3M™ Scotch-Weld™ Urethane Adhesive 608 is a rapid-setting, two-component polyurethane with a 1:1 mix ratio and 24 hour cure rate. Non-sag after dispensing, it can be used as a horizontal and vertical grade adhesive for bonding sheet metal structures in lieu of welding.
Creates an Extremely Strong, Flexible Bond
This non-sag, two-component adhesive is flexible, conformable and capable of bonding dissimilar substrates including concrete, ceramic, wood, plastic, rubber and metal. With a 1:1 mix ratio, 3M™ Scotch-Weld™ Urethane Adhesive 608 features a 10-minute work life, 24 hour cure rate, and reaches handling strength in 90 minutes. Duo-Pak cartridges require the use of our 3M™ Scotch-Weld™ EPX™ Plus II applicator and mix nozzles (not included).
Bonding of dissimilar substrates, such as concrete, ceramic, wood, plastic, rubber and metal
More about Structural Adhesives
Polyurethanes are a class of polymers generally noted for their flexibility when cured. Two-part polyurethane adhesives comprise two components designed to be mixed, like an epoxy adhesive. The isocyanate, generally the accelerator or hardener side, reacts with the polyol or resin side when mixed, curing more quickly than one-part, moisture cure polyurethane systems, and with no depth of cure issues.
Urethane adhesives will work on most common materials such as wood, metals, rubbers, cured epoxy, leather, tile and glass, many plastics, concrete and more. The versatility of urethane adhesives comes from its chemical recipe; different chemical combinations result in different properties that produce different levels of stiffness, density, flexibility or hardness. Upon curing, urethanes may be quite flexible or relatively rigid, to meet a wide range of requirements. Urethane adhesives are generally resistant to environmental factors such as temperature, moisture and chemical exposure.
