EnhancedResistance to InorganicAcids

In our continuing program of developing surface
technologies, Restek introduces this line of highly
corrosion resistant fittings
and tubing. Silcosteel
®
-CR*
coating is optimized to
enhance resistance to
hydrochloric, sulfuric, and
nitric acids (Figure 1).
Tubing and fittings used in
the presence of these
destructive acids require frequent inspection and
replacement. The Silcosteel
®
-CR coating, applied to
widely-used Parker A-lok fittings and seamless 316L
stainless steel tubing, adds an order of magnitude of
protection against corrosive attack.
Silcosteel
®
-CR treatment involves a unique deposi-
tion process that completely covers the exposed sur-
face of the tubing or fitting and prevents contact
between the acids and the surface. The Silcosteel
®
-
CR coating itself is insoluble in these acids, and its
application provides an unmatched layer of protec-
tion to stainless steel.
Custom Silcosteel
®
-CR coating service is available.
Please contact our technical service department or
your local Restek representative to inquire about
having your items Silcosteel
®
-CR protected.
