Additol BDK 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 BDK undergoes a photochemical reaction that generates radicals. These radicals will initiate polymerisation through the unsaturated groups present in the system. PERFORMANCE HIGHLIGHTS Additol BDK is characterised by: Good solubility UV curable formulated products containing it are characterised by: Good 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: Wood fillers and sealers Basecoats for metals Overprint varnishes General coating applicatoins where low yellowing is not critical Inks and pigmented coatings(in combination with other photoinitiators) 2,2-Dimethoxy-1,2-diphenylethan-1-one. Exhibits good solubility, balanced surface and through cure, and good shelf stability. Used in wood fillers and sealers, basecoats for metals, and overprint varnishes.
