3M™ Scotch-Weld™ Urethane Adhesive EC-3587 B/A

Designed for Impact
3M™ Scotch-Weld™ Urethane Adhesive EC-3587 B/A B-1/4 and 3M™ Scotch-Weld™ Urethane Adhesive EC-3587 B-1 are resilient to impact, providing a strong bond capable of withstanding shocks and collisions. Our urethane adhesive is also constructed to resist sagging approximately 30 seconds after mixing. Their non-sagging feature allows for more precise handling and accurate application. These adhesives cure at room temperature or with heat. This option gives you control over how quickly a bond establishes a certain level of shear strength. At room temperature, they have a handling strength in 7 days.

Upon application, 3M™ Scotch-Weld™ Urethane Adhesive EC-3587 B-1 offers a 60-minute work-life, presenting flexibility and providing ample time for adjustment and positioning to achieve optimum results. The 3M™ Scotch-Weld™ Urethane Adhesive EC-3587 B/A B-1/4 provides a 20-minute work-life for smaller applications and shorter time to handling strength.

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:

• 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
• 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
