Multibond Contact Cement is a solvent free water based neoprene contact adhesive. It offers fast dry times and excellent tack. It can be used in post forming operations and can be applied by spray equipment, brush, or roller. It has high heat resistance and is non-flammable. It can bond decorative laminate, leather, rubber, particleboard and other wood-based composites.
Chemical family description: Polychloroprene latex Appearance: Off-white colored Typical viscosity (cps): 1800-2200 Weight solids (%): 53.0 - 57.0 pH: ~11.0 Specific gravity: 1.09 Weight pounds per gallon: 9.10 Suggested minimum use temperature: 60°F/ 15°C
Stock preparation: The preparation of the stock to be glued is extremely important. Gluing stock should be uniform in thickness. Variation in thickness should not exceed ± 0.005 inches/0.12 mm. Sanding to thickness should be performed using higher than 50 grit abrasives. The surface must be free from dirt, oil or other contaminants. Do not use on vinyl due to plasticizer migration.
Spread: Generally, when brushing or rolling apply a minimum of 3.0 dry grams/square foot. If spraying 2.5-3.5 dry grams should be applied. For porous substrates, it is best to apply two coats allowing the first coat to dry. A Web-based spread calculator can be found at www.franklinadhesivesandpolymers.com.
Pressure: Pressure is dependent upon the species or material to be glued and joint preparation. Direct contact of the gluing surfaces is required to obtain maximum strength. Pressure must be uniform; a pinch roller is allows for the best pressure. A Web-based pressure calculator can be found at www.franklinadhesivesandpolymers.com.
Dry time: The adhesive must be fully dry prior to bonding pressure. Waterborne contact adhesives change color when dry. To check for dryness, use the back of your fingers and press into the adhesive film and lift up. If the adhesive transfers or there is any legginess, more dry time is needed. Bonds must be made with in two hours after the adhesive has dried are as strong as those made immediately after dry. Dry times can be accelerated with the use of air movement.
Machining/ post process conditioning: After the minimum clamping time period, the panel will develop enough strength to be immediately machined.
Minimum use temperature: Curing temperatures should be higher than the minimum use temperature of the adhesive. This includes the temperature of the stock to be glued as well as the air and adhesive temperatures. If the temperatures are below the minimum use temperatures you will see a white, chalky appearance of the glueline. These bonds are usually weak. Suggested application temperature is 60˚ F to 90˚F (15˚C to 32˚C).
Clean-up: For easy removal of adhesive from equipment, clean up while it is still wet with warm water (this includes the glue roller and pans). For dried glue, use mineral spirits. Using glue release agents on equipment will also allow for easier clean up.
Shelf life: Best if used within twelve months of date of manufacture. Product is not freeze thaw stable. Frozen product will have a separated and or lumpy appearance. Store material above 65°F/18°C. Do not store in direct sunlight. Do not use materials made with copper or copper alloys to store or apply adhesive.
