ARCOR Epoxy Technologies Company Logo
ARCOR® 8507 is an Epoxy Rebuild designed to offer similar performance as our 8506 variant in terms of resin and amine composition. However, in addition to the small mesh Ceramic Beads present in 8506, ARCOR® 8507 incorporates larger mesh Ceramic Beads and high-hardness mineral fillers, resulting in a denser product with enhanced capabilities to withstand impact, abrasion, and compressive forces. This self-wetting formulation can be applied without a primer, even at a thickness of up to +3/4" (750 mils, 18.75mm) on vertical and overhead surfaces. It can be smoothly leveled, eliminating the need for a topcoat, thereby significantly reducing application and turnaround time. With a convenient 1:1 Mix Ratio by volume, ARCOR® 8507 is easy to use in the field. It offers a similar application, look, and feel as our EE-94, but with lower temperature limits and different chemical resistance properties. ARCOR Epoxy Technologies can tailor make or reformulate the product to suit customer needs. Please reach out if you need a custom formulated product!

Cure Method
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 damaged area.
Mixing

Thoroughly mix Activator into Base with mixing stick scraping sides and bottom of container or mixing board. By Volume 1:1. By Mass 1 part Base to 7/8 part Activator. Or 100 grams Base to 90 grams Activator. Mix thoroughly to produce and even colored , streak-free material.. Mix thoroughly to produce and even colored , streak-free material.

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 77ºF (add 1 hour for each 10ºF below 77ºF, subtract 1/2 hour for each 10ºF above 77ºF). Coal Crushers, Coal Chutes, Pumps, Impellers, Propellers, Valves, Hydro-Wheels, Pipe Elbows..
Application Temperature
keep between 55 and 95ºF (17-35ºC). Substrate: keep between 45-105ºF (7-40ºC). The difference in temperature 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 surface. 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.
Overcoat / Cure Time
Recoat 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 M.E.K., Acetone, 98+% Isopropyl Alcohol or similar
