VOC Compliant Approaches to TPO Adhesion Promoters for Exterior Coatings Applications

Two possible approaches to reducing the VOC of adhesion promoters for TPO include: 1) Developing a means for lowering the VOC of solvent borne adhesion promoters while maintaining sprayability and performance and 2) Development and use of a waterbome adhesion promoter. Initial test results using both of these approaches have proven satisfactory when tested to an exterior automotive coating specification. While further testing is still necessary, these approaches have thus far proven themselves as viable methods for reducing the VOC of adhesion promoters for exterior automotive TPO applications.
