| The strongest absorption band of YL-PI 1173 is around 260nm, which is useful for clear coating. So YL-PI 1173 is a highly efficient photoinitiator for clear coating. Being a liquid of low volatility, it is easy to add otherwise complete formulation. Owing to YL-PI 1173 features excellent photo-resistance, it is particularly suitable for non-yellowing UV curing system. YL-PI 1173 features high reactivity, because it owns high quantum absorption and can form reactive free radical. The choice of suitable photoinitiator for a specific formulation can only be determined by experimental trials, optimum levels will be influenced by such factors as the thickness of the coating, degree of pigmentation, type of media and so no. Suggested application levels are 2~6%w/w, expressed as a percentage of the total formulation. Application fields include UV curing coating for wood, paper, metal and plastics. |
