Dacromet Corrosion Resistant Coatinguid for High Strength Fasteners

Corrosion Resistant Coatings Feature

1 Hydrogen-free hydrogen embrittlement is the traditional galvanizing process can not completely overcome the shortcomings.
As the process characteristics determine the Dacromet in the course of treatment without any acid treatment, there is no plating during the hydrogen leakage problem, coupled with the coating at high temperature curing, so from the process to ensure that the Dacromet coating will not There is hydrogen embrittlement. This makes it possible to apply anti-corrosion treatment to high-strength parts with high tensile strength requirements.

2 pollution-free and pollution as a "green plating" process, Dacromet process using a closed-loop approach, in the pre-treatment: in addition to the oil and dust with a special equipment collection and treatment; in the coating, curing, There is no traditional electroplating process in the process of acid, alkali, chromium and other heavy metal sewage problems, resulting only from the coating evaporated from the water vapor, the determination, does not contain the provisions of the state control of harmful substances.

3 soft appearance, can be further painted Dacromet coating was matte silver gray, can be re-painted on top. This, to meet the requirements of the appearance of high quality requirements of the workpiece, such as bicycles on the fasteners, baskets, etc., in the coating Dacromet coating, the need for a layer of paint The

Corrosion Resistant Coatings​ Technical data

Coating Process

Attentions

Other chemicals such as any kinds of acid, alkali salt can not be mixed into coating, for these can activate Zn & Al plate to aging the coating.

Avoid irradiation of sunshine and ultraviolet ray for long time when operating, otherwise it will accelerate aging or polymerization of the coating .

It is very important to control the temperature of coating. If the temperature of coating changes when operating, it will effect the viscosity, then effec the coating quatity on workpiece. So the relations among temperature,viscosity and spinning process shoud be controlled well when coating.

The viscosity will be different if coating method is different. Choose low data if spray coating,and choose high data if dip spin coating.

Packing

Quality guarantee period

Before compound 6 months at 20℃

After compound 40 days at 20℃ ( It can be recycled if adding fresh coating continuously. )

It should be stored under 20℃ if not in use.
