- Surface Preparation
- Metal surfaces are to be cleaned and degreased then abrasive blasted (or Bristle Blast) with chloride free abrasive. Exterior applications to SSPC SP-10 Near White metal finish minimum 3 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 surface. For larger surface areas with ferrous metals if need prime with EE-10, EE-11 Prime or S-30 Prime.
- Mixing
- Thoroughly mix Activator into Base with mixing stick scraping sides and bottom of container or mixing board. Mix by Volume 1-part Base to 1-part Activator. Or by Weight 1-part Base to 1-part Activator (100:100). Mix thoroughly to produce an even colored, streak-free material.
- 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 putty knife or plastic applicator. If a 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 quality diamond tipped tools only and is best done as soon as product is stable and before full cure. Sanding or Grinding is possible only if done within 6 hours of application at 77ºF (add 1 hour for each 10ºF below 77º, subtract 1/2 hour for each 10ºF above 77ºF). Large holes and cracks can be bridged with fiberglass, polyester or metal cloth.
- Application Temperature
- Keep between 55 to 95ºF(17 to 35ºC). Substrate: Keep between 45 to 105ºF(7 to 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. Note that heated product will have less working time and faster cure.
- Overcoat / Cure Time
- Recoat as soon as possible while material is still soft, within 2 to 6 hours at 77ºF. 25ºC. If overcoat window is exceeded abrade surface with course sandpaper, grinder or brush blast. Wipe with Acetone or similar. Full cure before immersion 36 hours at 77ºF. Add 1-day additional cure time for each 10ºF below 77ºF. Subtract 6 hours of cure time for each 10ºF above 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
