Epoxy Zinc-Rich Primer

Composition Characteristics:

This paint is a two-component heavy-duty anti-corrosion primer formulated with zinc powder, where Component A consists of epoxy resin as the base material mixed with ultrafine zinc powder and other additives, and Component B is a curing agent composed of polyamide resin. It features air drying at room temperature and minimal zinc sedimentation.

Functionality and Applications:

With a high zinc content in the coating, this primer provides cathodic protection, excellent adhesion, and outstanding water resistance and anti-rust properties. It also dries quickly and is oil-resistant, making it compatible with most anti-rust paints and topcoats. A coating thickness of around 20 microns does not affect welding performance. It can be used as a maintenance primer for steel plates after shot blasting or sandblasting in shipbuilding and bridge construction, as well as an anti-corrosion coating for steel structures.

Color: Gray

Flash Point: Approximately 27°C

Basic Parameters: Drying time (at 25°C and 65% relative humidity) - Surface dry: 0.5 hours, Hard dry: 24 hours, Full cure: 7 days.

Coating Compatibility and Application:

1. Before application, mix Components A and B in the specified ratio, stir thoroughly, and allow to mature for half an hour before use.

Mixing ratio: Component A : Component B = 10:1. Pot life after mixing (at 25°C): 8 hours.

2、This paint can be applied by brushing, rolling, or high-pressure airless spraying.

3、Usage parameters: As a maintenance primer: 80 g/m2, dry film thickness 20 microns. As an anti-rust paint: approximately 270 g/m2, dry film thickness 70 microns.

4、Thinner: Epoxy thinner.

5、Metal surface preparation: For optimal metal protection, steel surfaces must be treated by shot blasting or sandblasting to remove scale, rust, oil, and other contaminants, achieving Swedish rust removal standard Sa2.5 before coating.

6、Compatible topcoats: Epoxy micaecous iron oxide heavy-duty primer, epoxy asphalt series coatings, chlorinated rubber coatings.

7、Curing reaction slows down when the application environment is below 10°C.

Packaging Specifications: Epoxy zinc-rich primer paste (Component A) 25 kg/drum, Curing agent (Component B) 2.5 kg/drum.

Shelf Life: One year
