Structural Adhesives for Industrial Strength Attachment

Acrylic Adhesives

Reaching a minimum of 1,000-psi overlap shear strength, 3M™ Structural Adhesives are designed to bond the load-bearing parts of products. Powerful enough to replace mechanical fasteners and welds, these extremely high strength materials can bond metals, wood, rubber, ceramic, composites, engineering grade plastics, glass and much more. Applications are as vast as the industrial landscape itself, from appliance bushings and headlight assemblies to lawn sprinklers, office products, pump components, sporting equipment, electronics and furniture. 3M formulations include:

• Instant (Cyanoacrylate) adhesives: These high strength liquid formulations are commonly known as instant adhesives. On rigid plastic, glass, metal, rubber and other low porosity substrates, they harden in seconds by reacting with surface moisture.

• Polyurethane Reactive (PUR) Adhesives: These systems combine many production benefits typical of hot melt adhesives and bond performance usually associated with two-part structural adhesives. One-component, moisture curing formulation eliminates metering, mixing and curing equipment. And 100% solids give you a low-VOC adhesive system with no drying equipment and no attack on plastics.
