Childers® Chil-Stix® FRN CP-82 Adhesive

• Chil-Stix® FRN CP-82 Adhesive is best applied by brush.
• Chil-Stix® FRN CP-82 Adhesive is non-flammable in the wet state and fire resistive when dry.
• The dry bond properties of Chil-Stix® FRN CP-82 make it advantageous for use as a vapor barrier lap adhesive.
• This adhesive is easy to brush.
• It is a fast-drying, neoprene adhesive which actually becomes stronger with age.
• A tight, unbreakable bond is immediately formed upon contact of the two coated surfaces.
• Non-flammable, chlorinated solvents eliminate explosion and fire hazards during application.

Adhesion of Blanket Insulations to Ducts

• All fibrous glass (or other) insulations shall be applied to duct using CHIL-STIX® FRN CP-82 Adhesive.
• Entire sheet metal duct surface shall receive a coat of CHIL-STIX FRN CP-82 Adhesive applied at a maximum coverage of 250 sq. ft./gal. (6.1 m2/l).

Note to Specifying Engineer 

• Since an adhesive has no better strength than the material it is adhering, and since most insulations such as fibrous glass tend to delaminate, it is desirable in most cases to use welded pins or adhered clips and retaining washers as useful adjuncts to securement.
• Such welded pins or clips are usually fastened on 18 – 24 inch (45 – 60 cm) centers and are necessary in duct lining work or across the bottoms of ducts that are being wrapped.

Laps of Vapor Barrier Jackets on Pipe and Duct Insulation

• All laps of factory-applied jackets and tapes for butt joints shall be adhered with CHIL-STIX® FRN CP-82 Adhesive. Minimum overlaps shall be 2 in. (5.08 cm). Laps should be smooth and continuous.

Laps of Pre-sized Glass Cloth Pipe Covering Jackets

• All laps of pre-sized glass cloth pipe covering jackets shall be adhered with CHIL-STIX® FRN CP-82 Adhesive, smoothing out all wrinkles to ensure a smooth, attractive finish.

Use of Material

• CHIL-STIX® FRN CP-82 is a pigmented adhesive, which should require very little mixing.
• Sometimes upon standing there will be separation, requiring some mixing before using.
• Do Not Thin.
• Although it will not freeze at low temperatures, it is suggested that CHIL-STIX® FRN CP-82 Adhesive not be applied at temperatures lower than 40°F (4°C) due to the possibility of condensation or frosting on metallic surfaces, which retards drying and inhibits bonding.
• Applications made at temperatures exceeding 100°F (38°C) may result in blistering. Use only in well ventilated areas.
• Avoid prolonged breathing of vapors and prolonged or repeated contact with skin.

The Condition of the Surfaces to Be Coated

• CHIL-STIX® FRN CP-82 Adhesive may be applied over almost any type of substrate.
• It is advisable that metal surfaces be as oil-free as possible.
• No primer is required over galvanized steel to gain maximum adhesion.
• Do not apply over wet or damp surfaces, as the adhesion will be affected.

Application

• CHIL-STIX® FRN CP-82 Adhesive is a brush adhesive.
• When used as a contact cement, apply CP-82 to both surfaces.
• Allow it to dry before bonding.
• For adhering light density insulation such as fibrous glass blanket to sheet metal duct, the CHIL-STIX® FRN CP-82 Adhesive should be brush applied at a maximum coverage rate of 250 sq. ft./gal. (6.1 m2/l).
• It is not necessary to prime galvanized steel or aluminum.
• The insulation should be firmly embedded into the adhesive immediately after the application of the adhesive, making sure there is complete contact.
• It is advised that the user determine the best bonding period based upon the particular working conditions such as temperature, humidity and air movement.
• It is suggested that the adhesive be applied in 100% coverage.
• It is advisable to use mechanical fastening devices such as welded pins, particularly on the bottom of wide ducts or other overhead applications.
• The solvents in this adhesive will attack polystyrene foam and might attack certain other plastic foams, films or laminates.
• The user should determine by prior test that this adhesive may be used with a specific material and under the application conditions which exist.
• For adhering the laps of pre-sized glass cloth, the adhesive may be applied to the under side of the lap, and then when tacky, the lap should be firmly adhered working from the center of the section outward to ensure a smooth, surface finish.
• For adhering the laps of vapor barrier jackets, as on pipe insulation, it is suggested that the adhesive be applied at a heavier rate than for applying blanket insulation.
• It is preferable to coat both surfaces of the jacket, or as an alternate, coat the underside (foil side), strike the lap and wait until the adhesive is dry so that none is transferred to the finger when touched.
• The time allowed for sealing can be as long as several days.
• Jackets may have adhesive applied to the lap in advance and sealed after the adhesive is dry.
• In all cases of lap adhesion, it is suggested that the laps be sealed together by working from the center outward, to ensure a smooth, surface finish.

• Chil-Stix® FRN CP-82 Adhesive adhesive is ideal for adhering many types of insulations such as fibrous glass, laminated scrims, foils, many plastic films and various foams, both flexible and rigid.
• The solvents in this adhesive will attack polystyrene foams and may attack certain other plastic foams, plastic films and plastic laminates.
• Chil-Stix® FRN CP-82 Adhesive effectively adheres the laps of most types of vapor barrier jackets.
• Because of its superior contact properties, it finds many uses both inside and outside of the insulation industry.
