BYK-7420 ES

Liquid rheology additive for aqueous and water-reducible coating systems for improving anti-sagging and anti-settling properties. The additive is also especially suited for manufacturing aqueous pigment concentrates. BYK-7420 ES creates thixotropic flow behaviour. Post-addition is possible. After being stirred into the coating system, the additive generates a three-dimensional network structure. The resulting thixotropic flow behaviour is highly suited for preventing sedimentation and syneresis and increasing the anti-sagging properties without impairing leveling. The additive is liquid and therefore easy to handle. It is not necessary to specifically adjust the pH value or control the temperature during incorporation.
