Coatings where High clarity polyme and Polar group are introduced.
Excellent high adhesiveness, moisture resistance, etc.
Applicable to appearances including TV stand/monitor/smartphone.
Coating specifications differ by the applied materials.
(Able to recommend urethane, epoxy, lacquer products)

Mobile Devices

Coatings used in smartphones, tablets, wearables, other accessories, etc.
Products are classified by material type and the coating method.
Smartphone coatings are classified as coatings for interior/exterior/accessories.
Exterior coatings can express a variety of colors/textures/functions.
For wearable coatings, wider materials including silicone are used.

Coating Types

01 Urethane
As coatings formed by a urethane bond in the reaction to form a paint film, adhesiveness, chemical resistance, abrasion resistance, and weatherability are outstanding.
Applications: Heavy equipment, railway vehicles, etc.
02 Epoxy
As volatile-solvent, fast-drying coatings, it forms dry film in a short period of time and is characterized as a high gloss.
Applications: Universal use and repair of wood, steel, etc.
03 Lacquer
As air-drying 2-components enamel whose major ingredient is epoxy resin, it has superior adhesiveness, chemical resistance, water resistance, and electrical properties.
Applications: Transformers, ultra-high pressure breakers, etc.
