PLSX-02 Waterborne Rust Conversion Primer

Overview
Waterborne rust conversion primer that chemically converts rust into part of the coating film.​

Composition
Special copolymer emulsion with functional additives and rust converter; water as thinner; fully dry film is blue-purple or black.​

Typical uses
Rust-conversion pretreatment for rusted metal substrates of tanks, bridges, pipelines, brackets, automotive parts, etc., forming an integral anti-rust coating by reacting with rust.​

Technical data (typical)

• Appearance: milky white or brown uniform liquid.​

• Density: 1.05 kg/L.​

• Theoretical consumption: 0.1 kg/m² at 40 µm DFT (loss not included).​

• Drying time (25°C): surface dry 30 min; hard dry 24 h.​

Application data (25°C)

• Application methods: spray, brush, roller.​

• Thinner: clean water, ≤5%.​

• Number of coats: 1–2 depending on rust level.​

• Recoat rules: if a second rust-conversion coat is needed, apply within 10 min after first coat; after completion, minimum 24 h before applying subsequent intermediate or topcoats.​

Surface preparation
Use water jet, wire brush, or power tools to remove loose rust, oil, and other non-adherent matter; minimum St1–St2.​

System compatibility / packing / storage

• Construction conditions: ambient 5–35°C; not suitable in rain, fog, snow, or when RH ≥85%.​

• Storage: dry, cool, ventilated; temperature 5–35°C; avoid strong sunlight, severe cold, and rain.​
