What to Know About Urethane Adhesives
Polyurethanes are a class of polymers generally noted for their flexibility when cured. Two-part polyurethane adhesives comprise two independent formulations designed to be mixed, much like an epoxy adhesive. 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 their chemical formulation; different chemical combinations result in different properties that produce different levels of stiffness, density, flexibility or hardness. Therefore, urethane adhesives can cure to relatively rigid or more flexible bond lines, to meet a wide range of requirements. In either finished state, urethane adhesives will maintain bond strength integrity through good resistance to 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 3535 provides several advantages, such as:
Eliminates the need to damage surfaces (i.e. drilling holes)
Joins dissimilar materials and works well with many surfaces
Provides aesthetically pleasing results as refinishing steps are not required
Offers the highest load bearing capability
Good environmental and chemical resistance
Delivers excellent temperature and solvent resistance
Does not need access to air or moisture to dry and therefore has an unlimited depth of cure
