讨论了一种最近获得专利的用于热塑性烯烃（TPO）基材的零VOC粘附促进剂（底漆）。这种汽车认证的水基零VOC产品有可能将典型TPO涂装工艺的VOC排放总量减少一半。它还可用于为TPO表面涂底漆，以便随后使用常规粘合剂进行粘合。

A RECENTLY PATENTED ZERO VOC ADHESION PROMOTOR (PRIMER) FOR USE ON THERMOPLASTIC OLEFIN (TPO) SUBSTRATES IS DISCUSSED. THIS AUTOMOTIVE APPROVED WATER BASED, ZERO VOC PRODUCT HAS THE POTENTIAL FOR REDUCING THE OVERALL VOC EMISSION OF A TYPICAL TPO PAINTING PROCESS IN HALF. IT MAY ALSO BE USED TO PRIME TPO SURFACES FOR SUBSEQUENT BONDING USING CONVENTIONAL ADHESIVES.
