One often specifies, therefore, that the surface of the substrate be pretreated. Pretreatment methods can vary, from oxidation of the surface, e.g., plasma or flame, to diffusion and mechanical interlocking of an applied polymer with the surface. Mechanical interlocking with the nonpolar TPO surface can be achieved through the use of an adhesion promoter, namely a chlorinated poly(olefin) (CPO). The type of CPO utilized, in addition to the types of solvents and heat treatments utilized, can substantially influence the degree of adhesion/cohesion obtained within the CPO/TPO system. This article reviews the factors influencing the adhesion/cohesion of painted TPO substrates. Heat histories, TPO molding variations, CPO types, including solvent and resin variations, and topcoat (basecoat/clearcoat) chemistries are all found to influence the adhesion/cohesion of the painted TPO assembly (herein termed composite). Once adhesion of a topcoat system to the TPO substrate is achieved, however, the durability of that system to external forces is in question. External forces acting upon the painted composite, e.g., compressive stresses, tensile stresses, and single and/or multiple impact forces, can lead to devastating consequences. Chip or impact resistance and scratch or compressive/tensile (gouge) damage resistance can be affected by the choice of topcoat chemistries utilized. Topcoat frictional behavior, tensile strengths, and surface hardness were all determined to be influential factors in providing robust damage resistance to the painted composite.

A widely used technique for assuring paint adhesion to TPO is the use of adhesion promoter primers based on chlorinated polypropylenes (CPO). Much research has been focused on understanding the forces involved at the interfaces of substrate, adhesion promoter, and topcoats resulting in the adhesion or the loss of adhesion in various environmental conditions. This study correlates the adhesion performance of CPO and nonchlorinated adhesion promoters (NCPO) as measured by peel strength with properties observed through microscopy techniques. Adhesion performance of CPOs, NCPOs, and blends are quantified through the use of 90° and 180° peel strength studies. Surface characteristics of adhesion promoters applied over a TPO substrate and cured at various temperatures are examined through the use of atomic force microscopy (AFM).

The TPO investigated was a blend of high modulus polypropylene with an ethylene-butene copolymer (EBR9) containing 9 wt% butene. The CPO was a maleated chlorinated polypropylene containing 20 wt% Cl. The purpose of these experiments was to obtain detailed mechanistic information about the CPO-TPO interaction. To achieve acceptable contrast in these measurements, a fluorescent dye was covalently attached to a small portion of the CPO. Solvent wiping of the TPO substrates with isopropyl alcohol followed by xylenes prior to coating with CPO increased the mean roughness of the TPO surface by more than 100 nm; but it had a much larger effect on the roughness of the (several micrometers) CPO-TPO interface after coating. The EBR component of the TPO was shown to be exclusively responsible for the roughness increase. We also found evidence of a diffuse interface between the CPO and ERB components that was localized to sites in which the EBR was present at the TPO surface.
