Dry oil-, grease- and silicone-free PTFE-based lubricant and release agent.
Features :
KONTAKT CHEMIE Kontaflon 85 is a completely dry lubricant. The lubricating solid particles consist of PTFE (polytetrafluoroethylene).
Compared with simple PTFE powder sprays, KONTAKT CHEMIE Kontaflon 85 contains a binder who bonds the PTFE particles firmly to the surface.
This binder, together with the PTFE particles, forms a very thin non-wear film.
Binder and PTFE have very good heat resistance.
In the given temperature range there are only a very few chemicals (alkali metals and hot, concentrated sulphuric acid) which attack the lubricant film.
From this viewpoint, KONTAKT CHEMIE Kontaflon 85 differs from socalled gliding coatings, of which the thermal and chemical resistance is determined by the properties of the used resin.
KONTAKT CHEMIE Kontaflon 85 can be used in the vicinity of or on sensitive materials : textiles, paper, cardboard, wood.
It can be used at extremely low temperatures (e.g. liquid nitrogen).
It can also be used on sensitive plastics and in presence of aggressive chemicals.
When very thin, non-contaminating lubricating films are required, e.g. for the lubrication of the ejector pins in plastic injection moulds.
PTFE has a very low static/gliding friction ratio; it is very effective therefore at inhibiting back gliding.
KONTAKT CHEMIE Kontaflon 85 is used as a temperature-resistant mould release agent in plastics and elastomer processin
