK) and All Service Jacketing (ASJ), to low density glass fiber, mineral fiber, polyurethane, and isocyanurate foam insulations.
• It is not to be used in conjunction with polystyrene insulation.
• The product provides adhesion between board stock insulation and the underlying surface of sheet metal or metal ductwork prior to final securement.

This adhesive is easily applied by low pressure, air assisted spray equipment. Where a brush or roller applied material is desired, use FRN CP-82 adhesive.

Adhesion of Vapor Barrier Jacketing to Insulation:

• All vapor barrier jacketing facing materials shall be laminated to glass fiber (or mineral fiber, polyurethane and/or isocyanurate) insulation with CHIL-GRABTM CP-122 adhesive.
• The adhesive shall be applied at a coverage rate between 450 to 600 sq. ft./U.S. gal. (11.0 to 14.7 m² /liter).

Adhesion of Insulation to Metal Ductwork:

• All glass fiber (or mineral fiber, polyurethane and/or isocyanurate) insulation shall be temporarily adhered to the underlying metal ductwork with CHIL- GRABTM CP-122 adhesive prior to final securement with specified mechanical fastening devices.
• The adhesive shall be applied at a coverage rate between 450 to 600 sq.ft./U.S. gal. (11.0 to 14.7 m² /liter).

Safety Precautions:

• This adhesive is manufactured with non-flammable chlorinated solvents, and therefore poses no fire hazard in the wet state.
• Keep the container tightly closed when not in use. Use only in well ventilated areas.
• This product may be an eye irritant; protect eyes at all time. Avoid prolonged breathing of vapors and prolonged or repeated contact with skin.

Use of Materials:

• Stir well, do not thin. Optimum storage conditions are between 55^oF to 80^oF. Lower storage temperatures may cause a temporary increase in viscosity with a resulting difficulty in spraying.
• Higher storage temperatures will shorten the shelf life of the product. Although it will not freeze, it is recommended that it not be applied at temperatures less than 40^oF since condensation on the metal substrate (blushing) may occur, which may retard drying time and/or adversely affect the bond strength.
• Do not apply the adhesive at temperatures above 100oF (38oC) since blistering may occur. All metal surfaces should be clean, dry and free of oil or grease to assure the best possible bond.
• No primer is necessary over aluminum or steel. The solvents in CHIL-GRABTM CP-122 adhesive will attack polystirene insulation.
• The user should determine through prior testing that this adhesive may be used with the specific materials and under the application conditions which exist.

Application:

• This is designed for application by low pressure air assisted spray equipment. (There are three general types of low pressure spray equipment available, and they are listed below. The types and model numbers of units suggested do not imply endorsement of any one unit, nor assurance of their applicability under the user’s requirements. Spray equipment must not contain aluminum parts.)

*This kit comes with a pressure pot having only one pressure gage. It is recommended that a pressure tank with two gages be substituted.

• For adhering low density insulation, the adhesive should be sprayed directly onto the metal (or other) substrate.
• A speckled pattern gives the most effective bond; 100% coverage is neither necessary nor desired.
• The insulation should be bonded to the metal within 10 minutes of spray application while the adhesive is still wet.
• If it is too dry, an insufficient bond will result. Too much adhesive can be as bad as too little. If the speckles are too small, the atomizing pressure is too high and should be cut back (the adhesive will also dry too fast if this is the case).
• spraying, hold the gun perpendicular to and about 12” (30 cm) from the surface to be sprayed.
• Trigger the spray gun at the end of each pass; this will help eliminate clogging or adhesive build-up at the gun tip.

Hints for Success:

• All material hoses should be resistant to chlorinated solvents.
• Packings and glands in contact with the adhesive should be made of Teflon®. When spraying, trigger the spray gun at the end of each pass.
• This helps eliminate clogging or adhesive build-up at tip. Hold gun perpendicular to and about 12” (30 cm) away from the surface to be sprayed. A speckled pattern gives the most effective bond.
• This is not a paint do not try to completely cover the surface.
• Place the insulation into the adhesive while it is still wet--do not allow it to dry too much or an insufficient bond will result.
• Too much adhesive can be as bad as too little. If the speckles are too small it means that the atomizing pressure is too high, and should be cut back (the adhesive will also dry too quickly if this is the case).
• Spray equipment must not contain aluminum parts.
