Abstract
An adhesion promoter for non-conductive surfaces is disclosed that combines a polyolefin with co-resins in a colloidal suspension in water. The colloidal suspension in water is prepared from mixing a solid-powder composition that includes the polyolefin and the co-resins with water. The colloidal suspension in water is applied to a low surface energy, non-conductive substrate, such as thermoplastic olefins, in order to make the substrates conductive for electrostatic painting.
Claims16
A method of preparing a low surface energy, non-conductive substrate for electrostatic painting, comprising:
- a. preparing a water-based slurry comprising a conductive agent;
- b. applying the water-based slurry to a low surface energy, non-conductive substrate to prepare a wetted, low surface energy, non-conductive substrate;
- c. preparing a dry solid-powder composition comprising co-resins and a polyolefin;
- and
- d. applying the dry solid-powder composition to the wetted, low surface energy, non-conductive substrate.
