Properties

Adhesion to a variety of substrates allows bonding of dissimilar materials if necessary. High cohesive strength is desirable. Flexibility improves peel strength by flexing with peel stress. High elastic modulus of substrate and adhesive resists stress at the bond line.

Composition

There are multiple chemistries for construction adhesives. Common ingredients include

clay Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolinite, ). Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impuriti ...
