Acrylic resin is a group of thermoplastic or thermoset related substances derived from acrylic acid, methacrylic acid or other related compounds. Polymethyl acrylate is an acrylic resin used in an emulsified form for lacquers, textiles, adhesives, and, when mixed with clay, for glossy paper. Another acrylic resin is polymethyl methacrylate, which is used to make hard plastic with various properties of light transmission. It is used for materials that require some properties of light transmission, since it is transparent as glass, some amount of titanium dioxide can be added for the translucent effect.

Formula
The chemical name for the resin produced from methyl methacrylate monomers (MMA) is polymethyl methacrylate (PMMA). MMA is a transparent and colorless liquid substance. The characteristic feature of PMMA is its high transparency. It is also very resistant to weather damage; it is not easy to turn yellow or crushed when exposed to sunlight and has been known to last more than thirty years. Polymethyl methacrylate is used for transparent and transparent items such as aquariums, signboards, car taillights, bathtub liners, sinks, mobile display screens, and optical backlight waveguides for liquid crystal display (LCD).

Advantages of paint in
Acrylic resin is a common ingredient in latex paints (English: "emulsion paint"). Interior and exterior latex paints with a larger proportion of acrylic resins, compared to vinyl, offer better stain protection, greater water resistance, better adhesion, greater resistance to cracks and blisters, and resistance to alkali cleansers. Acrylic resins are considered highly weather resistant. This makes it ideal for outdoor applications. In solid form acrylic resins can even survive for several decades. It is not yellow when exposed to sunlight, even after many years. Acrylic resin is a material that when added to latex (U.K. Emulsion) improves its gloss, mechanically scratch-resistant properties, making the paint more radiant than its solo performance.
Current and estimated market
Global demand for acrylic resin approximates approximately US $ 14.5 billion in 2011. With an annual growth rate of 4-5%, the acrylic resin market is estimated to reach $ 22 billion by 2020. Currently, acrylic resins are most commonly used in automotive parts, medical equipment, paints, coatings, adhesives, sealants, and construction.
Microbial degradation
Melanin-producing substances Cladosporium destroyed dry acrylic resin samples at the cathedral of Milan.
