Ink Rheology Modifier (Thixotrope)
Organoclay or fumed silica-based thixotropic agent designed for offset and screen printing inks. Controls ink flow and body without causing pigment settling, providing the short-flow behavior required for sharp dot reproduction. Recommended addition level is 1–3% with high-shear dispersion for full thixotrope activation.
