中固化学® BP M250 is a difunctional, polymeric benzophenone-based photoinitiator engineered for UV-curable systems where low migration and low volatility are critical. Its high molecular weight structure provides enhanced performance stability and reduced tendency to migrate from the cured film, making it a superior and reliable alternative to conventional benzophenone. It is particularly effective when used in combination with 胺促进剂/胺增效剂s and is well-suited for both clear and pigmented coatings.
