DISPERBYK-2180 is suitable for a wide range of applications, including architectural coatings, industrial coatings, and automotive OEM coatings. Besides these, the additive is also deployed in marine coating and corrosion protection. The underlying polycarboxylate-ether structure thus extends the available spectrum of potential solutions for the dispersion of inorganic pigments and fillers.
With DISPERBYK-2180, BYK
has introduced a new wetting and dispersing additive for inorganic pigments and fillers in water-based systems. The polycarboxylate-ether-based additive is designed for applications requiring a high degree of stability across a wide pH range.
The polycarboxylate-ether-based structure of DISPERBYK-2180 opens up further formulation opportunities and meets the growing importance of ecological demands. Due to its tolerance of extreme pH values, the additive is ideal for use in VOC-free architectural coatings - such as (dispersion) silicate paints. Its molecular structure with a high concentration of ionic adhesive groups allows DISPERBYK-2180 to be particularly effective in deflocculating and stabilising of all kinds of inorganic particles such as titanium dioxide, transparent iron oxides and fillers.
The additive also ensures a distinct reduction in mill base viscosity, thereby permitting high pigment dosages and, at the same time, good processability. Fine particle sizes and a uniform distribution of particles are achieved resulting in an extremely positive effect on color and transparency.
