Pressure sensitive adhesives (PSA) and contact adhesives adhere to most surfaces with very slight pressure. They are available in solvent and latex or water-based forms. Pressure sensitive adhesives (PSA) and contact adhesives are often based on non-crosslinked rubber adhesives, acrylics or polyurethanes. Pressure sensitive adhesives form viscoelastic bonds that are aggressively and permanently tacky. They adhere with just finger or hand pressure and do not require activation by water, solvent or heat. Pressure sensitive adhesives are often based on non-crosslinked rubber adhesives in a latex emulsion or solvent-borne form.
Pressure sensitive adhesives (PSA) and contact adhesives are available in a wide variety of chemical compositions or systems. Some of the most common types of systems include acrylic and methacrylate adhesives, rubber-based pressure sensitive adhesives, styrene copolymers (SIS / SBS), and silicones. Acrylic adhesives are known for excellent environmental resistance and fast-setting time when compared with other resin systems. Acrylic pressure sensitive adhesives often use an acrylate system. Ethylene ethyl acrylate (EEA) or ethylene methyl acrylate (EMA) copolymers are used to form hot melt PSA adhesives. Natural rubber, synthetic rubber or elastomer sealants and adhesives can be based on a variety of systems such silicone, polyurethane, chloroprene, butyl, polybutadiene, isoprene or neoprene. Rubber and elastomers are characterized by their high degree of flexibility and elasticity (high reversible elongation). Styrene-isoprene-styrene (SIS) and styrene-butadiene-styrene (SBS) copolymers are commonly applied in pressure sensitive adhesive applications. Silicone is produced through the hydrolysis and polymerization of silanes and siloxanes.
