How to coat PTFE Fabric Substrates

 

PTFE Aqueous Dispersion is also suitable for coating on impregnating of other materials, such as glasscloth.Conventional dip or flow techniques can be used for coating or impregnating other products.

 

With PTFE Aqueous Dispersion.The resins particles can be consolidated by heat into a coherent matrix or coating on left as particles to influence the properties of a finished product. A continuous PTFE resin coating on woven fabric can be made by dip coating.Successive passes must be used to build up thickness slowly and without cracks.PTFE Aqueous Dispersion fluoropolymer provides good rewetting on each pass and void-free buildup suitable for more demanding electrical and chemical service applications.Each coating layer is usually dried to remove water (typically at 120℃)baked to remove the crystalline melting point of the resin particles (approximately 337).A calendering process maybe used after the fabric has been baked in applications where multiple passes of PTFE aramid fiber, or other high-temperature resistant fibers must be used.

 

The excellent shear stability of PTFE Aqueous Dispersion may also provide increases in productivity, yield and quality.Other solid or liquid ingredients can be added to PTFE Aqueous Dispersion to provide specific processing or finished product behavior.
