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.
