Description
Introduction: This double epoxy powder adopts many kinds of function of epoxy resin, curing agent, both bottom coating and other anti-corrosion epoxy powder coating have excellent anticorrosion performance, external coating stand out protective properties on the basis of corrosion, can be widely used in more stringent corrosion environment, especially especially traversing pipeline for mountains, rivers and hills region.
Feature:
1. Very good adhesion with the substrate and epoxy.
2. Strong permeability and corrosion resistance
3. The coating has excellent high temperature cathodic disbonding resistance.
4. High surface hardness, strong coating density, good ability to resist plant roots puncture

Carried Standard: Q/CNPC 38-2002
Application Area: Corrosion environment is complex, especially traversing pipeline for mountains, rivers and hills region.
Applicable process: Electrostatic 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
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.
