BYK-9076

Solvent-free wetting and dispersing additive for solvent-borne and solvent-free coatings. Particularly recommended for carbon black pigments. Prevents separation and improves the fibre wetting in SMC/BMC formulations. BYK-9076 deflocculates pigments by means of steric stabilisation. It also generates a uniform electrical charge in the pigment particles. The resulting repulsion effect and the steric stabilisation prevent any co-flocculation which leads to non-floating colouring in pigment blends. As a result of the small particle size of the deflocculated pigments, high levels of gloss can be achieved and the colour strength is improved. In addition, the transparency is increased in transparent pigments and the hiding power in opaque pigments. The viscosity is reduced. In this way, the flow characteristics are also improved and a higher pigment load is possible. BYK-9076 is suitable for all pigments and is particularly recommended for stabilising acidic and neutral carbon black pigments. It is used in solvent-borne and solvent-free coatings, adhesives, and PVC plastisols. A key application area is solvent-free pigment concentrates for these applications.
