The present invention relates to a composition comprising triethylene glycol disorbate and triethylene glycol monosorbate, at a disorbate to monosorbate weight-to-weight ratio of from 19:1 to 99:1. The composition of the present invention is useful as a low VOC coalescent in coatings formulations.

High purity disorbate ester of triethylene glycol

The present invention is a composition comprising a solution or a dispersion of polymer particles, a sorbate ester or sorbamide curing agent, and a cure modulating additive for the curing agent. The curing agent is a sorbic acid ester or a sorbamide and the cure modulating agent is a reagent capable of accelerating or attenuating the rate of cure of the curing agent. The control of cure kinetics is important for speeding up cure rates where rates are too slow or by reducing cure rates where curing too rapidly results in undesirable color formation.

Sorbic acid ester containing coatings composition

The present invention is a composition comprising a stable aqueous dispersion of polymer particles and a sorbate ester, which is a liquid at 20&#xb0; C. and has a molecular weight in the range of 125 to 500 g/mol. The composition of the present invention provides a way to enhance film formation of coatings prepared using relatively high Tlatexes without the aid of high volatile organic content (VOC) coalescents.
