· Neopentylglycol (NPG), or 2, 2-dimethyl-1, 3-propanediol, is mainly used as a building block in polyester resins for coatings, unsaturated polyesters, lubricants and plasticizers.
· In powder coating formulations, Neopentylglycol offers the additional advantage of providing small differences between the glass transition temperature and melting point.
· Important areas of application include general metal, appliance, metal furniture, automotive and machinery coat.
