DESCRIPTION AND RECOMMENDED USES: Dura-Coat Chemical 200HT-F is a brush-applied, 100% solids, fast curing coating formulated with Novolac Epoxy resin and filled with ceramic microspheres for superior abrasion protection. It offers excellent chemical resistance in the presence of highly aggressive caustics and acids. It withstands temperatures up to 230 °C in immersion conditions.
Application is easy using a brush, roller, or airless spray equipment.
• Can be applied up to 1 mm without sagging
• Suitable for any substrate such as steel, bronze, aluminum, and concrete
• Ideal for protection against corrosion and abrasion
This product complies with FDA regulations, for direct food contact specifically FDA 21 CFR 175.300 and FDA 21 CFR 175.105.

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 2-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.
Airless Spray: 45:1 or larger with TIP 529-535, pressure 5,000psi +. Temperature 50°C (122°F).
Plural Component Airless: Gracco Xp70 or equivalent, heated to 43°C (109°F).
Robotic Application: Robotic coating application on internal girth welds using rotatory atomizer.
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.
FDA COMPLIANCE: This product complies with FDA regulations, for direct food contact specifically FDA 21 CFR 175.300 and FDA 21 CFR 175.105.
