Acrylic polymer (resins)

An alkyd is a polyester modified by the addition of fatty acids and other components. Decorative gloss paints typically contain alkyd polymers (resins). Alkyds are used in paints and are the dominant resin or binder in most commercial oil based coatings. A typical resin is that produced from polyol such as propan-1,2,3 triol (glycerol) with a dibasic acid such as benzene-1,2- dicarboxylic (phthalic) anhydride and a drying oil such as linseed or soybean oil.

Paints produced using alkyd resins provide a lustrous, high gloss, and durable finish. Alkyd paints or oil based paints are resistant to wear and tear, humidity and moisture and also heat resistant paints.


Acrylic resins are group of related thermoplastic or thermosetting plastic substances derived from acrylic acid, methacrylic acid or other related compounds. The commonly used acrylic is polymethi methacrylate (PMMA). The material can be utilized as a casting resin in inks and coatings and has many other uses.

Polymethyl methacrylate (C5O2H8)

Acrylic is one of the common ingredients in latex or emulsion paint. Interior and exterior latex paints with greater proportions of acrylic resin offer:

  • Better stain protection.
  • Water resistance.
  • Better adhesion.
  • Resist cracking and blistering better.
  • Resistant to alkali cleaners.
