JH-9320 strong hardness with dry, acid and alkali zinc chromate coating

1 General description

Our for Dacromet 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 Dacromet special self dry coating liquid, both increase of Dacromet coating on surface hardness, acid and alkali resistance, and can improve the anticorrosion performance of the coating and with Dacromet coating affinity good adhesion.

The main ingredient is water-base inorganic silica , mixed with corrosion protection assistant.The product cost is low.

2 Perfomance charcteisic


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