Chlorinated polyolefins (CPO); Adhesion promoter

Abstract

"The purpose of this research was to examine the effect of chlorinated polyolefins (CPO), applied during injection moulding, on the adhesion of paint to polypropylene (PP) or thermoplastic polyolefin (TPO).

Previous literature has shown that CPO increased the adhesion of paint to plastic when applied in a traditional way. In order to save time and energy of a post mould coating process, CPO was applied at the time of moulding. Cloth peel test on Instron was used to measure the peel strength. Scanning electron microscope (SEM), with energy dispersive spectroscopy (EDS), along with X-ray photoelectron spectroscopy (XPS) was used to determine the mode of adhesion failure. Peaks of C 1 s ( carbon 1 s) emission spectrum for the peeled samples were compared with those of controls to decide the mode of adhesion failure.

Results showed that traditionally applied CPOs (both waterborne and solventbome) worked better than injection moulded samples for increasing the adhesive strength of polyurethane paint to PP or TPO. Solventbome CPOs worked better than waterborne CPOs. For injection moulded samples increase in adhesion was observed but it diminished with successive samples. Both adhesive and cohesive failure was observed for injection moulded samples"--Abstract, page iii.
