Editing Adhesive (section)

=====Drying=====
There are two types of adhesives that harden by drying: ''solvent-based adhesives'' and ''polymer dispersion adhesives'', also known as ''emulsion adhesives''. Solvent-based adhesives are a mixture of ingredients (typically [[polymer]]s) dissolved in a [[solvent]]. [[Polyvinyl acetate|White glue]], contact adhesives and [[rubber cement]]s are members of the ''drying adhesive'' family. As the solvent evaporates, the adhesive hardens. Depending on the chemical composition of the adhesive, they will adhere to different materials to greater or lesser degrees.

Polymer dispersion adhesives are milky-white dispersions often based on [[polyvinyl acetate]] (PVAc). They are used extensively in the woodworking and packaging industries. They are also used with fabrics and fabric-based components, and in engineered products such as loudspeaker cones.
