ARCOR 8505
Updated May 2020



DESCRIPTION AND RECOMMENDED USES: ARCOR™ 8505 is a solvent free, (100% solids, 0% VOC), blend of ceramics and toughening agents which provides excellent wear, and enhanced adhesion, without the need for a primer. ARCOR™ 8510 is designed to be applied in one thick coat, up to 1.0+”(25+mm) vertical. It is an ideal material to protect areas of fluid flow equipment that are subjected to high wear. Good all-around chemical resistance. Insulates against Bi-Metallic Corrosion. Excellent impact resistance. Excellent resistance to cavitation. Similar to our 2211 & EE-95 in application, look and feel, but with lower temperature limits and chemical resistances.

SURFACE PREPARATION: Metal surfaces are to be cleaned and degreased then abrasive blasted with chloride free abrasive. Exterior applications to SSPC SP-10 near white metal finish minimum 4+ mil profile. Immersion applications to SSPC SP-5 White Metal, 4+ 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. For larger surface areas with ferrous metals apply a primer layer of ARCOR™ 8518 to prevent oxidation of the surface and allow time for proper rebuilding of the damaged area.

Concrete surfaces should be degreased if oil and grease contamination is present. Degreased surface shall be high pressure washed, acid etched and high pressure washed again so surface is clean and free of all grease, oils and surface laitance. Existing coatings should be abrasive blasted to clean concrete. Prime, if needed, with ARCOR™ 8518.

MIXING: Thoroughly mix Activator into Base with mixing stick or drill with low speed mixing blade scraping sides and bottom of container or mixing board. Mix by Volume 1 parts Base to 1 part Activator. Or by weight 100 grams base to 100 grams activator. Mix thoroughly to produce an 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 adhesion and to remove any entrapped air. Contour to correct form with plastic applicator or putty knife. If mold or form is used, coat its surface with a release agent to prevent adhesion of the material. Machining is possible using carbide tipped tools. Machining & Grinding is best done within 8 hours of application at 77°F, 25°C (add 1-1/2 hour for each 10°F below 77°, subtract 1 hour for each 10° above 77°F). Machining & Grinding can be done after this time, but the material does become very hard and will rapidly wear bits and discs. Large holes and cracks can be bridged with glass or metal cloth.

APPLICATION TEMPERATURE: Material: Keep between 55 to 95°F (17 to 35°C). Substrate: keep between 45 to 105°F (7 to 40°C). the difference in temperature of the substrate and the material should never exceed 10°F, 5°C. Substrate shall be a minimum of 5°F (3°C) 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 surface. For best results keep all material in warm area overnight (75°F+) for ease of mixing. If necessary Base component of material can be heated by microwave for 30 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. Application onto surfaces above 77F (25C) may cause the material to sag/slump. This will increase as temperatures increase, so single coat thickness must be reduced.

OVERCOAT / CURE TIME: Re-coat while material is still soft (fingernail indent), between 2 to 8 hours at 77°F, 25°C. If overcoat window is exceeded abrade surface with course sandpaper, grinder or brush blast. Full cure before immersion 72 hours at 77°F (25C). Add 1 day additional cure time for every 10°F below 77°F. Subtract 15 hours of cure time for each 10°F above 77°F. Force cure with heat for best performance for 1 hour at 200°F (93°C), 12 hours at 120°F (49°C).

CLEAN UP: Clean tools immediately after use with Acetone, M.E.K. or similar.

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.
