Excalibur’s TH200 Powdered Thickener is a powder that when added to any Excalibur plastisol ink will immediately increase the viscosity.  Add in increments of 0.5-5% by weight until the ink has reached the desired viscosity.  The advantages of TH200 over liquid thickeners is that inks thickened with TH200 will retain the viscosity during printing.  TH200 should be mixed into the ink using a drill with a mixing attachment or a mixer so that the powder is completely dispersed into the ink.
