In the use of machinery and equipment, the longer exposure time in the air, the outer surface of its surface is susceptible to oxidation by air, such as ship unloader, the protection of its anti-corrosion layer can not be ignored.

The thickness of the anticorrosion coating is directly related to the corrosion prevention effect. Without sufficient thickness, the corrosion resistance of the coating is unreliable, and at the same time, the coating of the same thickness, multi pass coating, its corrosion resistance and even mechanical properties are better than single layer. Combined with the actual, general primer coating, two road, a middle painted, and painted one or two road.

Fill putty for steel structure weld, sag, uneven parts, then use the oily polishing putty leveling or repairing putty. After completely dry, polish with 400#-600# sand paper and enter the next process.

Primer Description: epoxy zinc rich primer consists of 4 components: varnish, zinc powder, curing agent and thinner. Before the light oil and zinc powder by weight under 1:3 uniform mixing, adding curing agent is about 12%, about 12% of the diluent and mix thoroughly, then brush or spray. The prepared paint should be used up in 8-10 hours. In general, 25-35 m per membrane thickness, painted 2-3 times, the first dry before you can paint it again. Coating time of 24 hours, after work, with 400#-600# sandpaper polished.
