Preparation and Properties of Waterborne Side-Chain Fluorinated Polyurethane

Article Preview

Abstract:

Waterborne side-chain fluorinated polyurethanes were prepared from fluorine-containing polyether polyol, N210, isophorone diisocyanate (IPDI) as main materials through self-emulsified method. The factors on FWPU, including the particle size and distribution, solid content, the acid and alkali resistant properties of emulsion film, were investigated. The results indicated that the particle size of fluoronated polyurethane dispersion was small, and dispersion had good stability. The emulsion film had better chemical resistant properties.
