Double Epoxy Anticorrosive Powder Coating

product description:
The double epoxy powder system using a variety of epoxy functional curing agent, well-designed, undercoat and, like other anti-corrosion epoxy powder coating has excellent corrosion resistance, corrosion resistance while maintaining the outer coating on the basis of more highlighting the protective properties, it can be widely used anti-corrosion requirements more demanding environments, especially through the pipeline mountains, rivers, hilly areas.
Product Features:
1, between the bottom and the substrate, between epoxy layer has very good adhesion.
2. Has a strong anti-infiltration and corrosion resistance.
3. The outer coating of high hardness, dense coating is strong, scratch, has good resistance to puncture plant roots.
The coating has excellent resistance to high temperature cathode stripping ability.
Application:
Antiseptic environment is complex, especially in the mountains, rivers, hilly area through pipeline

Executive Standard: Q / CNPC 38-2002
Construction Description:
1, the spraying conditions: electrostatic spraying, dipping, fluidized bed
2, pre-treatment: steel surface should be free of oil and water; surface treatment quality should reach Sa2 1/2 class (GB / T8923); anchor pattern depth appropriate for the 50-90mm; steel surface adhesion of dust and abrasive material should be purged.
3, preheating temperature: pipe surface temperature should be controlled at 180-230 ℃
4, curing temperature: Pipe surface temperature should reach 200 ° / 10 min or 180 ° / 15 minutes
5, test packaging: steel surface quality can check and repair the leak at 80 ° or less.
Powder storage:
The product should be stored in ventilated, dry, indoor temperature below 27 ℃, away from the heat source, corrosive chemicals and chemical solvents, to avoid glare; maximum stack height easily over four layers; avoid prolonged pressure, to ensure airtight containers, in order to avoid clumping and moisture, affect the flow of the performance.
Health and safety
The powder coating does not contain toxic substances, baking and no toxic gases. But in the course of inhalation of dust should be avoided, the operator should wear dust masks, glasses, protective clothing and other protective equipment, and to minimize prolonged contact with the skin, attached to dust the skin, wash with soap.
