Abstract
Disclosed is the use of glycol ether aryl ester plasticizers as viscosity reducing agents in plastisols comprising di(2-ethylhexyl) terephthalate, 1,2-cyclohexane dicarboxylic acid diisononyl ester, or diisononyl phthalate as the primary plasticizer. The glycol ether aryl ester plasticizers improve viscosity and viscosity stability while maintaining or improving plastisol properties such as Shore A Hardness and fusion time.
