They are used in compounding mixtures to control viscosity and thicken the formulation. For compounds that undergo high shear stress or deformation, rheology additives are critical to maintaining the integrity and composition of these mixtures. Applications Rheology modifiers offer improved viscosity and high efficiency for adhesives, sealants, industrial coatings and plastisols. During the application and curing process, they ensure sag resistance and high efficiency. They also prevent pigment sedimentation during transportation and storage. Because these thickeners can demonstrate thixotropic behavior, they are ideal for use in mechanical, PVC, urethane and modified silicone solutions. These thixotropic properties are achieved through chemical branching, water absorption or mechanical thixotropy. Additive Suppliers At H.M. Royal, we’re more than just material people.
