1 General description

In view of the defect that dacromet coatings surface hardness is low, and no acid and alkali resistant,we learn from the advanced technology formulation,develop and produce JH-9323 dacromet coating, water-based dacromet coating,can not only increase the dacromet coatings surface hardness,acid and alkali resistance,and can improve the anti-corrosion performance of the coating (SST≥1500h).Have good adhesion with dacromet coating,and has many colors. Coating process is similar to dacromet coating,your first choice of dacromet top coat.

2 Perfomance charcteisic

The coating layer is smooth, weak acid and alkali resistant, can be adjusted to any colour with paint.

4 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.
