Introduction
Anti-Graffiti Powder Coating is a thermosetting polyurethane powder coating formulated with saturated polyester resin and an isocyanate curing agent. It is designed to provide weather resistance, corrosion protection, chemical and solvent resistance, and scratch resistance. It is suitable for metal products that require durable surface protection and easier graffiti removal, subject to the specific formulation and verified performance.
Key Features
Weather Resistance
Designed for outdoor exposure, with performance dependent on the formulation and service environment.
Corrosion Protection
Provides a protective coating barrier for suitable metal substrates.
Chemical Resistance
Formulated to resist selected chemicals and solvents under specified test conditions.
Scratch Resistance
Provides a hard coating film for durable surface protection.
