Special Properties and Uses

MODAFLOW LAMBDA is a unique acryl-silicone polymer hybrid technology flow promoter combining individual efficiencies from high end acrylic as well as silicone leveling performance. It is highly compatible in all non-aqueous clear coat and topcoat formulations and outperforms surface characteristics such as

- gloss


- sharpness & brilliancy

- anti orange-peel effect.

It is efficient at low dosage levels and incorporates easily in many solvent borne resin types including high solids and ultra-high solids. Further it can be applied in solvent free and radiation curing systems.MODAFLOW LAMBDA demonstrates superior balance of compatibility and effectiveness compared to traditional silicone or acrylic flow and leveling additives in Automotive OEM, refinish as well as industrial coatings. Due to its high hydroxyl functionality, MODAFLOW LAMBDA may be co cross-linked in stoving or 2K systems and does not show a decrease in interlayer adhesion. In multiple layer systems the stoving temperature should not exceed 130 °C to ensure a good recoatability.

The recommended dosage level is 0.05 % calculated on total formulated coatings as a starting point and optimum dosage range is between 0.05 % - 0.3 %. In some cases the dosage could be increased up to 0,5 %.
