Silicone- and solvent-free flow and leveling agent with air release properties for non-aqueous coatings

EFKA FL 3740 EH is a levelling agent with air release properties for nonaqueous, liquid coating systems, as well as for powder coatings and binders for powder coatings. Due to its chemical structure, EFKA FL 3740 EH modifies the surface tension of the coatings. It also eliminates or reduces cratering, fish-eyes and orange peel, improves the flow, dispersion and floating behavior, prevents air entrapment and optimizes wetting of the substrate.

EFKA FL 3740 EH is ideally suited to be used in the manufacturing of powder coatings or binders for powder coatings. For the preparation of a master batch, it is recommended to use a mixing of 9 parts of polyester resin with 1 part EFKA FL 3740. This mixture is perfectly suited for direct application in the premix and extrusion process after melting, homogenization, cooling and granulation. The drawbacks of leveling agents applied on SiO2 are avoided. In particular, pigmented and transparent powder coatings with excellent levelling properties are obtained for the production of weatherproof powder coatings.
