PVDF Coating Aluminum Extrusion Profiles

PVDF-coated aluminum extrusion profiles, renowned for their superior weather resistance, UV protection, corrosion resistance, and long-term color retention, are widely applied in high-demand scenarios across multiple industries. In the architectural field, they are the preferred choice for exterior curtain walls, roofing systems, sunshades, and high-end door/window frames, especially suitable for harsh environments such as coastal areas, high-altitude regions, and industrial zones. In the transportation industry, they are used in automotive exterior trim, rail transit carriage components, and marine vessel structures, thanks to their excellent resistance to salt spray and mechanical impact.

Advantages

PVDF belongs to a category of fluorocarbon resins. PVDF stands for polyvinylidene fluoride. Polyvinylidene fluoride coatings contain at least 70% Kynar500® or Hylar5000® resin and comply with AAMA 2605 or GB/T5237.5 standards. This resin is widely used in architectural coatings for its good weather-resistant properties.

Color Range

A wide variety of colors and finishes are available for PVDF-coated aluminum extrusion profiles.
PVDF Coating Process

The two-coat system consists of a primer and a solid or pearlescent topcoat of choice by the engineer. The coating should be applied to a pretreated aluminum substrate and cured in an oven to achieve a dry film thickness of at least 30 micrometers. Alternatively, a three-coat system may be used, consisting of a primer, a color coat, and a clear coat, with a dry film thickness of at least 40 micrometers.
