Acrylic adhesives are made from monomeric esters and from solutions of polyacrylates in the monomers themselves, in inert organic solvents or in mixtures of the monomers and solvents. Modifiers added to acrylic adhesives to control viscosities and elasticity of the hardened compositions and to improve the strength of bonding and the resistance to high temperature include vinyl acetate, styrene butadiene and other monomers, phenol formaldehyde, urea-formaldehyde, and epoxy resins, cellulose esters, rubbers, and fillers and plastisizers. A photoinitiator is also added to acrylic adhesives which decomposes to yield free radicals. These free radicals then initiate polymerization through acylate group and form thermoset polymer.
Acrylic adhesives are supplied as one-part with viscosities ranging from 50cP to thixotropic gels. Upon exposure to ultraviolet (UV) or visible light of proper intensity and spectrum output, these adhesives cure rapidly to form thermoset polymers with excellent adhesion to wide variety of subtrates. Cure times of 2-60 seconds are typical. Bonding surfaces range from glass, plastics, paper, silicates, organic including glass parts for optical instruments. Pressure sensitive Adhesives (PSA) commonly use acrylic based adhesives for numerous applications including labels.
