Introduction:

This product adopts phenolic epoxy resin, and for the first time to join the independent research and development of conductive polymer and conductive materials, gather doped conductive and intrinsic conduction advantages as a whole, is specially designed for conductive heavy-duty powder coatings, the coating surface resistance value below 105 , can effectively eliminate the electrostatic accumulation on gas drainage pipeline, to avoid static electricity spark, improve safety performance. High reactivity, strong adhesive force, high crosslinking density, the coating has excellent chemical resistance, solvent resistance, resistance to cathodic stripping, excellent flexibility, impact resistance and other properties.

Feature:

1. Very good adhesion with the substrate.

2. Independent research and development materials, integrating intrinsic conduction and doped conductive as a whole.

3. good electrical conductivity and coating surface resistance up to 105, effectively eliminate the surface charge accumulation.

4. Coatings and metal interface form a negative electric field shielding electron transfer, protect the metal

5. The coating has excellent high temperature cathodic disbonding resistance.

6. Low melting temperature, high reactivity, high curing completion rate, good mechanical performance.

7. Add the accord with flame retardants, have certain flame retardant effect

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.
