Silk screen HD tempered film provides users with a high-definition visual experience while protecting the screen of electronic devices. The application of anti-fingerprint coating technology further improves its convenience and aesthetics, effectively solves the problem of blurry screen caused by fingerprint contamination, and achieves long-term anti-fouling.
Anti-fingerprint coatings usually use materials such as fluorine-containing polymers. These materials have extremely low surface energy, which can make it difficult for substances such as grease in fingerprints to adhere to the surface of the film. The fluorine atoms in the molecular structure of fluorine-containing polymers have high electronegativity and large carbon-fluorine bond energy, making the coating surface smooth and stable. For example, polytetrafluoroethylene is a common fluorine-containing material with extremely low surface energy, which can effectively prevent the adhesion of fingerprint stains and provide a basic guarantee for long-term anti-fouling.
Anti-fingerprint coatings have a special microstructure. Through advanced preparation technology, the surface of the coating is constructed with a nano-scale rough structure or porous structure. This microstructure increases the contact angle between the coating and fingerprint stains, making the stains form water droplets on the surface, which are difficult to spread and adhere. When a finger touches the surface of silk screen hd tempered film, the stain can only contact the top of the microstructure instead of adhering to the surface of the film over a large area, thereby reducing the residual fingerprints and making it easier to remove the stains during daily wiping, thus achieving long-term antifouling.
During the coating preparation process, the surface of silk screen hd tempered film is modified so that the coating and the film surface are tightly bonded by chemical bonding. For example, plasma treatment and other technologies are used to introduce active groups on the surface of silk screen hd tempered film, which then react chemically with the corresponding groups in the anti-fingerprint coating material to form a strong chemical bond. This chemical bonding not only improves the adhesion of the coating, but also prevents the coating from falling off during long-term use, ensuring the integrity and long-term effectiveness of the anti-fingerprint coating, thereby achieving long-term antifouling.
Some anti-fingerprint coatings also have a certain self-cleaning function, which also helps to achieve long-term antifouling. Some coating materials can produce photocatalytic reactions under light conditions, decomposing organic stains attached to the surface into harmless substances such as carbon dioxide and water. For example, anti-fingerprint coatings containing titanium dioxide can produce highly oxidizing free radicals under ultraviolet irradiation. These free radicals can destroy the chemical bonds of organic substances such as oils in fingerprints, decompose them and make them easily washed away by water, thereby keeping the surface of silk screen hd tempered film clean.
Appropriate coating thickness and uniformity are essential to achieve long-term antifouling. Too thin a coating may not provide adequate protection and antifouling performance, while too thick a coating may affect the transparency and touch of silk screen hd tempered film. Through precise coating processes such as spin coating, spray coating, etc., combined with advanced testing equipment, the thickness and uniformity of the coating can be precisely controlled. Uniform coating can ensure consistent anti-fingerprint and anti-fouling properties across the entire surface of silk screen hd tempered film, avoid easy adhesion of stains due to local coating defects, and achieve long-term antifouling.
The anti-fingerprint coating technology of silk screen HD tempered film achieves long-term anti-fouling through the synergy of multiple means such as selecting suitable materials, designing special microstructures, chemical bonding and surface modification, utilizing self-cleaning functions, and precisely controlling coating thickness and uniformity. This technology provides users with a more convenient and beautiful use experience, effectively prolongs the cleaning cycle of silk screen HD tempered film, and improves the overall performance of the product.
