2 in 1 Chemical

This chemical is very economically that removes heavy rust and medium oil, mild scale. Metal cleaner DR-SP-410 is 2 in 1 chemical used for those do not have enough space for 8th tank process. Concentration of this chemical is 20-25% V/V and for time 20-30 minutes.

Product Description Concentration Time
Metal Cleaner
DR-SP-410
Economically, very effectve for degreasing & derusting 25 to 35% at RT 20-25 min (Depends upon material conditions)

Activation

Activation chemical does grain refinement and gives compact crystal structure, uniform coating of Zinc phosphate.

Metal Cleaner
PDR-10 SP
Alkaline base 0.5% W/V 1 min Room temp.

Conversion coating

We provide three different type of conversion coating for ferrous surface.
  • 1 Zinc phosphate coating
  • 2 Iron phosphate coating
  • 3 Tricationic phosphate coating

Product Description Concentration Time Temperature
Metal Cleaner
ZLP-40
Medium weight zinc phosphate 3 - 5% V/V 20-25 min Room Temp.
Metal Cleaner
ZLP-60
Light weight zinc phosphate 3 - 5% V/V 10-15 min 60 to 70°C
Metal Cleaner
ZLP-80
