● Features
- As non-silicate based degreasing agent, Dyna DM-260 is a low foamy ferrous and nonferrous alkalic degreasing agent which does not cause surface corrosion and stain.

● Additional Information

▶ The directions
- Use concentration: 5-7 % aqueous solution
- Working temperature: 60-80℃
- Washing method: Spray, deeping

▶ The method of administration of fat removers

1. Checking concentration (Alkali measurement)
- Pour treatment liquids 10㎖ using PIPET into the tri-flask, then pour 3-5 drops of PHENOL PHTHALEINE indicator and titrate as 0.1N - Hcl. When pink is disappeared, it is the terminal. The alkali degree is the multiple numbers of required 0.1N - Hcl's milliliters and FACTOR.

2. Checking fat removal
- When drives cold water to material that finishing fat removal, if water drops don't roll down, it is justifying in thinking that finish fat removal.

3. Supplement of fat removers
- Treatment liquids concentration (Alkali concentration) will fall down because of continuous treatment. If the first concentration maintains, fills up the DM-260.

4. Exchange of treatment liquids
- There is a limit of Alkali-type fat removers generally. When there are fats over activator's emulsifying ability in treatment liquids, if filled up fat removers, fat removed ability fall down remarkably. So change treatment liquids if removal time is doubled than the first time.
