K2942 THICKENER #2: White Powder- An excellent thickener for High Density printing. Add up to 1% by weight to thicken plastisol ink, results are immediate. By increasing viscosity, the ink film will sit on substrate surface, improving opacity. Excessive amounts of Thickener 2 will cause build-up on back of screen and accelerate the aging of the ink viscosity. High speed, high shear mixing will disperse powder without lumping. Be cautious to not overheat the ink.
