PLSX-21 Waterborne Alkyd Enamel Coating

Overview
Waterborne alkyd enamel coating for outdoor steel structures and equipment where gloss, corrosion resistance, and adhesion are required.
Film focuses on fullness and gloss with good adhesion and corrosion resistance on scaffolding, steel frames, and fences.

Composition
Waterborne alkyd resin with waterborne pigments, fillers, and special additives; single-component waterborne system using water as thinner.

Typical uses
Protective and decorative coating for scaffolding, plant steel structures, outdoor steel components, machinery, metal fences, and other steel products.
