光触发剂 Photoinitiator 丙烯酸/丙烯酸盐树脂 Acrylic/Acrylate Resins 乙烯基 Vinyl 涂层 >> UV / 辐射线固化 Coatings >> UV / Radiation Curing 木器 &家具涂层 Wood & Furniture Coatings IRGACURE 1800 is a solid photoinitiator for radical polymerisation of unsaturated resins after UV light exposure. It is especially suited for white pigmented formulations and for curing thick sections. IRGACURE 1800 may be used, after adequate testing, in UV curable formulations for clear and for pigmented coatings on wood, metal, plastic, paper and optical fibers as well as for printing inks and prepregs. Suitable UV curable formulations may be based on acrylate resins, UPES/styrene or UPES/acrylate monomer systems. For patent reasons, however, the use of this product is not allowed in dental applications. IRGACURE 1800 exhibits outstanding curing performance in highly opaque white furniture coatings or screen inks containing rutile titanium dioxide and affords minimum yellowing after exposure to sufficient amounts of UV radiation. Additionally the outstanding absorption properties of IRGACURE 1800 allow curing of thick sections. Due to its enhanced photosensitivity at longer wavelengths, IRGACURE 1800 can easily be used in combinations with UV absorbers, e.g. TINUVIN ® 400. It is therefore ideally suited for use in weather-resistant UV curable coatings. The amount of IRGACURE 1800 required for optimum performance should be determined in trials covering a concentration range.
