Supplier typeThe supplier is identified as a China-based limited company and trading company, established in 2023, with eight employees. Its listed scope covers sales of chemicals, coatings, hardware, electrical equipment, building materials, and related technical services, with some mechanical/electrical equipment manufacturing also stated.

After-Sales capabilityThe supplier states that engineers can recommend products and configure solutions when customers provide field-use information. However, it has no written procedures or records for service-capability assessment, corrective and preventive actions, or effective complaint handling, indicating a documented service-management deficiency.

R&D capabilityThe company describes itself as specializing in epoxy-resin R&D, production, sales, and service, and reports customization capabilities. Nevertheless, it states that no new products were launched in the past year and that it is not a professional technical supplier, so current innovation output is not demonstrated.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also states that engineers can recommend products and configure solutions for specific floor-application needs based on customer field information.

Product Q&A

Q:Q1: What is a zinc rich primer and how does it protect steel?

A: A zinc rich primer contains high zinc dust content that makes the coating conductive, providing cathodic protection to the steel substrate - if the film is scratched, the zinc sacrifices itself instead of the steel. This is stronger protection than conventional organic primers. It is also called zinc rich coating or zinc rich paint.

Q:Q2: Can it be applied before welding?

A: Yes. This primer can be used as a shop primer. At 15-25 microns DFT it does not affect welding performance, so parts can be pre-coated in the workshop and welded on site. For heavy protection systems apply 30-70 microns DFT per coat.

Q:Q3: What topcoats can be applied over this zinc rich primer?

A: It bonds well to general purpose epoxy coatings, acrylic polyurethane topcoat, and epoxy mid coats such as the epoxy micaceous iron oxide mid coat (EC300). Minimum recoat interval is 24 hours at 20C. Surface must be bare steel to Sa 2.5 (30-70 microns) or ST3.
