Single-Layer Epoxy Anti-Corrosion Powder Coating (External Coating)
Product Introduction:
This product is formulated using epoxy resin, functional curing agents, and a meticulous design. It features high reactivity, strong adhesion, high cross-link density, and excellent resistance to chemicals, solvents, and cathodic disbondment. The coating also offers superior flexibility, impact resistance, and other performance characteristics.
Product Features:
Excellent adhesion to the substrate.
Smooth surface with high gloss.
Strong resistance to permeation and corrosion.
High surface hardness and dense coating, providing good resistance to plant root penetration.
Excellent resistance to high-temperature cathodic disbondment.
Low melting temperature, high reactivity, and high curing completion rate.

Compliance Standard:
SY/T 0315-2005
Application Fields:
Municipal, water supply, drainage, sewage, circulating water, chemical, power, and other pipeline applications.
Application Process:
Electrostatic spraying.
Precautions:
The steel pipe surface should be free of oil and moisture; the surface treatment quality should reach Sa2 1/2 level (GB/T 8923); the anchor pattern depth should be 50-90 mm; dust and abrasives on the steel pipe surface should be blown clean; preheating temperature should be controlled between 180-230°C.
The product should be stored in a well-ventilated, dry indoor environment with a temperature below 30°C, away from heat sources, corrosive chemicals, and chemical solvents, and protected from strong light exposure; the stacking height should not exceed four layers; avoid long-term pressure, ensure the packaging box is sealed to prevent caking and moisture, which can affect fluidization performance.
