Description
7301/7303 is a nonionic fluoro surfactant that provides exceptionally low surface tension in aqeous or sovlent-based products, enabling better wetting, spreading, leveling to coating system. In the aqueous solution, it can effectively reduce the suface tension to 25dyn/cn by very low dosage.
7301/7303 is versy stable in the acidic, basic, brine and hard water environments. It is compabiltle with most of the resin and additives. So it can solve the wetting defects by replacing or combined with traditonal addtives.

Application method
The typical loading dosage is around 0.1-0.2%. It is strongly recommended to diliute the product with alcohol(IPA) beforing adding into the sytem. Due to its high efficiency, good dispersion is important to achieve its function.
