PRODUCT DESCRIPTION
2K Benzo is a solvent paint based on Polyurethane. It has excellent adhesion on the galvanizing iron substrate, excellent protection for both interior and exterior applications. It has high chemical resistance, good heat resistance, anti-corrosion from water, oil, and UV resistance.
USAGE
2K Benzo use for a primer on the metal surface aims to enhance adhesion on the substrate in the interior or exterior condition and even in the harsh condition. It matches with steel that is used in the constructions such as houses, factories, machines, tower bridges, vessels and so on
COLOR
Reddish-brown (2KE9), gray (2KE8).
DENSITY
1.5 ± 0.02 kg/litter (denpend on color)
VOLUME SOLID
Volume solid: 60± 2%
PRE-TREATMENT SURFACE
The metal surfaces must be clean, dry and free of oils, rust and other contamination. The surface preparation meets ST2.0, ST2,5 or SA 2.0, SA 2.5 Standard.
Notice: The primer must be approached within 1-3h after completion of the surface preparation to prevent the yellowing phenomenon and abrasive corrosion.
EQUIPMENT
- Brush, roller.
- Sprayer:
  • Pressure at nozzle : 100 - 150 kg/cm2(1 kg/cm2 ≈ 0,98 bar ≈ 14,2 psi) 
  • The distance between nozzle and substrate is approximate 0
