The effect of maize starch on setting time of vinyl polysiloxane putty impression materials.

Maize starch is widely used as a glove lubricant, and the belief is commonly held that it is responsible for retarding the setting reaction of vinyl polysiloxane putty impression material (VPPIM). In contrast, our research demonstrated experimentally that maize starch glove lubricant (MSGL) did not inhibit but significantly (P less than 0.05) accelerated the setting reaction of VPPIM.
