Product Description
Neopentyl glycol is used in the synthesis of polyesters, paints, lubricants, and plasticizers. When used in the manufacture of polyesters, it enhances the stability of the product towards heat, light, and water. By esterification reaction with fatty or carboxylic acids, synthetic lubricating esters with reduced potential for oxidation or hydrolysis, compared to natural esters, can be produced. NPG is used primarily in base resins for coatings. 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 coatings. Important uses are also found in hydraulic fluids, synthetic lubricant oils, greases, metalworking fluids and aircraft engine lubricants. Other outlets include textiles, pharmaceuticals, pesticides, plasticizers and petroleum.
