Difficulties and solutions in the coating of water-based industrial coatings

Water-based industrial coating difficulties and solutions
cracking:
mainly occurs in water-based coatings and solvent-based coatings supporting the application of the case, late construction of water-based coatings such as solvent-based coatings, it is easy to crack phenomenon.
solution:
need to do a good job of protection when spraying solvent coatings, to avoid solvent coatings fly to water-based coatings to be sprayed.
:
water-based paint to water as a medium, when the coating surface clean and there is dirt, because the surface of water is high, easy to cause the phenomenon of shrinking holes .
measures:
thoroughly check the status of the surface to be painted, if necessary, sandpaper on the primer surface hair treatment, so that it has a certain roughness, to benefit the paint coating.
: when
is applied, it is prone to cracking when the wet film thickness exceeds 120 m.
measures:
to use multiple spraying methods, to meet the requirements, each spray interval must not be <5min, each spray film thickness control in 30 to 40 m (dry film).
water-based coatings market has great potential. And can be widely used in the automotive manufacturing industry outside the metal metal metal coating. At present, China has become the world's largest manufacturing base, these new applications are expected to have a rapid growth trend in the future.
