Product Introduction
SY-8303/8309 is a water-soluble anionic fluorinated surfactant with good water solubility. At a low concentration such as 0.1% (100ppm), the surface tension of the aqueous solution can be reduced to a low level (20 dynes/cm), which can greatly improve the wetting and leveling properties of the coating.
The surfactant has low foaming and good chemical stability. It can be stable in acid and alkali systems of a certain strength, so it can be used as a long-term low-foam wetting and leveling agent. It can be used in architectural coatings, floor waxes, industrial paints, wood coatings, etc. Especially in the application of water-based acrylic and water-based polyurethane coating systems, such as wood coatings, it is very effective in eliminating shrinkage cavities and frame effects;
