Products in Printing & Inks: Plastisol Sealant

AMI Chemical Corporation COAG-40 is an additive that controls sag and pigment settling in PVC plastisol coatings and sealants with a Thixotropic effect by creating a more shear-thinning rheological behavior. This means that the flow and ease of application are not affected. COAG-40 can simply be stirred into the formulation. The gel structure is not broken down by heat, giving sag control at all temperatures, even during the gelation process. Stable viscosity is reached in minutes, not hours or days as can be the case with other products such as precipitated and fumed silicas.
