Q1: What is the primary function of ARADUR HY 905 CI in epoxy coating systems?
A: ARADUR HY 905 CI is a latent, cationic photoinitiator specifically designed to enable UV-curable epoxy coatings. It remains inactive under ambient conditions but rapidly generates strong Brønsted acids upon exposure to UV light, initiating rapid and efficient ring-opening polymerization of epoxy resins.
Q2: Is ARADUR HY 905 CI compatible with common epoxy resins used in industrial coatings?
A: Yes — it demonstrates broad compatibility with standard bisphenol-A and bisphenol-F based liquid and solid epoxy resins, as well as multifunctional epoxy novolacs. Compatibility should be verified experimentally within the final formulation due to potential interactions with additives or fillers.
Q3: How does HY 905 CI contribute to performance in high-gloss, low-VOC coating applications?
A: As a non-volatile, halogen-free photoinitiator, HY 905 CI supports the development of high-solids and solvent-free epoxy coatings. Its efficient cure profile helps achieve excellent surface hardness, chemical resistance, and optical clarity—key requirements for premium gloss finishes without compromising environmental compliance.
Q4: What handling precautions are recommended for safe use?
A: Standard industrial hygiene practices apply: avoid inhalation of dust, direct skin contact, and eye exposure. Use appropriate PPE including nitrile gloves and safety goggles. Store in a cool, dry place away from UV sources and strong oxidizing agents. Refer to the Safety Data Sheet (SDS) for detailed toxicological and first-aid information.
