"Paint-to-powder" - the application of powder coatings in automotive wheels

China Paint Online News Information
With the country's
VOC
more stringent control, the new paint coating line is not approved, water-based paint process still has many difficulties, so "paint-to-powder" is becoming more industry coating application consensus.this issue we talk about the hub coating process in the auto parts industry. It is not difficult to find that more and more hub enterprises are also moving from paint
"powder coating" of the united states.Hub Powder Coating Process
The complete process of hub powder spraying can be divided into the following main links:

, and the coating efficiency increased and the cost decreased.in some special metal colors, due to the different coating manufacturing process, metal powder coatings show better inter-layer adhesion and compatibility than water-based paint, more advantages.
with the rapid development of powder technology, more environmentally friendly special metal effects have been realized. For example, the emergence of imitation chromium powder coatings can be used in car wheels instead of environmentally friendly polishing processes.

1
, better concealability the surface of aluminum alloy wheels, mostly rough casting surface. The powder, which is solvent-free
good "fill-in", is applied to the first coating of the hub to mask surface defects.
2
, better resistance to stonebecause of solvent-free, powder coating is not easy to hang, it is easy to reach
"single-layer high-film thickness", compared to the complex multi-coated liquid paint process, single-layer powder primer, showing better resistance to stone strike performance.

, excellent surface performance powder varnish, paint film gloss and fullness, corrosion resistance, etc. are better than liquid varnish.(see full picture news from China Coatings Online)"Paint-to-powder" - powder coatings in the application of automotive
