REVISED 10/2017

GENERIC TYPE: EPOXY REBUILDING COMPOUND; AMINE CURED 100% SOLIDS; 0% VOC’s.

DESCRIPTION AND RECOMMENDED USES: ARCOR® 8508 is an enhance wear/impact version of 8507. ARCOR® 8508 is an Epoxy filled with high density Ceramic Beads and high strength Minerals and Fibres giving it the highest level of impact, compression and abrasion resistance possible in an epoxy system. This self-­wetting formulation can be applied without a primer, can be applied at +1″ (1000 mils, 25mm) on verticals and overheads and can be levelled to a smooth finish requiring no topcoat dramatically minimising application & turnaround time.

SEE MATERIAL SAFETY DATA SHEET BEFORE HANDLING THIS PRODUCT

 

SURFACE PREPARATION: Metal surfaces are to be cleaned and degreased then abrasive blasted with chloride free abrasive. Exterior applications to SSPC SP-6 Commercial Finish minimum 4 mil profile. Immersion applications to SSPC SP-10 Near White metal, 4 to 6 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 dam­aged area. Ca be used to rebuild damaged concrete. Concrete should be degreased, neutralized, and dry.

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 (100:50). Mix thoroughly to produce and even colored , streak-free material.

THINNING: Never Thin

APPLICATION:
Use heavy plastic squeege 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 diomand tipped tools only. Grinding is possible only if done within 2 hours of application at 77°F (add 1 hour for each 10°F below 77°F, subtract 1 /2 hour for each 10°F above 77°F).

APPLICATION TEMPERATURE:
Material: keep between 55 and 95°F (17-35°C). Substrate: keep between 45-105°F (7-40°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.

OVERCOAT/CURE TIME:
Recoat as soon as possible while material is still soft, within 2-4 hours at 77°F. 25°C. Max overcoat is 12 hours at
77F(25C). If overcoat window is exceeded abrade surface with course sandpaper, grinder or brush blast. Full cure before immersion 36 hours at 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 or MethylEthylKetone (M.E.K.). Use 98%+ lsopropyl Alcohol in solvent controlled 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.
