APFS 27-40

Fluorinated surfactant. It acts as a wetting- and levelling agent. It exhibits stability, effectiveness in hard water, better wetting, spreading, and penetration. It is very effective on hard to wet surfaces such as plastics, oily or waxy substrates, and fluoropolymer or silicone treated fabrics. It reduces the surface tension of aqueous solutions and emulsions to as low as 20 dynes/cm. Possesses stability in concentrated acids, bases and oxidizing solutions. Low use levels required (0.01-0.1%). Provides far greater surface tension reduction that can be achieved with either hydrocarbon or silicone based surfactants. Used in waterborne applications. In coatings, it improves film uniformity, enhances adhesion, and reduces pinholes and craters. In finishes and polishes, it reduces droplet resulting in less spotting, and smoother and more even films. Also used in floor polishes/ strippers and paints. Complies with TSCA (USA).
