Descrição:
RHEOBYK®-D 410 by BYK is a liquid rheology additive for medium-polarity solvent-borne and solvent-free systems to generate highly thixotropic flow behavior. It enables PVC plastisols to be manufactured and processed more quickly and improves the anti-settling behavior and antisagging properties. It minimizes flooding and floating in pigmented plastisols and improves the control of the coating profile in the gelling oven. Foam stability is increased in mechanically frothed PVC foams. The recommended level is 0.1-0.5 phr additive (as supplied) based on the PVC resin to prevent settling & floating and 0.3-1 phr additive (as supplied) based on the PVC resin to prevent sagging. In exceptional cases doses of up to 3 phr are possible. RHEOBYK®-D 410 is highly suited for preventing sedimentation in filled, reactive casting resin systems such as epoxy, polyurethane and acrylate resins, and also in some polyester resins. Using the additive makes it possible to increase the anti-sagging properties without impairing leveling. Generally, it only increases the viscosity at low shear rates and therefore does not influence the application properties at high shear rates.
