Wetting and dispersing additives for aqueous coating systems always possess a certain hydrophilic character. Essentially, they are needed to wet, disperse and stabilize pigments and fillers. However, the hydrophilic structure of the additives also continues to have an impact in the cured coating film. This may cause key film properties such as water, corrosion and stain resistance to be impaired.
DISPERBYK-2080 and DISPERBYK-2081 are new additives that are particularly suited to aqueous anti-corrosive primers, direct to metal systems, and aqueous wood and furniture coatings. They offer significant viscosity reduction and a good deflocculation, especially of inorganic pigments, fillers and anti-corrosive pigments, without impairing the coatings´ resistance.
These two highly interesting additives prove BYK´s outstanding technological expertise. They do not only make possible what seems to be so difficult: a combination of good viscosity reduction and deflocculation of pigments on one hand and the least negative influence on water, stain, and corrosion resistance on the other. Additionally, to support the determination of the anti-corrosion properties of coatings, a cutting-edge testing technology was applied, the Electrochemical Impedance Spectroscopy (EIS), providing evidence that BYK is handling measurements according to the latest standards. For further information on the use of EIS at BYK please contact your local BYK partner.

Pigment concentrates are commonly used to color architectural coatings, both in the professional and the DIY field. It is true that aqueous systems dominate the market; however, solvent-borne alkyd coatings and high-solids, for example, are still widely used. DISPERBYK-2060, DISPERBYK-2061 and DISPERBYK-2062 comply with BYK's claim to provide an environmentally friendly, highly effective and customer-oriented solution. They offer a broad compatibility in aqueous and solvent-borne systems, cover the entire spectrum of inorganic and organic pigments, as well as carbon blacks. DISPERBYK-2060, DISPERBYK-2061 und DISPERBYK-2062 are VOC and APEO-free and have no influence on the coating viscosity or the coating drying respectively.
