PLS52-3 Aliphatic polyurethane premium topcoat Descriotion

Overview
Two-component aliphatic polyurethane premium topcoat for long-term protection and high-grade finishing on steel structures.
Provides resistance to chemical media corrosion, seawater, boiling water, oil, benzene solvents, and salt spray; designed for weathering and color retention.

Composition
Based on premium polyurethane resin, premium weather-resistant pigments, weathering extenders, solvents, and imported additives.
Cured with biuret; supplied in Part A & Part B packs.

Typical uses
For long-term protection and high-grade finishing on steel structures in various environments.
Typical applications include vehicles, bridges, steel towers, TV towers, construction machinery, marine and port facilities.
