Inorganic Zinc-Rich Primer (2K) – Two-component ethyl silicate zinc-rich primer for cathodic protection of blast-cleaned steel.
General-purpose use for bridges, towers, gas holders, oil tanks, oil/gas pipelines, and industrial steel structures.
High zinc dust content with stated water/oil/media resistance and welding/cutting resistance.
Sa 3 surface preparation (not lower than Sa 2.5); touch dry 10 min at 25°C, RH 70–85%.
Overview
Two-component inorganic zinc-rich primer based on ethyl silicate resin and zinc dust.
It is described as having high zinc dust content with excellent corrosion resistance and cathodic protection, heat resistance, good welding/cutting resistance, and good compatibility with other coating types; it also states excellent resistance to water, oil, and media.
Composition
Ethyl silicate resin, zinc dust, toughening agent, anti-settling agent, solvent; supplied as Part A and Part B.
Typical uses
Long-term anti-corrosion primer for blast-cleaned steel; stated to withstand up to 400°C on properly prepared steel.
Typically used with epoxy coatings for corrosion protection; stated as a general-purpose long-term anti-corrosion primer for bridges, towers, gas holders, oil tanks, oil/gas pipelines, and industrial steel structures.
