Acrylic Resins

Acrylic resins
Acrylic Resins are the product of polymerization of Acrylic acid, Methacrylic acid and their derivatives. They are classified in two groups of solvent-based and water-based. Coatings that prepared from acrylic resins have better stability and durability than alkyd coatings and other coatings based on drying oils and they have lower VOC content. Among their most important characteristics, fast drying, excellent clearness and brightness, high UV resistance, high moisture resistance, long life and high thermal resistance are considerable.
Solvent-based Acrylic resins
This type of resin is categorized under two groups of Thermoplastics and Thermosets.

Solvent-based thermoset Acrylic
They are polymers with short length chains (low molecular weight) and active functional groups. Under certain temperature conditions, they react with themselves and or other resins having active functional groups. They are mostly applied in manufacture of stove paints, Polyurethane foams, etc.
Solvent-based thermoplastic Acrylic
They are air-drying and are mostly applied in manufacture of traffic paints, decorative paints and coatings on wood and stone, etc.


Water-based Acrylic resins
Using this type of acrylic is a proper way to reduce usage of organic solvents and therefore reaching a lower level of toxic volatiles. They are applied in paints, concrete, adhesives and textile industries.
