Teflon PTFE is a kind of non-stick plastic material, so how we can glue it to the suface of another material ?

In order to bond standard PTFE to another surface such as stainless steel or plastic or rubber products, a process called "etching" is required.

Typical applications would include the lining of chemical process tanks or other equipment used in caustic environments. When bonding is needed, sodium ammonia etching is usually the most economical answer. This process uses of a mixture of sodium and ammonia that is formulated to create a bondable surface both quickly and efficiently. Sodium/ammonia etching service complies with all applicable commercial, military & federal specifications for the surface treatment of all fluoropolymers including: PTFE (Teflon), PFA, FEP, ETFE, PCTFE, PVDF, PVF, & ECTFE.

• Note: Etched surfaces will discolor to a brown appearance.
• Etched PTFE is able to be bonded after etched treatment.
• Uniform treatment on one side or two sides (surface treatment only.)
