Application Area: Special for municipal drinking water pipe
Applicable process: Electrostatic spraying and dip coating, etc
Notes:
# # 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 180230.
# 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.
# 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.
# Shall not be used mixed with other anticorrosive powder coatings and recycling power, when the color change, thoroughly clean spraying equipment, to ensure security of drinking water quality conform to the hygiene standards
