Primer is the first coat of an anti-corrosion coating system and determines the adhesion and anti-rust life of the entire system. Coating failures on steel structures, storage tanks, pipes and bridges are mostly not caused by topcoat failure, but by incorrect primer selection or improper application. Common types include epoxy zinc-rich primer (sacrificial anode protection, suitable for severe corrosive environments), inorganic zinc silicate primer (temperature and solvent resistance, suitable for high-temperature areas and storage tank interiors), epoxy micaceous iron oxide primer (strong barrier properties, often used as an intermediate coat with zinc-rich primer), and various anti-rust primers (cost-effective solutions for mild corrosive environments). Selection mainly depends on three things: substrate and surface preparation grade, required anti-corrosion service life, and the type of subsequent topcoat—primer and topcoat must be compatible, otherwise intercoat peeling occurs. This page summarizes original manufacturer technical data for primers from various brands by model, including volume solids, theoretical spreading rate, recommended dry film thickness, drying time and compatibility instructions, available for online viewing or the original manufacturer TDS requested for verification.

This page compiles original-factory technical data sheets by tag. The same model may appear under several tags at once (for example, a water-borne epoxy primer belongs to "water-borne", "epoxy" and "primer"), the more entry points a model has, the more easily it is found by search habits.
