What are the harmful substances in industrial coating supplies?

The harmful substances in industrial coatings mainly include the following categories:
Volatile Organic Compounds (VOCs)
Organic solvents such as benzene, toluene, and xylene may cause respiratory irritation or damage to the blood system after volatilization.  ‌
Benzene derivatives
Long term exposure to substances such as benzene, toluene, xylene, etc. may lead to dizziness, anemia, and even leukemia.  ‌
heavy metal
Common heavy metals include lead, cadmium, chromium, mercury, etc. Long term exposure may damage the nervous system or cause chronic poisoning.  ‌
Isocyanates
TDI, HDI and other components in curing agents may cause asthma or allergic reactions.  ‌
Paint mist particles
The paint mist particles generated by spraying may cause pneumoconiosis or respiratory irritation.  ‌
Noise and high temperature
The noise generated by spray gun operations may damage hearing, and the high temperature environment during the baking process may cause heatstroke.  ‌
Preservatives and additives
Some coatings contain ester compounds or other additives, and excessive exposure may cause discomfort such as headaches and nausea.  ‌
Standard limitations: According to standards such as GB 30981-2020, industrial coatings must strictly control indicators such as VOCs, benzene derivatives, heavy metals, etc., for example:
Benzene content ≤ 0.3% (solvent based coatings)
Lead content ≤ 1000mg/kg (water-based coating)
