Introduction:???
This product adopts phenolic epoxy resin, and for the first timeto join the independent research and development of conductivepolymer and conductive materials, gather doped conductive andintrinsic conduction advantages as a whole, is specially designedfor conductive heavy-duty powder coatings, the coating surfaceresistance value below 105 , can effectively eliminate theelectrostatic accumulation on gas drainage pipeline, to avoidstatic electricity spark, improve safety performance. Highreactivity, strong adhesive force, high crosslinking density, thecoating has excellent chemical resistance, solvent resistance,resistance to cathodic stripping, excellent flexibility, impactresistance and other properties.
feature???
- Very good adhesion with the substrate.
- Independent research and development materials, integratingintrinsic conduction and doped conductive as a whole.
- good electrical conductivity and coating surface resistance upto 105, effectively eliminate the surface charge accumulation.
- Coatings and metal interface form a negative electric fieldshielding electron transfer, protect the metal
- The coating has excellent high temperature cathodic disbondingresistance.
- Low melting temperature, high reactivity, high curingcompletion rate, good mechanical performance.
- Add the accord with flame retardants, have certain flameretardant effect

Notes:
- Steel surface should be no oil and water, surface qualityshould reach Sa2 1/2 level (GB/T8923), anchor pattern depth50-90mm, clean dust and abrasive attached to the steel surface,preheat, control temperature in 180???230???.
- Product should be stored in ventilated, dry, indoor temperaturebelow 30 ???, away from heat, corrosive chemicals and chemicalsolvents, avoid bright light, the maximum stack height should notexceed 4 layers, avoid prolonged pressure, ensure airtight box. Incase the clot and damp affects the fluidization performance.
- To best curing epoxy coating, best anti-corrosion, suggestedpreheating tube surface temperature in more than 200???, in orderto better improve the curing completion.
