Color coating composition for LED lamp diffuser and color-coated glass article using the same
Disclosed herein are a color coating composition for an LED lamp diffuser and a color-coated glass article using the same. The color coating composition is capable of increasing durability and a life of an LED lamp, satisfactorily maintaining an external appearance and a lighting quality thereof for a long time, and realizing various colors, by manufacturing a glass-made diffuser as a means for diffusing light of the LED lamp in a manner of coating the diffuser on various sheets of transparent or translucent glass such as tubes and bulbs so that the diffuser is not deformed and discolored due to light and heat, and has high strength and translucency.
SUSTAINABLE POLYBUTYLENE TEREPHTHALATE COMPOSITIONS WITH IMPROVED COLOR CAPABILITY
Thermoplastic compositions include from about 15 wt % to about 98 wt % of a polybutylene terephthalate (PBT) component, from about 2 wt % to about 10 wt % of at least one brightening agent and from 0 wt % to about 83 wt % of at least one additional component. The PBT component includes PBT derived from post-consumer or post-industrial recycled (PCR) polyethylene terephthalate (PET). In particular, the PBT may be derived from the PCR PET by first depolymerizing the PCR PET to form a high purity bis(2-hydroxyethyl) terephthalate (BHET) monomer (e.g., greater than 95% purity), and then polymerizing the high purity BHET monomer with butane diol (BDO) to form the PBT.
