dip coating, roller coating, etc.

2. Coating Thickness - Can be adjusted between 250-450 m according to workpiece requirements.

Health and Safety:

1. This product is non-toxic and non-flammable, but please comply with the GB15607-1995 Safety Regulations forCoating Operations during use.

Precautions:

1. This product is not recommended for outdoor use of workpieces, as it may cause fading and powderingphenomena;

2. The steel pipe surface should be free from oil stains and moisture, with surface treatment quality reaching Sa21/2grade (GB/T8923). The roughness depth should ideally be 40~ 100um, and any dust or abrasive particles adhering tothe pipe surface must be thoroughly blown clean.

3. Preheating: The temperature should be controlled between 180~ 250°C and must not exceed 250°C

4. Powder products should be stored indoors in a well-ventilated, dry area with temperatures below 30°C, away fromheat sources, corrosive chemicals, and chemical solvents, and protected from strong light exposure. The maximumstacking height should not exceed five layers. Avoid prolonged pressure, ensure the packaging boxes are tightlysealed to prevent clumping and moisture absorption, which may affect fluidization performance.

5. To ensure thorough curing of the epoxy coating and maximize its anti-corrosion performance, it is recommendedto preheat the steel pipe surface temperature above 200°C, which can significantly improve the curing completionrate.
