Nuts & Bolts<br>Getting the Most Out of Chlorinated Polyolefin (CPO) Adhesion Promoters
There are several factors that can affect the performance of a CPO-based adhesion promoter. Application parameters play a significant role in designing a system that will provide optimum adhesion performance. Of particular importance is the temperature at which a coating applied to a PP or TPO part is cured or baked. In addition, substrate and CPO composition can influence overall adhesion performance.
This article will highlight the effects of coating bake temperature and adhesion promoter composition on the performance properties of coated TPO. It will also detail test results, such as gasoline resistance and peel strength, demonstrating how the two factors can affect the performance of a CPO under real-life applications. This information can be used as a basis from which to utilize a CPO adhesion promoter to meet specific needs.
