selection guide Overview Diferent septa material for LC and GC applications There are many diferent types of materials used to produce the septa found in LC and GC vial caps. This document will provide you with the technical guidance you need in order to make the right selection. Choosing the right septa
-
A Shield Against Chemical Attack and Biofilm Buildup. Teflon™ fluoropolymers offer a nearly universal chemical resistance. They produce a smooth, low-surface energy layer that resists biofilm buildup and facilitates their use in many applications within the food/beverage, chemical processing, and semiconductor manufacturing industries.
-
Teflon™ industrial coatings work on carbon steel, aluminum, stainless steel, steel alloys, brass, and magnesium. Teflon™ fluoropolymer resins impart high temperature, chemical, and corrosion resistance. Chemours has developed the next generation of Teflon™ PTFE dispersion products which offer a practical method to coat or impregnate resins.
-
Capacitors that are shielded in dip tubes of high-purity Teflon™ PFA resins monitor fluid levels in BCD tanks. Other sensor designs detect chemical flow through tank or pipe walls also made with Teflon™ PFA. Resins used to jacket sensors connecting electrical cables offer improved insulation, fire resistance, and electrical performance.

Apr 17, 2019 · Except enhancing the anticorrosion properties, nano-ZnO in the coating could also improve its UV resistance. When exposing alkyd-based water borne coating under UV-radiation for 110 h, there were several cracks and pinholes on the surface, while for the ZnO-based nanocoating under the same condition, no cracks were observed (Dhoke et al., 2009
