What Is The Difference of PE Paint and PVDF Paint for Coated Aluminum?

The paint for Color coated aluminum coil can be classified into two types- PE paint (Polyester paint) and PVDF paint (Fluorocarbon paint). Most people know PVDF paint is much expensive than PE paint. Yet do you know why it is expensive? Do you understand the difference of PE paint and PVDF paint of color coated aluminum coil? You will learn more by reading my words below.

1. PE paint of Color Coated Aluminum coil

The PE coating formed on the surface of the aluminum sheet by multiple baking has protective and decorative properties for the aluminum sheet. PE coating is a kind of anti-UV UV coating. The UV absorber can be divided into sub-gloss and high-gloss series according to the glossy degree. PE paint not only can give rich colors for color coated aluminum products which is with good gloss and smoothness, as well as superior texture and hand-feeling, but also can increase the sense of hierarchy and three-dimensional. PE paint can protect the atmosphere exposed object from the ultraviolet radiation, wind, rain, frost snow and frozen attack. Due to the temperature, freeze-thaw cycle, corrosive gases and microbial effects, the PE coating can play a protective role for the object. PE paint is especially suitable for interior decoration and billboards.

2. PVDF paint of Color Coated Aluminum coil

Fluorocarbon coating is PVDF resin paint. The chemical structure of the fluoric acid base is bounded by fluorine- carbon bonding. The chemical structure stability makes the PVDF coating’s physical property different from the general coating. In addition to excellent performance for the mechanical properties of the wear resistance, impact resistance, the PVDF coating shows a long anti-fading, anti-ultraviolet performance especially in the harsh environment. After high temperature baking film, the molecular structure in the coating is close which has superior weather resistance property.

The PVDF coating is mainly used for painting and decorating the building indoor and outdoor aluminum. Widely colors for choosing, makes many magnificent building’s curtain wall more solemn, durable and gorgeous. The use life for PVDF paint is more than 20 years. USA research institutes tested and compared the PVDF coating, super coating and common coating by placing the three samples in the Florida, United States with hot sun exposure, as well as in humid salty air with 12 years exposure. This test conclude that the stability and durability of PVDF coating is 30 percentage than super coating and 80 percentage than common coating. The PVDF coating is ensured that the PVDF color coated aluminum coil can be used in variety of harsh environments.
