... contaminants by water break tests, where a clean (bondable) surface is indicated by the formation of a continuous film of clean water on it. Pressure-sensitive adhesives (PSAs), such as those used on tapes and labels, may appear not to fit any of the schemes above. However, they might actually be...

A low-viscosity adhesive will have a thin optimum bond line thickness, and a higher-viscosity adhesive will require a thicker bond line to achieve optimum performance characteristics such as bond strength and long-term bond reliability. Adhesive development of resin systems has intensified...

... forms, from low-viscosity liquids to solid pastes or films. During the curing process, epoxy adhesives polymerize and crosslink to form covalent bonds between the epoxy resin and hardener through an epoxide ring-opening reaction. Amines, amides, mercaptans, and anhydrides are common hardeners...

... coatings sliding against steel, superior adhesive wear resistance can be attributed to the in situ formation of a transferred, low-shear, thin graphitic film, which blocks the creation of adhesive bonds between the contact surfaces ( Ref 165 , 166 ). However, coating selection is greatly influenced by the...
