A synthetic polymer with excellent aging characteristics that can be used as either a single component adhesive or a coating or saturant, depending upon composition. Acrylic adhesive systems are typically used for either indoor or outdoor applications with more critical permanent long-term bonding requirements.  Although acrylic adhesives are tacky by nature, often times a tackifier is added to enhance its quick-stick properties.  This is a benefit of acrylic adhesives – their polymers can be precisely adjusted during their industrial manufacturing process to improve the overall performance of the adhesive. Acrylic adhesives provide excellent environmental resistance and faster setting times than other resin systems. Acrylic films are plastic or thermoplastic resin films manufactured using polymethyl methacrylate (PMMA) or polymethyl-2-methylpropanoate. PMMA resins are the result of polymerization of acrylic acid derivatives or other acrylate compounds such as esters of acrylic acid, methacrylic acid, acrylonitrile and their copolymers. Acrylic films have good optical properties (clarity) and are UV stable. Plexiglas (Altofina Chemicals, Inc.) is a common acrylic sheet and film material. To make acrylic adhesives, plastic compounds are synthesized to obtain specific chemical structures that are tacky. Acrylics can be formulated to produce specific performance characteristics. This means acrylic adhesives have fair initial adhesion, gradual adhesion buildup, high shear strength, high temperature resistance, excellent solvent resistance, excellent UV resistance, excellent durability.
