Is it possible to use PTFE spray instead of PTFE coated fiberglass fabric?

PTFE spray is used only in those places where PTFE coated fiberglass fabric/tape is not possible to be employed. It is often used in domed machines - the cutting knife (wire-off) is sprayed with it to protect the blade from sticking / wrapping foil during cutting.

What is the difference between dry and wet PTFE?

Dry PTFE does not leave stains on surfaces, is non-stickable and provides glide. It creates a dry layer on the surface resistant to water, oil and grease. It does not contain silicone, it does not absorb dust, easy and convenient to use.
Wet PTFE (PTFE grease) is used as lubricant for longlasting protection and for applying grease to moveable parts. It is used for mechanisms such as locks, pendants, couplings, chains, rods, gears, precision tools, etc.. It cleans, lubricates and protects the surfaces from oxidation, PTFE grease can be used at a temperature of -10 to 180 degrees Celsius.

What can PTFE spray be used for?

Dry PTFE is used wherever silicone or wet agents are not recommended. It is employed to reduce friction.
Wet PTFE (PTFE grease) is used for mechanisms such as locks, pendants, couplings, chains, rods, gears, precision tools, etc..

Why should PTFE spray be used?

Dry PTFE is used to reduce friction between mechanisms. It creates layer on the surface which is resistant to water, oils and greases.
Wet PTFE (PTFE grease) is used to secure mechanisms. The product has very good both cleaning and lubricating properties as well as protecting surfaces against oxidation. PTFE grease can be used at a temperature of -10 to 180 degrees Celsius.

How long does PTFE spray keep on a surface?

PTFE spray creates layer on sprayed surface - protective coating. It depends on the working conditions.
