Epoxy Anti-Corrosion Powder Coating for Steel Reinforcement

Product Introduction:

This product is a thermosetting epoxy-modified heavy-duty anti-corrosion powder coating specially designed forsteel reinforcement anti-corrosion coatings. It featuresexcellentreactivity and adhesion, superior toughness andflexibility, as well asoutstandingchemical resistance, solvent resistance, cathodic disbondment resistance, impact

resistance, and other properties.

Product Applications:

Widely applicable for corrosion protection of steel reinforcement in bridges, ports, airports, buildings, basements,high-speed railways, etc.

Product Features:

1. Exhibitsexcellentadhesion to substrates;

2. The coating is dense, continuous, glossy, impermeable, and has few leakage points;3. The coating exhibits excellent cathodic disbondment resistance and high electrical insulation;4. The coating demonstrates high bond strength with concrete;

5. It has good toughness and does not crack when bent.

6. Low melting temperature, high reactivity, high curing completion rate, and excellent mechanical properties;

7. Strong versatility with low powder consumption;

8. Reduces or avoids wire drawing phenomenon in powder coating of steel bars.

Execution Standards:

JC3042-1997 "Epoxy Resin Coated Reinforcing Steel Bars; GB/T25826-2010 "Epoxy-Coated Steel Bars for ReinforcedConcrete'

Curing Conditions:

Curing temperature: 210~250°C/3~1.5min

Note: The recommended curing conditions refer to the workpiece temperature, and temperature deviations mayaffect the performance of the coating or prevent it from being fully realized.

Construction parameters:

1. Applicable Equipment Processes such as triboelectric spraying, corona electrostatic spraying, dip coating, etc.

2. Coating Thickness Can be adjusted between 120~250um according to workpiece requirements.

Health and Safety:

1. This product is non-toxic and non-combustible, but please comply with the GB15607-1995 Safety Regulations forCoating Operations when using it.

Precautions:

1. This product is not recommended for outdoor use on workpieces, as it may lead to fading, chalking, and otherphenomena.

2. The surface oxide scale of the reinforcement is completely removed, exposing the original metal color; the surfaceroughness treatment quality meets the standard and should be 50-70 um; the rust removal grade reaches Sa21/2, withno chloride or other attachments on the reinforcement surface.

3. Preheating: Temperature should be controlled between 220~ 245°C;

4. Powder products should be stored in a well-ventilated, dry indoor environment with temperatures below 27°C,away from heat sources, corrosive chemicals, and chemical solvents, avoiding strong light exposure; the maximumstacking height should not exceed 5 layers; avoid prolonged pressure to ensure the packaging remains sealed.preventing clumping and moisture absorption which could affect fluidization performance;

5. Due to the product's high reactivity, the recommended storage period is up to three months at 27°C for optimalperformance. If used beyond this period, prior verification of its properties is necessary.
