Epoxy Anti-rust Primer

Performance & Uses

An anti-corrosive primer based on epoxy resin and polyamide, formulated with zinc phosphate and aluminum phosphate as the primary anti-corrosive pigments.

  • Fast drying.

  • Excellent adhesion, abrasion resistance, and impact resistance.

  • Outstanding anti-corrosion performance.

  • Compatible with most anti-corrosive primers and topcoats.

Designed for heavy-duty corrosion protection of machinery, bridges, and steel structures.

Drying Time & Overcoating Interval

Substrate Temp. (∘C) Surface Dry (min) Hard Dry (h) Min. Overcoating (h) Max. Overcoating (months)
10 30 24 10 6
23 15 16 6 6
30 10 10 4 6

Surface Preparation

Blast cleaning to Sa2.5 standard.

Application Conditions

The application temperature range is 10–$30^\circ\text{C}$, with relative humidity (RH) below 85%. The substrate surface temperature must be at least $3^\circ\text{C}$ above the dew point, and both temperature and humidity should be measured in the vicinity of the substrate. Application is not recommended when the substrate surface temperature exceeds $40^\circ\text{C}$. Do not apply paint during adverse weather conditions such as rain, snow, heavy winds, or sandstorms.

Subsequent Coating System

  • Subsequent Coat: High-build epoxy micaceous iron oxide (MIO) primer, chlorinated rubber topcoat, or acrylic polyurethane topcoat.

Packaging Specifications

  • Base (Part A): 30 kg

  • Curing Agent (Part B): 3 kg

Storage

This product must be stored in a cool, dry, and well-ventilated indoor warehouse. The shelf life is one year under normal room temperature conditions.

Safety

All sources of ignition are strictly prohibited at the paint mixing and application sites, and good ventilation must be maintained. Application personnel must wear protective equipment to prevent inhalation of paint mist and contact with eyes or skin. In case of skin contact, wash immediately with soap and water. In case of eye contact, rinse immediately with plenty of fresh water and seek medical attention.

Disclaimer

  • The protective performance of any coating depends largely on the application process. Application factors such as surface preparation and dry film thickness will directly impact the service life of the coating system. Users must ensure compliance with the specified application conditions when using this product.
