Cold spray zinc anti-corrosion primer for replacing hot-dip or thermal-sprayed zinc.
Towers, bridges, pipelines, tanks, containers, ships.
Total zinc content 96%; surface dry 20 min.
Single-component; recoat after ≥10 h.
Overview
Single-component cold spray zinc anti-corrosion primer combining cathodic protection and barrier protection.
Composition
Ultra-fine zinc powder, special olefin resin, trace solvent.
Typical uses
Anti-corrosion for steel components such as towers, bridges, pipelines, storage tanks, containers, ships, vehicle logos, nameplates, and fences.
Used for long-term protection of new steel to replace hot-dip galvanizing, thermal spray zinc, and conventional anti-corrosion systems.
Can be used as a single-layer metal protection coating or as a primer in heavy-duty coating systems.
