Abstract: Plasticizer blends comprise a triblend of diethylene glycol dibenzoate, dipropylene glycol dibenzoate, and 1,2-propylene glycol dibenzoate, in specified ratios, useful in combination with a multitude of thermoplastic polymers, thermosetting polymers, and elastomeric polymers and numerous applications, including but not limited to plastisols, adhesives, sealants, caulks, architectural coatings, industrial coatings, OEM coatings, inks, overprint varnishes, polishes, and the like. The advantages rendered by the use of the triblend depend on the type of polymer and application in which it is utilized and include among other advantages higher solvating power and lower processing time, low VOC's, reduced plasticizer freeze point, improved gelation and fusion characteristics, higher tensile strength, superior stain and extraction resistance, and improved rheology over traditional diblends of diethylene glycol dibenzoate and dipropylene glycol dibenzoate.

Abstract: A novel, low volatility, non-phthalate plasticizer/coalescent blend for use in paints and other polymeric coatings comprises a triblend of diethylene glycol dibenzoate, dipropylene glycol dibenzoate, and 1,2-propylene glycol dibenzoate. The triblend when used in a paint or other coatings achieves a low VOC paint or coating having stable viscosity after three freeze/thaw cycles and equivalent or superior wet edge/open time ratings, gloss ratings, scrub resistance and block resistance when compared to traditional coalescents, including without limitation high VOC coalescents, low VOC non-dibenzoate coalescents and other dibenzoate blends. The triblend may be used as a substitute or alternative coalescent in latex and acrylic emulsion coatings, among others, to achieve a lower VOC content without sacrificing performance properties.

These combinations can replace at least a portion of the more volatile organic compounds without any decrease in coalescing ability of the polymers present in the composition.
