Water-based inorganic zinc-rich primer VS water-based epoxy zinc-rich primer

In the anti-corrosion coating system of steel structure, the role of zinc-rich primer is very important.

●From the perspective of ingredients

The water-based inorganic zinc-rich primer is a heavy-duty anti-corrosion coating made of inorganic silicate as the base material, zinc powder as the main anti-rust pigment, and various fillers and additives

The water-based epoxy zinc-rich primer is a two-component coating with water as the diluent, composed of zinc powder, water-based epoxy emulsion, water-based special fillers, special pigments, and polyamide water-based dispersion curing agent

●Application

The water-based inorganic zinc-rich primer can be applied to oil tanks, oil tanks, solvent tanks, ballast water tanks, marine steel structures with harsh environments and conditions, bridges, chimneys, etc.

The water-based epoxy zinc-rich primer is used as a primer product and is suitable for the coating of projects with mild to high anti-corrosion requirements

●Performance

The water-based inorganic zinc-rich primer has excellent corrosion resistance, salt spray resistance above 1000H, water as a solvent, no fire hazard, excellent wear resistance and heat resistance, and usually can withstand high temperatures of 400°C

The water-based epoxy zinc-rich primer uses water as a diluent, which has no pollution to the environment and no harm to health.

●Supporting

The water-based inorganic zinc-rich primer can be matched with acrylic polyurethane, epoxy paint and vinyl paint except that it cannot be matched with oil paint

Water-based epoxy zinc-rich primer generally adopts these supporting systems: water-based epoxy zinc-rich primer + water-based epoxy mica intermediate paint + water-based fluorocarbon paint (applicable to all kinds of steel structure projects, including bridges, workshops, buildings, storage Tanks, ports, etc.
