EFKA® FL 3740 is a leveling agent with air release properties for non-aqueous, liquid coating systems, as well as for powder coatings and binders for powder coatings.

Due to its chemical structure, EFKA® FL 3740 modifies the surface tension of the coatings. EFKA® FL 3740 eliminates or reduces cratering, fish-eyes and orange peel; it improves the flow, dispersion and floating behaviour, prevents air entrapment and optimizes wetting of the substrate.

Applications

EFKA® FL 3740 is also ideally suited to be used in the manufacture of powder coatings or binders for powder coatings. For the preparation of a master batch we recommend 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.
