B04-2 Acrylic Enamel Coating

Overview
Acrylic enamel coating for steel substrates on vehicles, machinery, and steel structures where high hardness and weatherability are required.
Performance focus: fast drying, adhesion, hardness, long-term color/gloss retention, and salt spray / damp-heat resistance.

Composition
Acrylic resin with weather-resistant pigments, additives, and solvent.

Typical uses
Surface decoration for automobiles, construction machinery, mining machinery, agricultural machinery, metal products, and steel structures.

Technical data (typical)

• Appearance: various colors.

• Theoretical consumption: 0.10 kg/m² at 25 µm DFT (loss not included).

• Drying time (25℃): surface dry ≤0.5 h; hard dry ≤3 h.

• Salt water resistance: 60 h, no blistering or peeling; slight color change allowed.

Application data (25°C)

• Mixing ratio: single-pack.

• Application methods: air spray, high-pressure airless spray, electrostatic spray.

• Thinner: acrylic thinner.

• Recoat interval: min 2 h; max unlimited.

• Recommended primers: acrylic primer; high-chlorinated polyethylene primer; chlorosulfonated polyethylene primer; epoxy primer.

• Application conditions: suitable for low-temperature application; do not apply in rain/fog/snow or RH >85%; avoid strong sunlight in hot seasons.

Surface preparation
Over primer: surfaces must be clean, dry, and free of contamination.
As first primer: blast-clean to Sa 2.5 or power-tool clean to St 3; surface profile 30–75 µm.

System compatibility / packing / storage

• Compatibility: compatible over acrylic, high-chlorinated polyethylene, chlorosulfonated polyethylene, or epoxy primers.

• Packing: 22 kg.

• Storage: dry, cool, ventilated warehouse; keep away from ignition and heat sources; shelf life 12 months.
