DisperBYK-2155 wetting and dispersing additive for solvent-free and solventborne systems is 100% high solids and VOC-free. Environmental concerns have lead to modified coatings formulations, and in the recent past there has been growing demand for high-solids systems. This technology calls for additives with high solids content. Often, these additives suffer from poor flowability, in particular if they have a higher molecular weight. Bringing the opposites in line, BYK developed a high molecular, 100% solids additive that provides outstanding deflocculation and stabilization, but avoids the usual drawbacks. DisperBYK-2155 is entirely flowable, storage stable and covers a wide compatibility range. DisperBYK-2915 is VOC-free and suitable for all applications where VOCs are a concern. Benefits include flowability and high molecular weight at the same time, good millbase viscosity reduction, no yellowing in baking systems, no impact on drying time of 2-pack systems and wide compatibility.
