SIKA-R...AS is a high porous ASymmetrically designed metallic membrane. The thin layer giving the filter its performance
is coated on a coarser SIKA-R support structure. Metal membranes can be manufactured to all dimensions from SIKA-R...AX
and SIKA-R...IS. The membrane's two functions, strength and particle retention, are separated from each
other – leading to a new type of filter.
The coarser support material renders the mechanical stability without increasing the pressure drop of the filter system
considerably. This filter-active membrane was developed as a surface filter and allows pore sizes from 0.1 µm to 3 µm.
The thin coating is connected to the support structure by sintering.
SIKA-R...AS qualities differ from the known properties of SIKA-R materials in the following points
