Handling/Application

Information

Directions For Use:

1. Surface Preparation: Surfaces must be clean, dry and dust free. Wiping with a

solvent such as 3M™ Solvent No. 3* will aid in removing oil and dirt.

Temperature of adhesive and surfaces during fabrication should be at least 65°F

(18°C). If used for decorative plastic laminates, the laminate should have reached

moisture equilibrium for the shop conditions.

2. Application: Apply a uniform, generous coat of adhesive to both surfaces with a

nylon brush, roller (texturing type), or spray. One coat is usually sufficient on most

surfaces. Dull spots when dry indicate insufficient adhesive. Very porous material

may require more than one coat. (Allow adhesive to dry completely between coats.)

A uniform, glossy film indicates sufficient adhesive.

3. Coverage: Coverage is dependent upon porosity of the substrate and the method by

wood, particle board and high pressure laminates with the adhesive applied by

spray or roller. More adhesive (lower coverage) is recommended if very soft wood,

fabrics, foams, etc. are to be bonded, or if the adhesive is applied by brushing.

4. Drying Time: The adhesive dries sufficiently in 30 minutes under normal

temperatures and humidities to make bonds. High humidity will slow the drying;

high temperature will speed the drying. After the adhesive is dry the bond must be

completed within four hours.

5. Assembly: Spacers, such as dowels or strips of laminate, may be used to help

prevent premature adhesive to adhesive contact and bonding prior to positioning.

Slide out the spacers and apply uniform pressure, working toward the edges.

A 3 in. wide (maximum) roller with maximum body pressure should be used to

help ensure adequate contact and bonding, especially on edges. Bonded assemblies

may be machined, trimmed, etc. immediately after bonding. The use of a pinch or

nip roll is preferred for optimum performance.

6. Cleanup: If adhesive has not dried, clean equipment with water containing a small

amount of detergent.** Adhesive cannot be cleaned off rollers or brushes after it

has dried.

*When using solvents, extinguish all ignition sources, including pilot lights, and

follow the manufacturer’s precautions and directions for use.

**Cleaning solution: One pint of cleaner to five gallons of water. Flush with clean

water.
