What harm does powder coating have to the person's body

Most powder coating powders use resins with very little toxicity, and the curing agent is significantly more toxic than the resin. However, when the two are prepared into powder coating powders, the toxicity becomes very small, or almost non-toxic.

The animal test showed that the instant inhalation of powder coating powder, no death and injury symptoms, but the eyes and skin have different degrees of irritation.

Although the general powder coating powder has no obvious harm to the human body, it will also bring some irritation and allergic phenomenon after it is attached to the skin, eyes and respiratory tract.


Many years of production practice has shown that isocyanate triglycidyl vinegar (TGIC) has obvious skin irritation and variation of the protomaterial under humid conditions.

According to European studies, TGIC is confirmed to be a toxic substance, and the dangerous goods mark is shown on the logo of the product. The dosage of TGIC in powder coating powder has been greatly reduced, and a considerable part of it has been replaced by curing agent such as hydroxylalkyl amide amine.

In our country, we also gradually realize TGIC toxicity problems, promote the use of non-toxic hydroxyalkyl acylating agent, and its usage is also growing, but prepared with this curing agent powder coating powder on the heat resistance properties of still exist certain problems. People accept more slowly, believe that the future national attention to the environmental protection work, this will speed up the pace.

The harm of powder coating powder to the human body is quite big. Why does the country not stop the production of powder coating powder? Because now all industries are inseparable from this powder coating powder.

Although powder coating powder has no obvious toxicity, inhalation of human trachea and lungs is still harmful to the human body if excessive inhalation will also cause silicosis (formerly known as silicosis), so in the production and coating of powder coating powder, attention should be paid to the following problems:
(1) In powder coating powder production and painting workshop, construction sites are often kept clean, to prevent equipment dust leakage and dust flying workshop, to have good ventilation; ​in the equipment and parts that are easy to produce dust, negative pressure conditions should be caused. It is better to install special dust removal devices, and turn on the dust removal equipment when necessary.

② In order to prevent the powder coating powder from adhering to the skin and inhaling into the respiratory tract, wear protective gloves, work cap, work clothes and dust mask during working hours.

③ After the end of each production task, timely blow off the dust adsorbed on the body, and timely wash off the dust on the face and hands.

(4) In conditional units, employees must wash their face, hair, bath and change work clothes after work to avoid bringing dust out of the workshop and causing unnecessary pollution.
