It is especially suited for white pigmented formulations, curing of thick sections and for resins for glass fibre reinforced materials. IRGACURE 1700 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. For patent reasons, however, the use of this product is not allowed in dental applications. Suitable UV curable formulations may be based on acrylate resins, UPES/styrene or UPES/acrylate monomer systems. As a liquid photoinitiator, IRGACURE 1700 is especially easy to incorporate into formulations. IRGACURE 1700 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 1700 allow curing of thick sections. Due to its enhanced photosensitivity at longer wavelengths, IRGACURE 1700 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 1700 required for optimum performance should be determined in trials covering a concentration range.
