Two Versatile New Additives DISPERBYK®-2020 is a new high-molecular pigment wetting and dispersing additive based on controlled polymerization technology.

CRP offers the unique chance to tailor additives to market requirements. DISPERBYK-2020 has been developed for use in solvent-borne architectural, industrial, wood and furniture coatings and in the manufacturing of pigment concentrates.

With the new BYK®-430, BYK-Chemie provides a highly effective, easy-to-handle rheology additive especially suited for solvent-borne epoxy primers and high-build coatings with dry film thickness from 300 µm to 1000 µm. BYK-430, supplied as a liquid, needs only one step for incorporation. Even at low temperatures and low shear incorporation, it shows a strong rheology effect. An excellent improvement of sag control is guaranteed due to fast viscosity recovery after shear thinning during application. Post addition is possible for final viscosity adjustment.
