Why choose ASA film used in color steel tile?
First, let us know what is ASA?
ASA (Acrylonitile,Styrene,Acrylate) is a kind of Polymer, and it belongs to a impact modified resin. Has excellent weather resistance, so it is the first choice for outdoor building materials.
ASA has the advantages of lasting color, stable performance, saving cost and so on, so that the market demand of ASA is increasing day by day.
And what is the character of color steel tile?
Color steel tile is made of color coated steel plate by rolling and cold bending.
The color coated steel plate is based on galvanized, aluminized and tinned steel plate or cold-rolled steel plate, and the color organic coating or film is used as the decorative protective layer.
The service life of color coated steel plate is largely restricted by the protective layer
We can see steel tile colors are various. But in the spraying process of primary coating (primer) and fine coating (front and back coating), color steel coated steel plate should face the problems of solvent volatilization and leakage, and the increasingly severe environmental protection problems, the subsequent investment in process cost will continue to increase.
How to solve this problem? Engineers found ASA material and ASA film. ASA film is made of super weather resistant thermoplastic ASA resin and weather resistant color powder by blending and extruding the film. The film has high strength, good toughness and long-lasting color. It is especially suitable for outdoor harsh wind, sun, rain and corrosion environment.
ASA film has many colors for choice and its application is very simple. But its ecnomic efficiency is much higher than spraying on steel tiles.
