Stabilized colored Rosin pentaerythritol ester

Jan 14, 2017

Water white resins containing double chain carboxyl and active, with conjugated double bonds and typical carboxyl group response. Outside of itself is easy to oxidation and isomerization, resin, Disproportionation, hydrogenation, addition, aggregate bond reaction. Also with esterification, aging, salt, decarboxylation and ammonia solution of carboxyl reaction. Secondary reprocessing based on Rosin resins double bonds and carboxyl groups reaction characteristics of resin-modified, generating a series of modified resin, improve the value.

Water white resins, is the result of stabilizing colored Rosin pentaerythritol ester.

Product characteristics: the product is lighter than the original color, with excellent heat resistance and weather resistance, in the EVA hot melt adhesive with good color stability. Dissolve in petroleum hydrocarbons, aromatic, ester, ketone, gasoline, benzene, ethyl acetate, acetone and solvents such as turpentine; not soluble in water and ethanol. This product has a light color, low odor, good resistance to oxidation and heat stability, adhesion, and other advantages. And good NR,CR,SBR,EVA,SIS and SBS polymer miscibility.
