TRIONOL

Trionol™ 1739 A is a Lawter™ specialty alkyd. Trionol 1739 A is a medium oil-length soya oil alkyd that forms hard, tough ink films with low odor. It has better compatibility with hard resins than Terlon 7 A and is recommended for low odor inks used on napkins, food cartons, etc. Trionol 1739 A is an excellent replacement for linseed alkyds in heatset inks whenever it is cost effective to do so. Trionol 1739 A is recommended for three-piece flat metal decorating lithography. It has good baking properties on metal with good color retention at oven temperatures up to 370°F. Faster baking can be achieved by adding up to 10% melamine to finished inks based in Trionol 1739 A. Trionol 1739 A avoids the gloss ghosting or yellow ghosting that sometimes occurs in sheetfed inks.

When printed on coated paper, a Trionol™ 3 A based ink partially penetrates and oxidizes, providing a tough anchor. The remainder of the Trionol 3 A remains on the surface as a film-forming coating that rapidly hardens to a tough, rub-resistant print. Trionol 3 A, with exceptionally good pigment wetting properties, can improve gloss, setting speed and rub resistance, in contrast with many pigment-wetting vehicles that detract from gloss and setting speed. The use of driers, resinates or reactive metals on pigment surfaces will gel Trionol 3 A. The increase in viscosity caused by the use of metallic driers can be modified by the addition of one-fourth the drier weight of an anti-skinning agent. The viscosity of Trionol 3 A is stable in finished inks. Trionol 3 A can replace drying oils in quickset and heatset vehicles to improve compatibility, solvent tolerance, pigment wetting, and rub resistance without sacrificing setting speed.
