What is Urethane Adhesive?
Urethanes are a class of polymers generally noted for their flexibility when cured. Two part urethane adhesives comprise two independent formulations designed to be mixed, much like an epoxy adhesive. The isocyanate stream, generally the accelerator or hardener side, reacts with the polyol or resin side. These two components will react 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. They can cure to a solid and be relatively rigid, or cure to a semi-hardened state and remain flexible to meet a wide range of requirements. In either finished state, urethane adhesives will maintain bond strength integrity through variable environmental factors such as temperature, moisture and chemical exposure.
The Benefits of Using a Structural Adhesive
Utilizing a structural adhesive like 3M™ Scotch-Weld™ Urethane Adhesive EC-3587 B/A comes with several advantages, such as:
Our Best for Your Best
- Eliminates the need to damage surfaces (i.e. drilling holes)
