Chromium-free Degreasing Additive
LW-14 Chromium-free Degreasing Additive is a kind of colorless to yellowish transparent liquid containing powerful degreasing surface active agent, emulsifier and functional agent. LW-14 can efficiently remove aluminum surface grease, stains and natural oxidation film and results no harm to aluminum profiles. It is used for pre-treatment of aluminum profiles powder coating. It has the advantages of simple process and less aluminum consumption.
1. Bath Make-up:
Name | Quantity | Unit |
LW-14 | 15-20 | g/L |
Water | Balance | |
2. Operating Conditions:
Name | Quantity | Unit |
LW-14 | 15-30 | g/L |
Temperature | Room Temperature | |
Time | 5-10 min Depends on the surface conditions | |
3. Solution Maintenance:
1) Analyze LW-14 concentration and etching amount every day, and replenish in time.
2) It is inevitable to bring in some insoluble substances such as mechanical debris and dust in the production process, so the bath solution should be cleaned up in time.
3) Pay attention to the influence of temperature difference in winter and summer on etching amount and adjust the concentration in time to maintain the stability of etching amount.
4. Packaging and Storage:
Package: Plastic barrel (25kg/barrel,1000kg/barrel)
Storage: Suggested to store in cool, dry and well ventilated place; away from fire and heat source.
