Application of Spray Coating in Aluminum Surface Treatment
Release time:
Dec 17,2024
Fluorocarbon spray coating is a coating made from polyvinylidene fluoride resin nCH2CF2 baked (CH2CF2) n (PVDF) as the base material or mixed with metal aluminum powder as the pigment. In the chemical structure of fluorocarbon based materials, the fluorine/carbide bond, which has short bond properties, is considered the most stable and firm bond with hydrogen ions. The stability and firmness of the chemical structure make the physical properties of fluorocarbon coatings different from general coatings. In addition to excellent wear resistance and impact resistance in mechanical properties, it also exhibits long-lasting anti fading and anti UV properties, especially in harsh climates and environments.
In 1965, Pennwalt Chemical Company in the United States first synthesized a building topcoat, also known as metallic paint, using polyvinylidene fluoride as the base material and metal particle aluminum powder, and used Kynar500 as the trademark. As a result, manufacturers around the world have started using Kynar500 to produce their own fluorocarbon coating topcoats to meet the coating needs of high-end indoor and outdoor aluminum materials in buildings. The wide range of color choices, beautiful and dignified appearance, and durability have added luster to many magnificent curtain wall buildings around the world. The coating manufacturer's guarantee for the service life of the coating starts at 10 years, develops from 15 years to a guarantee of 20 years.
A research institution in the United States has conducted tests and comparisons on fluorocarbon coatings, super coatings, and general coatings. Samples coated with fluorocarbon coatings were exposed to scorching sunlight in Florida, USA, as well as harsh environments with humid and salty air for 12 years. It has been proven that the stability and durability of fluorocarbon coatings are 30 and 80 percentage points higher than the other two coatings, ensuring their use in various harsh environments.
