    Formulated Specifically for Castings Impregnation

    RC-80ND is a specially formulated Two-Part thermo-setting resin designed for the impregnation of all types of micro- and macro-porous, ferrous and non-ferrous alloy castings as well as other metal and non-metal parts.  RC-80ND is a result of IMPCO's ongoing research and development efforts to provide users with a superior sealing impregnating resin with outstanding physical and chemical resistance properties.  Cured, RC-80ND impregnating resin is resistant to fuels, oils, alcohols, glycols, solvents, salts, mild acids and freons, and it has excellent dielectric properties.  RC-80ND is uninhibited by copper based alloys.

    Operating Economies and Problem-Free Cure

    The low viscosity and high polarity of RC-80ND impregnating resin ensure deep penetration, low materials consumption and a lower impregnating cost per unit.  Its inherent flexibility provides excellent pressure and temperature resistance, as well as high resistance to physical and thermal shock.

    RC-80ND impregnating resin is designed and formulated for short cycle operations of 10 to 20 minutes.  It is easily cleaned and rinsed from the part surface.  Parts processed with RC-80ND come out clean, completely cured, and "job ready" for immediate testing or use.  Overall part quality is improved through the virtual elimination of bleedout problems on the part surface.


    Water Washable

    RC-80ND is biodegradable and washes in plain water.
