Celanese Propylene Glycol cuts Glycol costs in Emulsion Paints

Celanese Propylene Glycol cuts Glycol costs in Emulsion Paints • Saves up to I71/a< per gallon of glycol • Improves scrub-resistance of PVAc paints « No change in freeze-thaw or shelf stability • No detectable difference in wet-edge time

Emulsion paint manufacturers will be interested in the results of recent technical studies in which propylene glycol was substituted for more expensive ethylene glycol in selected formulations of interior flat paints. At the Celanese Applications Laboratory a comparison was made of effect of both ethylene and propylene glycol on general paint properties of PVAc, styrene-butadiene and acrylic emulsions. In each case propylene offered the same properties as ethylene glycol, but at a substantially lower cost. Formulating with propylene ($1.0825/gal.) instead of ethylene ($1.2569/gal.) can save emulsion paint manufacturers up to 17V20 per gallon of glycol used. In addition to cost savings, laboratory tests (substituting the two glycols on an equal weight basis) showed no detectable difference in wet-edge time, shelf or freeze-thaw stability of the paints. Both glycols provided paints equal in color uniformity, sheen uniformity, colorability, reflectance, dry opacity, 85° sheen, and stain removal. And in the case of PVAc paints, propylene glycol provided even greater scrub resistance during the tests.
