novaform ^® FSD is the name for Frenzelit´s range of silk screen gaskets. They are mainly used for applications where with low bolt pressures a reduction of surface leakage is required. A sealing outline or coating with a thickness of 10µm to 500µm is applied on the component to be printed. It can be either a cut gasket made from a soft material, or from metal or complete components. The design of the outline is either full flat e.g. when applying layers of adhesive, or only partial, to create a line compression (see Fuji picture). This provides the opportunity to optimise the surface pressure in case of low bolt forces. The height of silk screening can be varied even within the outline itself. The silk screening compounds used by Frenzelit are determined through the relevant application, their technical values as well as colours can be modified on request.
