Tego Dispers 685 For Rad-Cure Inks
Tego Coating Additives and Specialty Resins has introduced Tego Dispers 685, a new wetting and dispersing additive designed for preparing pigment concentrates for radiation curable industrial coatings and printing inks.
Tego Dispers 685, a high molecular weight polymer, is a free-flowing clear liquid, supplied 100% active. It is easy to dissolve in conventional monomers, monomer/oligomer resin blends or in a variety of common solvents. It is suitable for pigment grinding on three roll mills or media mills and is added to the grind at levels of 15-30 percent as supplied, calculated on total pigment weight.
Dispers 685 is especially suitable for some organic pigments, such as yellow, red and blue and produces outstanding development of color strength, improved rheology, lower yield point and strong reduction of mill base viscosity allowing for high pigment loading.
