| Résumé : |
A new fluoropolymer emulsion has been studied, which exhibits excellent weather resistance and reduces solvent emission. As a result of the introduction of a vinyl ether type macromonomer with a hydrophilic long chain, fluoroethylene and vinyl ethers could be stably copolymerized in water without hydrophilic cosolvent and this copolymer has an alternating sequence. Moreover, by optimizing emulsifier and polymerization conditions, an emulsion possessing high non volatile matter content (50 % by weight), suitable average particle diameter (0.15 μm) and mechanical/chemical stability for pigmentation, has been achieved. It can be used for preparation of architectural paint in a similar manner as conventional acrylic emulsions. The fluoro-emulsion film retains more than 90 % of its initial gloss after sunshine weather-o-meter exposure for 5,000 hours. In this paper the typical properties of this fluoropolymer emulsion (e.g. polymer structure, emulsion properties and application examples) are reported. |
