imgboxbg Product description
Capstone® FS-30 is a general-purpose water-soluble fluorine-containing polyoxyethylene ether nonionic surfactant, which can provide efficient surface activity at a very low dose.
Capstone® FS-30 does not contain any VOC (Volatile Organic Compound), APEO (alkylphenol polyoxyethylene ether), is not flammable, and is compatible with any ionic surfactant.
Capstone® FS-30 is stable in ordinary, acidic, salty and hard water environments.
Because it is stable in a wide range of pH environments, Capstone® FS-30 is an excellent wetting and leveling agent suitable for use in various aqueous systems.
Capstone® FS-30 can reduce the carry-out of electroplating tank applications to improve electroplating efficiency; used in various coating formulations to eliminate surface defects of paint films; also used in cleaning formulations to reduce surface tension.
