Micava 496 High Crosslinked Polymer/Flake Composite is a self-levelling two-component phenlic epoxy vinyl ester resin composite which filled of flake materials. Micava 496 has excellent wetting properties, can be adhered to metals, concrete, ceramic, and glass-lined. Micava 496 also has properties of strong anti-chemical corrosion, anti organic and inorganic acid, and excellent resistance to most organic solvents.

- Surface Treatment:
Sandblasting the steel surface with chlorine-free abrasive. For external application, the surface should reach SSPC SP-10 standard, close to the white metal treatment standard. After sandblasting the surface, repair surface as soon as possible to prevent surface oxidation, then repair the damaged area properly.
Resin :hardener mixed rate is 100:0.5~2 by weight. When the operating temperature is higher than 28℃, the recommended resin : hardener mixed rate is 100:0.5-1%. When the operating temperature is below 28℃, the recommended resin : hardener mixed rate is 100:1.5-2%. When the operating temperature is higher than 15℃, user can add hardener according to the size of the device and operating requirements.
Do not dilute.
- Application tools:
Stir the resin first, then mix with the hardener well (about 3 minutes). Use a trowel or other tool to flatten brushing.
- Application temperature:
Material temperature: Keep at 55-95℉ (13-35℃)
Substrate temperature: Keep at 45-105℉(7-40℃)
The temperature difference between the substrate and the coating must not exceed 10℉(5℃)
- Re-coating/curing time:
Recoating in the time when material were still soft, within two hours, at 77ºF (25ºC). If the recoating time has been exceeded, polish the surface with sandpaper, grinding, or blasting.
Wash with methyl ethyl ketone or similar products.
