Group No.4 Oil & water repellent
① Oil-and-water-repellent coating
■What is an oil-and-water-repellent coating?
An oil-and-water-repellent coating is a coating film that uses our original technology and has high repellency. Droplets run off the surface of the coating quickly. It does not allow droplets to rest on the surface.
■Main features
The oil-water-repellent coating has an excellent property to repel droplets, prevents adhesion of water and oil, and maintains water and oil repellency at high temperatures.
② Super-water-repellent coating
■What is a super-water-repellent coating?
A super-water-repellent coating uses special raw material and has a microscopic structure on its surface. A contact angle between the coating and a droplet is so large (approximately 150°) that droplets are repelled, do not stay, and run off the surface.
■Main features
The coating gives an excellent property to repel droplets to the surface of a base material.
Since the coating can be created at low temperatures, it is applicable to various kinds of base materials.
③ Ultra-hydrophobic coating
■What is an ultra-hydrophobic coating?
An ultra-hydrophobic coating has a special surface effect to increase a contact angle. Owing to a large angle of contact, droplets take a spherical shape and run off smoothly.
■Main features
The repelled droplets maintain the spherical shape while they are running off and do not run on the surface.
④ Hydrophilic coating film
■What is a hydrophilic coating film?
A hydrophilic coating film has an affinity for water. An angle of contact between a waterdrop and the film is very small.
■Main features
Since the contact angle between the film and waterdrops is extremely small, waterdrops run on the surfaces of a part coated with the film.
⑤ Transparent water repellent film
■What is TRANSPARENT WATER REPELLENT FILM?
Transparent water repellent film is an antifouling film that reduces soil left on the surface of a base material, such as fingerprints. Therefore, the soil is easily wiped off.
■Main features
Transparent water repellent film is a highly transparent film that gives water repellency and oil repellency to the surface of a base material. Since this film cures at normal temperatures, it can be applied to material with low heat resistance.
Applicable materials: Acrylic resin, resins used for personal computers,
glass, and other materials
