Additol HDMAP is a general purpose 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 HDMAP undergoes a photochemical reaction that generates radicals. These radicals will initiate polymerisation through the unsaturated groups present in the system. PERFORMANCE HIGHLIGHTS Additol HDMAP is characterised by: Low viscosity Good solvency UV curable formulated products containing it are characterised by: Balanced surface and through cure Good shelf stability 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 1-5% by weight based on the reactive components of the formulation. Applications include: Clearcoats for metal and plastics Wood top-coats Overprint varnishes Paper upgrading Inks and pigmented coatings (in combination with other photoinitiators) 2-Hydroxy-2-methyl-1-phenyl propanone. Exhibits good solvency, balanced surface and through cure and good shelf stability. Used in clearcoats for metal and plastics, wood top-coats and overprint varnishes.
