Bond Performance Bond Strength = Adhesion + Cohesion Adhesion = attraction between adhesive and substrates Adhesion affected by substrate: • Surface energy, surface prep, roughness, contamination, additives Adhesion affected by adhesive: • Chemistry, cure speed, viscosity Cohesion = internal strength of the adhesive Cohesion affected by adhesive: • Chemistry, crosslink density, modulus, tensile strength, cure profile

Mechanisms of Adhesion Chemical • Via molecular contact at the surface of the substrate • Strongest mechanism of adhesion • Primary interactions: metallic < covalent ≤ ionic • Secondary interactions: van der Waals < hydrogen bonding < Lewis acid/base Mechanical Interlocking • Adhesive flows into the pores of the substrate’s surface – creating a “lock and key” • Physical impediment to crack propagation at the interface • An increase in the surface area – more contact = more interactions = higher strength Diffusion • Polymer in adhesive is capable of entangling with polymer in substrate • Interface is created with entangled polymer chains (i.e., interpenetrating networks) • Common with difficult-to-bond low surface energy materials (e.g., polypropylene) Electrostatic • Charged surface of the adhesive is drawn towards the oppositely charged substrate • Most common in tape applications

They can positively impact production efficiency, appearance, and performance. • There are several markets and application types where structural adhesives can be used. • 3M has 6 structural adhesive chemistries: epoxies, acrylics, urethanes, PURs, aerobics and instants. • There are 9 global Go To Products for structural adhesives. • Work life, handling time and full cure time are key terms to understand for structural adhesives • 3M’s product nomenclature has meaning. For example, in DP420, “DP4xx” represents a toughened epoxy and “20” is 20-minute work life. • A framework to use when discussing bonding with customers is ASPEC.
