Carried Standar: GB/T 5135.20-2010; CJ/T 120-2008

Application Area: Fire water supply pipeline anticorrosion coating inside and outside.

Applicable process: spray coating and dip coating

Notes:

1. Steel surface should be no oil and water, surface quality should reach Sa2 1/2 level (GB/T8923), anchor pattern depth 50-90mm, clean dust and abrasive attached to the steel surface, preheat, control temperature in 180－230℃.

2. Product should be stored in ventilated, dry, indoor temperature below 30 ℃, away from heat, corrosive chemicals and chemical solvents, avoid bright light, the maximum stack height should not exceed 4 layers, avoid prolonged pressure, ensure airtight box. In case the clot and damp affects the fluidization performance.

3. To best curing epoxy coating, best anti-corrosion, suggested preheating tube surface temperature in more than 200℃, in order to better improve the curing completion.
