Environmentally friendly systems are therefore becoming increasingly important worldwide. As a result, BYK has launched two new wetting and dispersing additives for aqueous systems this year, namely DISPERBYK- 2080 and DISPERBYK-2081. Both additives offer optimal dispersion and stabilisation of pigments and fillers, without impacting the water, corrosion and stain resistance of the coating system. In this way, modern, solvent- free additives emphasise the current trend for environmentally friendly problem solving while also offering extraordinary performance, especially in wood, furniture and protective coatings.
Optimal rheology allows for perfect processing and application. The two new associative thickeners for the water-based additive range, OPTIFLO-T 1010 and OPTIFLO-H 7625 VF, provide the coating system with a bespoke rheology profile in the respective coating application range. While OPTIFLO-H 7625 VF dramatically increases viscosity in the low shear range and generates highly pseudoplastic flow behaviour, OPTIFLO-T 1010 offers a near-Newtonian rheology profile with increased viscosity in the high shear range, and also delivers on the environmentally-friendly front. Both liquid products are free of VOC, APEO and tin.
