Details:

Tianjin Radchem Technology Co., Ltd. (www.radchemtech.com) was founded in 2018 by a team with more than ten years of R&D, production and marketing experience in the industries of photoinitiators, coatings & plastic functional materials and drug synthesis. It integrates research, production and marketing, and committed to developing characteristic products and applications. At present, the company has a school-enterprise cooperative laboratory, two pilot laboratories, and two production cooperation factories, mainly responsible for the scale-up and commercial production of technical projects, and the annual capacity of special photoinitiators, characteristic functional materials and pharmaceutical intermediates up to 1,000 tons.
OX-1 is a highly efficient photoinitiator, it is particularly suitable for applications requiring high photosensitivity in combination with low yellowing. It has an absorption band in the region of 300-400 nm. The peak wavelength is 325 nm and the absorption edge reaches 400 nm, which is expected to be sensitive to the light at or below i-line (365 nm). Based on the solubility measurements, HRCure-OX01 is highly soluble in the solvents such as propylene glycol monomethyl ether acetate (PGMEA) and cyclohexanone, which typically are used in color filter resists. HRCure-OX01 exhibits an outstanding curing performance in highly pigmented resist formulations, mainly applied for Color-filter resists and black matrix resists for display applications; in addition, it can also be applied in photo-sensitive polymide formulations, in spacer materials for LCD, in microlens materials, in overcoat layers and in dielectric and insulating layers. Recommended concentration is 2.0-5.0% in Color Filter Resist or 1.5-3.0% in Photosensitive Polyimides. High light sensitivity, low yellowing, LED365nm. It is used in the production of high-end LCD color glue and low light curing system.
