Firstcure HMPP 2-Hydroxy-2-methyl-1-phenyl-1-propane-one 7473-98-5 Albemarle Photoinitiator Acrylic/Acrylate Resins Coatings >> UV / Radiation Curing Inks >> UV / Radiation-curable INKS FIRSTCURE HMPP photoinitiator is a clear, high-boiling-point liquid compatible with acrylate monomers and oligomers used in UV-curable systems. It is an effective photoinitiator for UV-curable acrylate-based coatings, adhesives and inks that offer non-yellowing properties, good shelf stability and a fast cure rate. It is available in liquid form for ease of formulation. It is particularly useful for photocuring clear acrylate-based formulations where non-yellowing is important. It is also recommended for pigmented inks where shelf stability and color stability are essential. FIRSTCURE HMPP photoinitiator can be used at concentrations of 0.1% to 4.0% by weight in UV-cured systems. Photoinitiator, high-boiling-point liquid compatible with acrylate monomers and oligomers. It is used in UV-curable acrylate-based coatings, adhesives and inks. Offers non-yellowing properties, good shelf stability and a fast cure rate.
