Hydroxyl neopentyl glycol pivalate is called 3-hydroxyl-2. 2-neopentanoic acid-3-hydroxyl-2. 2-neopentyl ester, 1115Ester by UCC Company of USA or HPHP by Easman Company in short.
The product is white solid, its molecular formula C10H20O4, its molecular weight 204. 3, its melting point 46-51℃, its boiling point 292. 5℃ and its specific gravity（D420)1. 04. It is of a little water absorption and easy to dissolve in alcohol, ether, etc. Organic solvents and its solubility is 27. 4%(25℃)in water.
The product is a new generation of high-level multi-element alcohols after pentaerythritol, trihydroxymethyl propane and neopentyl glycol. Owing to special molecular structure of the product, ester composed with the product is of high boiling point, can keep strict recipe ratio and raise stability. The paint film made of the product is of higher tensile property, elongation, heat resistance, creasing resistance and abrasion resistance, can raise luster of and persistance of the luster of the paint film and is of good contamination resistance. The product is an indispensable raw material for synthetic resins, unsaturated polyesters, high elastic coatings, coatings for color reeled veneer, paint for high-level enamel-covered wire, high-level lube, special cohesive material, iron-printing ink, lighting lacquer, etc. To improve product property, raise product quality and renew product grade.
