Different of electrophoretic paint and regular paint of hardware-A

Hardware electrophoresis paint and ordinary paint in the process principle, coating effect, environmental performance, application scenarios, there are significant differences, the following is a specific analysis:

First, the process principle and operation mode

Electrophoretic paint

Process principle

based on electrophoretic coating technology, using electric field to make charged paint particles deposited on the surface of the workpiece to form a uniform coating.

Operation mode

the workpiece needs to be immersed in the electrophoresis tank liquid, and the automated coating is realized through DC electric field, which is complicated but controllable.

Ordinary Paint

Process Principle

The paint is covered on the surface of the hardware by physical means such as spraying or brushing.

Operation mode

rely on manual or simple equipment to complete, low threshold for operation but easily affected by human factors.

Second, the coating effect and performance differences

Coating uniformity

Electrophoretic paint

the coating thickness is uniform, suitable for complex structure workpieces, good coverage of edges, gaps and other parts.

Ordinary paint

the operation methods will coating thickness is easily affected by , and the complex structure workpiece is prone to problems such as hanging and uneven thickness.

Corrosion resistance

Electrophoretic paint

Dense coating, excellent resistance to salt spray and chemicals, suitable for harsh environments.

Ordinary paint

weak corrosion resistance, need to cooperate with primer or increase the thickness of coating to enhance the protective ability.

Adhesion

Electrophoretic paint

strong adhesion to metal substrate, outstanding impact resistance and bending resistance.

Ordinary paint

adhesion is greatly affected by the treatment of substrate and construction conditions, and the surface cleanliness needs to be strictly controlled.

Third.environmental protection and safety performance

Electrophoretic paint

Environmental protection

water as solvent, low VOCs emission, in line with environmental regulations.

Safety

no flammable and explosive risk, safe and controllable production environment.

Ordinary Paint

Environmental protection

solvent-based paints have high VOCs content and need equip with waste gas treatment equipment.

Safety

flammable and explosive, need to strictly manage the storage and use environment.
