Technical | Methods of Coating | Electropainting (Dip)

Process	A method of application rather than a paint. Substrates are immersed in a solution and a charge applied to attract paint from solution to the substrate. Similar process to electroplating. Used mostly in production lines in high volume manufacturing especially automotive.
Strengths	Repeatable, uniform process with low unit costs.
Weaknesses	Unsuitable for jobbing, colour changes very expensive, limited range of paint types.
Durability	5 years
Cost	£5-10 per sqm
Health and Safety	Factory controlled
Environmental	Factory controlled

Technical | Methods of Coating | Electropainting (Spray)

Process	A method of application - not a paint. Liquid paint is sprayed with an electrostatic charge, causing less overspray as the paint is attracted to the job. Similar to powder coating in this respect. Solvents are still used, so the issues of liquid paints apply.
Strengths	Less overspray, less wastage. Can be done on site.
Weaknesses	Colour changes more expensive, faraday cage effects apply, limited types of paint possible to be used, solvent issues apply as all liquid paints.
Durability	Depends on the paint used.
Cost	£30 per sq m
Health and Safety	All issues of solvents, VOCs and site issues apply.
Environmental	All site applied coating issues apply. VOCs can be an issue depending on the paint used.
