Characteristics and Common Supporting Facilities of Epoxy Zinc-rich Primer

Epoxy zinc-rich primer is an anti-corrosion paint architectural coating composed of epoxy resin glue and zinc powder as the main raw materials mixed with tackifier, filler, modifier, organic solvent, etc. Among them, zinc powder conforms to ASTMD520/TypeII type specification. It is mainly used in stainless steel sheet pipelines, storage tanks, steel frame structures, shipping containers, etc. Meet the anti-corrosion regulations of ambient air, marine resources, immersion in natural environment, strong acid and alkali natural environment, sand and dust natural environment, high salt natural environment, condensation natural environment, etc.

Ⅰ. The characteristics of epoxy zinc-rich primer

Epoxy zinc-rich primer has excellent anti-corrosion properties, strong adhesion, high zinc powder content in the paint layer, has cathodic protection of pipelines, excellent waterproof performance, salt spray resistance test time of more than 2000 hours, and can be welded by electric welding The film thickness is 15-20μm when electric welding is carried out, which is not easy to damage the electric welding characteristics.

Epoxy zinc-rich primers are available in a variety of models and specifications with zinc content, each with a zinc content of 30% zinc content epoxy zinc-rich primer, 50% zinc content epoxy zinc-rich primer, 60% zinc content Epoxy zinc rich primer with 70% zinc content, epoxy zinc rich primer with 70% zinc content and 80% zinc content epoxy zinc rich primer. A variety of zinc content can be selected according to the anti-corrosion regulations of FRP.

Epoxy zinc-rich primer has excellent supporting properties and can be applied with a variety of intermediate paints and paint supporting facilities.

Ⅱ. The general supporting facilities of epoxy zinc-rich primer

Epoxy zinc-rich primer is used in many industries such as steel frame structure, engineering construction exhibition hall, highway bridge steel structure, port logistics equipment, engineering machinery equipment, petrochemical storage tank, steel pipe anticorrosion, etc., and the key supporting facilities epoxy resin cloud iron intermediate paint and its anti-corrosion paint.

1. Anti-corrosion of steel structure: epoxy zinc-rich primer + epoxy resin micaceous iron intermediate paint + polyurethane paint;

2. Safety protection of highway bridge steel structure: epoxy zinc-rich primer + epoxy resin micaceous iron intermediate paint + fluorocarbon paint;

3. Decoration design of engineering and construction exhibition hall: epoxy zinc-rich primer + epoxy resin micaceous iron intermediate paint + fluorocarbon paint;

Epoxy zinc-rich primer is an anti-corrosion material with excellent component performance. The components include main paint and epoxy curing agent. Special paint thinner for supporting facilities. Epoxy zinc-rich primer is mainly used for corrosion-resistant spraying of steel frame structures. Very good maintenance.

Before the construction of the project, the main paint and epoxy curing agent should be mixed according to the ratio of 10:1, add paint thinner, use special electric mixing tools to stir well, and let it mature for 15-30 minutes to make the paint fully combined. The construction of architectural coatings must pay attention to the availability period. The epoxy zinc-rich primer is generally around 4-6 hours. The architectural coatings are used within this time to prevent condensation.
