DISPERBYK-2055 – Perfect Alternative for a Multitude of Cost-sensitive Formulations
For years now, many paint manufacturers have tried to minimize the number
of raw materials used in their products. This also applies particularly to additives.
DISPERBYK-2055 is a high molecular-weight wetting and dispersing additive
that covers a very broad application spectrum. It can be used in solvent-borne,
solvent-free, and aqueous systems. DISPERBYK-2055 enables the production
of high-quality pigment concentrates that can be used to cover almost the
entire polarity range of let-down binders – from long oil alkyds through to
aqueous binder systems. DISPERBYK-2055 is also extremely well suited for
co-grinds, i.e. where pigment blends are being used during the grinding
phase. As DISPERBYK-2055 deflocculates and stabilizes both, inorganic and
organic pigments, and also provides outstanding results with fillers and matting
agents, such co-grinds now only require one wetting and dispersing additive.
There is no doubt that the cost factor plays an increasingly greater role.
The smart selection of some key raw materials and a highly efficient production
process have led to the development of a product that is not only of high
quality, but also exhibits an outstanding price-performance ratio.
