Updated May 2020



DESCRIPTION AND RECOMMENDED USES: ARCOR™ EE-93 is a solvent free, two component rebuilding compound designed for high abrasion, erosion and cavitation environments. EE-93 is a Novolac Epoxy filled  with spherical cubic zirconium giving it the highest level of chemical, heat and abrasion resistance possible in an epoxy system. This self-wetting formulation can be applied without a primer and can be levelled to a smooth finish requiring no top coat minimizing application & turn-around time.

SURFACE PREPARATION: Metal surfaces are to be cleaned and degreased then abrasive blasted with chloride free abrasive. Exterior applications to SSOPC SP-10 Near white finish minimum 3 mil profile. Immersion applications to SSPC SP-5 White metal, 3 to 5 mil profile. Grind flat all burrs, weld seams, radius sharp edges. Fresh blasted surfaces to be rebuilt as quickly as possible to prevent oxidation of the surface and allow time for proper rebuilding of the dam- aged area.

MIXING: Thoroughly mix Activator into Base with mixing stick scraping sides and bottom of container or mixing board. Mix by volume 2 parts Base to 1 part Activator. Or by weight 2 parts Base to 1 part Activator. (100:43). Mix thoroughly to produce and even colored, streak-free material.

THINNING: Never Thin

APPLICATION: Use heavy plastic squeegee or putty knife. Work material into profile of substrate to achieve maximum adhesive and to remove any entrapped air. Contour to correct form with putty knife or plastic applicator. If mold or form is used be sure  to coat its surface with a release agent to prevent adhesion of the material. Machining is possible using diamond tipped tools only. Grinding is possible only if done within 2 hours of application at 77ºF (add 1 hour for each 10ºF below 77ºF, subtract 1/2 hour for each 10ºF above 77ºF).

APPLICATION TEMPERATURE: Material: keep between 55 and 95ºF (17-35ºC). Substrate: keep between 45-105ºF (7-40ºC). The difference in tempera- ture of the substrate and the material should never exceed 10ºF, 5ºC. Substrate shall be a minimum of 5ºF (3ºC) above dew point. Do not apply if relative humidity exceeds 90%. If necessary heat the metal prior to surface preparation using electric heater or heat lamp. Never use gas, oil or kerosene heaters as they will leave a greasy residue on metal sur- face. For best results keep all material in warm area overnight (75ºF+) for ease of mixing. If necessary Base component of material can be heated by microwave for 30-45 seconds for a 1 KG Base unit or by warm water bath. Heat Activator  by warm water bath only. If necessary let material cool before application.


Re-coat as soon as possible while material is still soft, within 2 hours at 77ºF. 25ºC. If overcoat window is exceeded abrade surface with course sandpaper, grinder or brush blast. Full cure before immersion 36 hours at 77ºF. Force Cure with heat for best performance for 1 hour at 200ºF, 93ºC, 12 hours at 120ºF,  49ºC.

CLEAN UP: Clean tools immediately after use with Acetone, M.E.K.. Use ARCLEAN or Isopropyl Alcohol in solvent con- trolled environments.

WARNING: Base contains epoxy resin. Activator contains alkaline amines, a strong sensitizer. May cause skin irritation, sensitization or other allergic responses. Use with good ventilation, particularly if heated or sprayed. Prevent all contact with skin or eyes. Wear protective clothing, goggles, gloves or barrier creams. Keep containers closed when not in use. Wash thoroughly after handling. In case of skin contact immediately wash with soap and water. In case of eye contact, flush with water for 15 minutes. If irritation persists seek medical attention.
