With the continuous development of modern technology, most of the products have greatly improved, and now Dacromet metal coating has become a new type of anti-corrosion coating that people like very much. Now let's talk about how to distinguish dacromet coating True and false.

First, the selection of good flake zinc powder, is to obtain a good Dacromet coating an important condition. It is at this point that there is a problem with fake Dacromet.

Second, the observation method: Because dacromet coating solution selected zinc, is quite small, non-naked eye can directly see clearly. Therefore, in order to confirm the actual situation of the zinc powder used, we must use tools to analyze and judge. You can use the microscope to observe, do not have to use a microscope with a large magnification, as long as you can see clearly on it. By looking at the washed zinc sinking in the bottom of the cup, you can learn about the choice of coating zinc in the details. Made of flake zinc powder, made, due to the performance of the import is not good, if more solid, large diameter film, or post-processing is not done, will also be observed in the use of water washing, the precipitation soon appeared, The use of this powder for dacromet is not satisfactory and the coating made with this powder is of poorer quality, but such flake powder can be used in other aqueous coatings.

Instructions and attention:

1. Dip coating,Spray coating etc.

2. It should be stirred fully befor usage; distilled water or deionized water can be used to adjust viscosity ;Operating viscosity:30-60s.

3. When the environment humidity higher than 85%,can add certain industrial alcohol to adjust viscosity

4. Curing condition: 80℃/10min+140℃/30min

5. Cleaning appliance: running water can be used

6. Avoid acid substances, or polymerization and deterioration will happen.

7. This product can be used alone,the coated surface request oil free,dust free and dry,the better make pre-treatment of degreasing,derusting,and phosphating.
