Conductive Emulsion for Preparing Surface for Powder Coating

Abstract
The present invention provides an environmentally friendly conductive sol-gel emulsion for surface treatment of low-conductivity objects. The emulsion renders the object amenable to powder coating or other treatments that require the surface of an object to be conductive. The sol-gel creates a transparent and high abrasion resistant silicate film on a relative soft substrate (wood or plastics) via hydrolysis and polycondensation reaction.

Potential commercial uses and users:
Powder coating industry – on non-conductive substrates such as wood (MDF) and plastics.

Advantages:
The emulsion of the present invention is based on a “green chemistry” approach to formulate an environmentally friendly, aqueous (solvent-free) conductive sol-gel emulsion for surface treatment of low-conductivity surfaces. The film created by the conductive emulsion adheres extremely well to the surface of the object and provides the following beneficial characteristics: good wetting of the substrate, creates a uniformly conductive surface for evenly attracting powder particles and a smooth and hard film highly resistant to scratches.
