Starting with basic polymer synthesis such as UV resin, Bestroom Co., Ltd. has been researching and developing eco-friendly, safe, and durable UV adhesive, OCR and PDLC mixtures for construction and display.
Since its founding in 2001, Bestroom has been producing laminating resin used in safety laminated glass and polymer dispersed liquid crystal films using privacy films and units of IoT. The company also produces display industry and laminating adhesives used in LCD and electronic and telecommunication. Bestroom’s new material technology has been accumulated through R&D based on organic and inorganic synthesis materials for 16 years.
Smart VU Film
Smart VU Film, known as PDLC film, is an electronic component that can actively adjust the penetration rate of solar light. It is a new material that adjusts the penetration of visible rays according to the presence or absence of electricity. Smart film enables a film to be transparent or opaque in both normal and reverse mode depending on on/offoperation using electrical signals. PDLC mixture is laminated between two transparent conductive coated PET or glass layers. PDLC mixture consists of droplets of liquid crystal which contains bipolar alignment.
This mixture is dispersed in a matrix prepolymer binder. In the absence of an electronic field, the droplet director is randomly aligned and the refractive index of the droplet is mismatched with that of the prepolymer, which causes the light to scatter. In this state, the film of the PDLC can be switched to an index-matched and transparent state when the electric field that aligns the droplet director parallel, is applied.
UVLAM is the only product in the country that has obtained American safety joint standard ANSI Z97.1-2009 and CPSC 16 CFR 1201. ANSI certification is valid only after passing the tests of Architectural Testing Inc., an official U.S. government agency located in the United States. UVLAM is certified to ANSI Z97.1-2009 (Class A) and CPSC 16 CER 1201 (Class II).
