High Purity Dacromet Coated Bolts / Corrosion Resistant Coatings Liquid
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

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.
