Our for zinc flake coating surface hardness is low, defects in the
coating and acid and alkali resistant, draw lessons from domestic
formula technology, high-quality raw materials research and
production of JH-9320 zinc flake coating special self dry coating
liquid, both increase of zinc flake coating on surface hardness,
acid and alkali resistance, and can improve the anticorrosion
performance of the coating and with zinc flake coating affinity
good adhesion.
The main ingredient is water-base inorganic silica , mixed with
corrosion protection assistant.The product cost is low.

Instructions and attention:
Dip coating,Spray coating etc.
It should be stirred fully befor usage; distilled water or
deionized water can be used to adjust viscosity ;Operating
viscosity:30-60s.
When the environment humidity higher than 85%,can add certain
industrial alcohol to adjust viscosity
Curing condition: 80℃/10min+140℃/30min
Cleaning appliance: running water can be used
Avoid acid substances, or polymerization and deterioration will
happen.
This product can be used alone,the coated surface request oil
free,dust free and dry,the better make pre-treatment of
degreasing,derusting,and phosphating.
