TOKYO - Toyota Motor Corp. in August began phasing in an environmentally friendly paint technology at its Japanese factories.
The new technique uses a robotic paint sprayer with a cartridge-type tank that allows the use of water-based paints in electrostatic painting, which is favored for its high productivity and covering efficiency.
The new equipment allows frequent and quick changes in paint colors, while using one-tenth as much paint thinner as conventional methods to clean painting equipment.
Using the new method for the base coat applied in its Takaoka plant, Toyota has cut the solvent discharge of volatile organic compounds to 35 grams per square meter of paint coverage, compared to 64 grams per square meter previously.
Using Toyota's new metallic water-based paint with the new equipment, it is possible to generate an electrostatic charge in the paint itself.
