Import Epoxy Zinc Antirust Primer — Buy in Bulk from Supplier in China

Epoxy Zinc Antirust Primer is a two-component coating designed for direct application on steel and iron substrates to prevent rust formation through cathodic protection. The product contains a minimum of 70% zinc dust by weight in the dry film, as confirmed by the supplier's technical data. It exhibits a dry film thickness range of 40 to 60 microns per coat and achieves a pencil hardness of 2H after curing. Adhesion to blasted steel meets ASTM D4541 standards with pull-off values exceeding 5 MPa.

The formulation relies on epoxy resin systems with zinc phosphate as a secondary inhibitor, providing long-term barrier protection. This primer is typically applied over grit-blasted surfaces with a profile of 50 to 75 microns. It is not intended for direct UV exposure and must be topcoated within 7 days to prevent amine blush. The solvent content is low, with less than 150 g/L VOC, aligning with industrial environmental guidelines for coating applications.

This primer is commonly used in infrastructure projects including bridges, transmission towers, offshore platforms, and heavy machinery. Buyers include engineering contractors, shipbuilders, and industrial maintenance teams sourcing bulk quantities for field application. Packaging is available in 20 kg kits (resin and hardener), with a minimum order quantity of 100 kg. Lead time is typically 15 to 20 days after order confirmation, and delivery terms are FOB Jiangmen Port.
