Epoxy rust-inhibiting primer

Composition   Epoxy rust-inhibiting primer A component consists of epoxy resin, rust-inhibiting pigments, additives, solvents, etc., while the B component is the hardener.

Performance  The coating forms a stable complex with iron, thus offering excellent stability against rust and a long-lasting corrosion-resistant effect. It adapts well to both rusty and non-rusty steel surfaces, boasts good mechanical properties of the film, and has strong adhesion.

Usage  Epoxy rust-inhibiting primer is suitable for repairing and protecting rusted steel surfaces and rusted paint film surfaces. Generally, rusted steel requires sandblasting or grinding before painting, which is time-consuming and costly. Using rust-inhibiting paint can solve these issues. Epoxy rust-inhibiting coating can be directly applied to steel surfaces with rust (rust layer below 60 micrometers) and steel surfaces that have been simply de-rusted for corrosion protection.

Technical Specifications

Complementary System

Epoxy anti-rust primers are used in a wide range of applications such as steel structures, architectural venues, bridge steel frameworks, port and terminal facilities, construction machinery, petrochemical storage tanks, pipeline corrosion protection, and more. They are mainly paired with epoxy iron oxide intermediate coatings and corrosion-resistant topcoats.

Construction Method

1. Base Material Processing

It's necessary to simply remove rust, flaking paint, and oil污 from the coated metal surface.

2. Mixed

By weight ratio (as indicated on product packaging)

Mix by slowly adding the hardener while continuously stirring the main agent to ensure thorough and even mixing.

Mixed paint is aged (23±2℃) for 30 minutes, then filtered through a 60-80 mesh sieve and transferred to another container for later use.

The mixed paint has a shelf life of 3 hours; please schedule usage according to the progress of the application.

3. Construction Conditions

The coating operation should be carried out as soon as possible after the substrate treatment, generally not exceeding 6 hours. The surface temperature of the substrate and the ambient temperature should generally not be below 10°C, with the surface temperature at least 5°C above the dew point, and the relative humidity of the air should not exceed 75%.

4. Coating Methods

This paint can be applied using brush painting, airless spraying, and air-assisted spraying methods.

5. Dilute

Generally, paint requires a compatible thinner to adjust viscosity and clean tools.

6. Coating Interval

One-component paint is ready for subsequent coating after drying. For two-component paint, it is recommended to leave the following curing interval before coating:
