    Fluorination process

    Gas-phase fluorination is an innovative process for long-term activating of a polymer surface.

    Fluorine is the most electro-negative element in the period system. It can easily be used with virtually all in-organic and organic compounds to produce a controllable reaction at room temperature and without the need for any further activation. This method produces an active surface for a long period of time, to which mechanical and chemical bonding is possible.

    A reproducible, dry chemical reaction occurs during the fluorination process, in which fluorine atoms replace the hydrogen atoms in the uppermost monomer layer of the polymer chain.

    The long-term stability of the fluorination process lasting several months, is far more durable than the results of other pre-treatment systems.

      For several years this process has been used in the industry to activate the surface of components before they are painted or printed.

    In our batch reactors, three-dimensional components are treated in a chamber made from chrome-nickel steel that is loaded with the components to be fluorinated and activated.

    This is followed by the actual fluorination process, in which a gas mixture of fluorine and nitrogen is passed into the reactor. The nitrogen serves as an inert gas to slow down the reaction rate. After a few minutes, activation of all the component surfaces, including all undercuts and blind holes, is complete. In order to be able to open the reactor, the fluorine concentration must be reduced below the threshold limit value. This is achieved by purging with air a number of several times. The residual amounts of fluorine present in the gas after purging are converted with CaCO3 into CaF2 in an absorption tower. The calcium fluoride that is produced is harmless and can be further processed as a normal industrial product or disposed off.
