3 Neoprene Contact Adhesive 5 (Green and Light Yellow) Technical Data February, 2015 Product Description 3M Neoprene Contact Adhesive 5 is a sprayable contact adhesive which may be used to bond many high-pressure plastic laminates to wood, particle- board, metal and other surfaces. Features Sprayable. Fast drying. 60 minute bonding range. Excellent resistance to plastic flow (creep). Special Note When bonding wood veneers, success is dependent on many variables such as environmental conditions, bonding process, type of base material, type of veneer, adhesive type and top coat finishing systems to name a few. It is the users responsibility to thoroughly test any adhesive for its suitability in bonding wood veneers. It is also recommended to follow the veneer manufacturers recommendation and industry guidelines.

Information Surface Preparation 1. For best results all surfaces to be bonded should be dry and free from dirt, dust, oil, loose paint, wax, grease, etc. 2. Oil, grease and other contaminants can be removed by wiping with a solvent such as methyl ethyl ketone.* 3. If used for decorative laminate, laminate should have reached moisture equilibrium for the shop conditions. Working Temperature 1. The temperature of the adhesive and surfaces to be bonded should be at 65F (18C) or above. 2. Warm the can of adhesive by placing in a warm room, not in stove, oven or other possible ignition source. 3. If the room must be warmed, turn off the heater before opening container. 4. Leave heater off until all vapors are gone. Application 1. Stir thoroughly before using. 2. Apply adhesive generously in a uniform film on both surfaces with either a fiber or animal hair brush, or pour and spread with paint roller (solvent resistant texturing type). 3. Porous surfaces may require 2 coats of adhesive. 4. A glossy film when completely dry indicates adequate adhesive. 5. Dull spots after drying indicate not enough adhesive these spots must have another coat. Assembly 1. Allow to dry until adhesive is no longer tacky (5-10 minutes). 2. Position surfaces carefully before assembly. 3. No adjustment is possible after contact. 4. Spacers such as dowels or strips of laminate, may be used to prevent premature adhesive/adhesive contact and bonding. 5. Slide out the spacers and apply uniform pressure, working toward the edges. 6. A 3 in. roller used with maximum body pressure should be used to help ensure adequate contact and bonding, especially on the edges. 7. Bonded assemblies can be machined, trimmed or finished immediately after bonding. Drying Time 1. Drying time depends on temperature, humidity, air movement and porosity of materials bonded. Cleanup 1. Excess adhesive may be removed with a solvent such as methyl ethyl ketone.* *When using solvents, extinguish all ignition sources, including pilot lights, and follow manufacturers precautions and directions for use. - 2 -
