3M™ Dyneon™ Fluoroplastic PFA 6900GZ
Generic Name: 全氟烷氧基 (PFA) - 提供方: 3M Advanced Materials Division
3M™ Dyneon™ PFA 6900GZ is a 50% solids fluorothermoplastic aqueous dispersion. It is a melt-processable copolymer of tetrafluoroethylene and perfluorinated comonomers, with a melt viscosity several orders of magnitude lower than PTFE.
It can be utilized in coating system formulations and in combination with conventional PTFE dispersions, binding resins, and pigments. Dyneon PFA 6900GZ is ideal for use as a protective fabric coating and, particularly in combination with PTFE dispersions, for coating and impregnating glass fiber fabrics and metal and ceramic substrates.
