>Who Is The Earliest Use PVDF Coating In The World?
In 1965, the Pennwalt Chemical Company of the United States first used PVDF coatings to meet the coating of aluminum materials inside and outside high-end buildings.
Definitin of PVDF coatings
PVDF coating is PVDF resin mainly refers to vinylidene fluoride homopolymer or vinylidene fluoride and other small amounts of fluorinated vinyl monomer copolymer coating. The chemical structure of the fluoric acid base is bound by fluorine/carbonization bonds.
Why PVDF coating is different from those of general coatings？
The stability and firmness of this chemical structure make the physical properties of PVDF coatings different from those of general coatings. In addition to the wear resistance in terms of mechanical properties, the impact resistance has excellent performance, especially in harsh climates and environments showing long-term fading resistance and UV resistance. After the film is baked at high temperature, the molecular structure of the coating is tight, and it has superior weather resistance.
The Type of PVDF coatings
PVDF coatings can be divided into traditional PVDF coatings and nano-PVDF coatings according to the film formation structure of the surface.
The advantage of PVDF coating
The wide choice of colors, beautiful and solemn appearance, and durability added luster to many magnificent curtain wall buildings around the world. The coating manufacturer's guarantee of the service life of the coating began to be 10 years, 15 years to guarantee more than 20 years. American research institutions have tested and compared PVDF coatings and super coatings and general coatings, and the samples of the coatings are exposed to hot sunlight in Florida, the United States, and exposed to the harsh environment of wet and salty air for 12 years, which actually proves that the stability and durability of PVDF coatings are 30 and 80 percentage points higher than the other two coatings. PVDF coatings guarantee use in a variety of harsh environments. Especially suitable for indoor and outdoor decoration in public places, commercial chain, exhibition advertising and other decoration and display.
OUR ADVANTAGES
Smoothness
There is no residual stress on the surface and no deformation after shearing
Weather resistance
The paint pattern made by roller coating and high temperature baking has high gloss, good color stability and little color difference change
Decorative
There is a fresh natural beauty, the pattern is casual and do, give customers a wide range of personality choices, can enrich the culture of the product, give people more beautiful enjoyment.
Environmental Protection
Resistant to salt, alkali and acid rain corrosion, will not corrode or produce toxic bacteria, does not release any toxic gases.
Mechanical
ACP after composite with plastic and adhesive. With the flexural and flexural strength required by the decorative plate, in the four seasons climate, the change of wind pressure, temperature, humidity and other factors will not cause bending, deformation,expansion and so on.
