SOLVENTFREE AMINE-CURED EPOXY FOR WATER TANK CERTIFICATED ACCORDING TO NSF/ANSI 61, MIL-PRF-23236D
TYPE
The two-pack solventless water tank coating based on Bisphenol A epoxy resin and polyamine resin with anticorrosive pigment.
USES
Used for new water tank or maintenanceold one to prevent rust, also suitable for steel and concrete structures, such as chemical plant, bridge, power plants, inlet and outlet water pipe, water ditch, sewer etc.
CHARACTERISTICS
1.Good adhesion with steel or concrete substrate.
2.Excellent resistance to water and corrosion.
3.Good compatible with cathode protection system.
4.No VOC emissions in the coating.
5.The paint for white color obtains NSF ANSI 61 certificate, suitable for potable water tank lining

FOR AIRLESS SPRAY
NOTE
1. Adhered grease, dust and sand on substrate must be cleaned thoroughly. Steel surface must be blast-cleaned to ISO-Sa 2 1/2 or SSPC-SP-10, the roughness of surface must reach 30 microns and above.
2. Mix base and hardener according to the mixing ratio and stir thoroughly and then apply within 60 minutes.
3.Use 60:1or greater airless spray.
4. When applied, please wear gloves to avoid skin to touch, accidentally when the mouth, nose or eye touch, immediately wash with water.
5. When used inside tanks, sufficient ventilation must be provided.
6. When overcoating interval is exceeded, paint film surface must be roughened to ensure adhesion.
