Metal-Flex 480

technical data sheet

DESCRIPTION AND RECOMMENDED USES: 100% solids, Dura-Coat Metal-Flex 480 is a high elongation, elastomeric, hybrid-epoxy. It is ideally suited for cavitation and abrasion, and it is completely compatible with epoxy coatings. The elastomeric aspect delivers a tough, flexible resilience while the epoxy aspect provides improved water and chemical resistance and shelf stability. Metal-Flex 480 epoxy reactivity eliminates the moisture sensitivity and toxicity associated with traditional urethanes. Metal-Flex 480 is easily applied up to 25 mils without slump.

  • It can be applied up to 25 mils without slump
  • Suitable for cavitation, corrosion and abrasion protection
  • Suitable for any substrate, steel, aluminum, concrete, bronze
  • Suitable for immersion and non-immersion service.

Application sheet

Surface Preparation
Proper surface preparation is critical to the long-term performance of this product. The exact requirements for surface preparation vary with the severity of the application, expected service life, and the initial substrate conditions. Minimum preparation is mechanical preparation St2/St3. Optimum preparation will provide a surface thoroughly cleaned of all contaminants and roughened to an angular profile between 75-125 μm (3-5 mil). This is normally achieved by initial cleaning and degreasing and then abrasive blasting to a cleanliness of Near White Metal (Sa.21/2), followed by removal of residual abrasive blast residues from the surface to be coated.

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 weight 1-parts Base to 1-part Activator. Mix thoroughly to produce an even colored and streak-free material. THINNING: Never thin.

Application
Brush: medium to stiff bristle of sufficient quality that bristles do not pull out and stick in coating (epoxy glued bristles are best).
Trim or tape to <1” nap.
Roller: use good quality 1/8” nap.

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.
