| Teflon PTFE 305A |
 |
Teflon PTFE 305A fluoropolymer resin is a negatively charged, hydrophobic colloid containing approximately 60%(by total weight) of 0.05 to 0.5 mm polytetrafluoroethylene(PTFE) resin particles suspended in water.
A milky white liquid, Teflon PTFE 305A also contains approximately 8%(by weight of PTFE) of a nonionic wetting agent and stabilizer.
Viscosity at room temperature is approximately 20 cP.
Nominal pH is 10. Compared with other grades of PTFE dispersions,
Teflon PTFE 305A is used as a prime coat for high dielectric strength glass fabric.
Teflon PTFE 30B is then normally used for subsequent topcoats. |
