Degreasing

Removal of oil grease, carboxides from ferrous surface. Metal cleaner DGA-110 chemical is alkalline degreasing powder. Metal cleaner LCA-210 is liquid acidic chemicals.

Product	Description	Concentration	Time
Metal Cleaner DGA-110	Low foaming, remove oil grease	5% Hot at 80°C 10% Cold at Room Temp.	15-20 min
Metal Cleaner LCA-210	Remove oil grease and light rust	20 to 25% V/V at Room Temp.	15-20 min
Metal Cleaner LCA-220	Remove Oil grease, Scale, and Light rust	20 to 25% V/V at RT	15-20 min

Derusting

Derusting chemical removes rust scale from ferrous surface.

Product	Description	Concentration	Time
Metal Cleaner DRP-310	Remove rust, scale	20 to 25% at RT	20-30 min (Depends upon material conditions)
Metal Cleaner DRS-320	Remove rust, mild scale	20 to 25% at RT	20-30 min (Depends upon material conditions)
Metal Cleaner DRP-330	Remove heavy rust, scale and oxide	20 to 25% at RT	20-30 min (Depends upon material conditions)
Metal Cleaner DRH-340	Highly acidic base deruster	20 to 25% at RT	20-30 min (Depends upon material conditions)

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 8^th 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.

Product	Nature	Concentration	Time	Temperature
Metal Cleaner PDR-10	Acidic Base	0.5% W/V	1-2 min	Room Temp.
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	Light weight zinc phosphate	3 - 5% V/V	10-15 min	75°C
Metal Cleaner LIP-30	Light iron zinc phosphate	3 - 5% V/V	5-10 min	Room Temp.

Iron phosphate does not require activationprocess. Nano coating doesnot require distilled mineral water to make the bath.

Passivation

seals the pores of phosphate coating. We provide three type of chemical.

Product	Nature	Concentration	Time	Temperature
Metal Cleaner Passi	Liquid passivation	0.1% W/V	1 min	Room Temp. to 75°C
Metal Cleaner CF	Chrome free passivation	0.1% W/V	1 min	Room Temp. to 75°C
Metal Cleaner Alkaline	Alkaline Base	0.5% W/V	1 min	Room Temp. to 75°C
