If you are coating parts that will be permanently outdoors and therefore require good toughness and durability, then consider super-durable polyester over standard durability.
The SD Series of Architectural Powder Coatings has been specifically formulated to provide a long-lasting, durable exterior finish. Harsh UV light, high temperature, and humidity have a detrimental effect on the coating. The SD Series powder coatings have been developed to withstand such demanding conditions. The powders are subjected to extensive internal and external tests for color stability, gloss retention, and adhesion to the substrate, both in the laboratory and under harsh climatic conditions (Florida, USA).
The SD Series offers three types of powders, allowing the architect to select the most suitable powder based on budget, application, and durability requirements. All three grades can be formulated to meet customer-specific requirements that vary in color, gloss, texture, and metallic effect.
Kalpatrucoat offers a limited-time warranty on the SD Series when used as intended. These specifications provide guidelines for product selection, application, and maintenance and are available from Kalpatrucoat.
