CORROSION RESISTANT COATING NRCM-204
NRCM-204 is a corrosion resistant coating material for metals and composites to protect from various environments like nitric oxide, dinitrogen tetroxide (N2O4), mixed oxides of nitrogen, concentrated nitric acid (Conc.HNO3) etc. The system is comprised of inorganic-organic hybrid network consisting of hydroxy siloxane, epoxy-amine based alkoxy silanes, crystoballite silica. Complete curing of the system is achieved by simultaneous curing of epoxy-amine and hydroxy siloxane-alkoxy silane in presence of tin based catalyst.
• Ambient temperature curing
• Corrosion resistant material to protect from harsh oxidising environment
|LSS (Al/Al) at RT, ksc||=10|
|Tensile strength, ksc||= 5|
|Tensile Modulus, ksc||5 to 15|
|Elongation (%)||70 to 120|
|Dip test of coating in Conc.HNO3 for 3 days||No Peel off|
NRCM-204 offers a highly corrosive resistant coating which can be coated over metals and composites for almost all type of corrosion which includes various acids. Conventional polymeric materials will not withstand such a highly corrosive environment.
