Résumé : |
Fluorinated resins are known for high performance, particularly in long term, exterior durability. Fluoroethylene vinyl ether or FEVE resins, a family of fluorinated resins, have a unique alternating copolymer structure allowing them to be dissolved in solvent, as well as emulsified in water for formulating liquid coatings. As environmental initiatives are becoming less compulsory and industry is taking proactive measures to protect the environment, waterborne and high solids paint is ever increasing in demand.
Studies encompass both 1K and 2K formulations and focus on dispersant type, coalescing agents and methods of altering gloss. Results of the many tests that measure critical properties of high performance coatings will be presented. Testing includes water resistance,
chemical resistance, vapeur permeability, solar reflectance properties and mould resistance along with corrosion resistance and accelerated weathering. Formulations based on blends of FEVE resins with other polyols, like acrylic polyols and polyester polyols will also be explored. |
