polyester powder coating

All apropos structures are finished using polyester powder in accordance with BS6496:1984 Specification for Powder Organic Coatings for Application and Stoving to Aluminium Alloy. Polyester powder coating is a superior surface colour treatment. Coatings are based on polyester resin which is cured at high temperature to form a smooth durable surface. The thickness of the apropos coating is between 40 and 80 microns and adhesion is ensured by strict adherence to pre treatment regimes in respect of cleaning and etch priming in particular. apropos offers a standard range of colours (RAL’s) but will deviate from that range (for a premium) provided the chosen RAL is stable and appropriate for external use.
