Additol DMMTA is a radical photoinitiator that can be used alone or in cmbination with other photoinitiators. It is used in formulations containing unsaturated materials such as acrylates, methacrylates, vinyls and unsaturated polyesters. With exposure to UV light, Additol CPK undergoes a photochemical reaction that generates radicals. These radicals will initiate polymerisation through the unsaturated groups present in the system. Additol DMMTA is particularly suited for the curing of pigmented coatings and inks. The reactivity of Additol DMMTA can be significantly improved when combined with Additol ITX. PERFORMANCE HIGHLIGHTS Additol DMMTA is characterised by: Low volatility Good solubility UV curable formulated products containing it are characterised by: Good surface Good through cure in pigmented systems. The final properties of UV cured products also depend on the selection of other components such as oligomers, reactive diluents and additives. SUGGESTED APPLICATIONS: It is typically used at levels of 2-4% by weight based on the reactive components of the formulation. Applications include: Flexographic inks Offset inks Screen inks Pigmented coatings 2-methyl-1-[4-(methylthio)phenyl]-2-morpholino-propan-1-one. Exhibits good solubility, good surface and through cure and low volatility. Used in flexographic, offset and screen inks, and pigmented coatings
