Handling/Application

Information (continued)

Coverage

Approximately 690 sq. ft./gal. sufficient to apply 345 sq. ft. of bonded surface on

most substrates such as decorative laminate and particle board. Optimum

performance is obtained using 2.5-3.5 grams/sq. ft. dry adhesive on each surface.

Note: Coverage will vary depending on the porosity of substrates and strength

of adhesive bond desired. For decorative laminate to particle board,

optimum performance is obtained at 2.5-3.5 grams of dry adhesive per

square foot applied to each surface. Depending on the user’s performance

requirements, less adhesive is suggested if fabrics, foams, etc. are to be

bonded. In all cases, user’s evaluation will be required to determine the

optimum coverage levels.

Activation Time

With proper mixing of adhesive and activator and depending on ambient conditions,

adhesive activates sufficiently to make bonds within 5-15 seconds after application.

Depending on ambient conditions and substrates, bonds should be made within (2)

hours. While bonds may be made immediately, the optimum initial strength will be

obtained by allowing the adhesive to dry the same amount of time as the previous

adhesive (solvent) type.

Assembly

For foam bonding and foam fabrication, pressure may be applied to the bond by

manual or mechanical methods. Bond adhesive coated surfaces with sufficient

pressure to assure good contact across adhesive bond line. For decorative laminates,

spacers such as dowels or strips of laminate may be used to help prevent premature

adhesive/adhesive contact and bonding prior to positioning. Slide out the spacers and

apply uniform pressure working toward the edges. A 3 inch roller used with

maximum body pressure should be used to help ensure adequate contact and bonding

especially on the edges. Bonded assemblies may be machined, trimmed, etc.

immediately after bonding. The use of a pinch roll is preferred for optimum

performance.

Cleanup

Work Surface: If adhesive has not activated, clean surfaces with water or with a

small amount of liquid detergent followed with a cleaner such as 3M™ Citrus Base

Cleaner or equivalent. Dried, activated adhesive may be cleaned with a combination

of cleaner and mechanical systems such as wire brushing.

Spray Equipment: Flush adhesive portion of spray equipment with cold water

containing a small amount of detergent* followed by a flush with clean water. The

activator portion of spray equipment should be flushed with clean water (no detergent).

*Cleaning Solution: One pint of detergent to five gallons of water.
