1. VOC
Volatile organic compounds (VOCs) are abundant in adhesives. The aromatic hydrocarbon solvents contained in this type of compound are highly toxic and even carcinogenic.

    2. Curing Agents and Plasticizers
Aromatic amine curing agents are extremely toxic, and some can even cause bladder cancer, such as m-phenylenediamine, etc. The plasticizer tricresyl phosphate is highly toxic, especially harmful to the liver and kidneys, and may even be carcinogenic.

      3. Toxic Fillers
There are many types of fillers used in adhesives, and some of them can also cause harm. For example, asbestos powder fibers are extremely fine, causing serious environmental pollution and being a potent carcinogen. The dust can fly with the wind, enter the human body through the respiratory tract and pores, and accumulate in the lungs, leading to lung cancer, bronchial cancer, mesothelioma, etc.

       4. Toxic and Harmful Additives
Once the base resin (or rubber) used in the adhesive is determined, the preparation and application performance of the adhesive largely depend on the regulating and modifying effects of the additives used. Attention must be paid to the toxicity of some additives. Antioxidant D has been confirmed to be carcinogenic, and MOCA, azobisisobutyronitrile (AIBN), and dibutyltin dilaurate are all highly toxic.
        Extended Information:
Methods to Prevent the Toxicity of Adhesives During Use:
1. Strengthen ventilation and exhaust in the place where the adhesive is used to avoid inhaling toxic substances through the respiratory tract.
2. Use machinery to replace manual operation when using the adhesive to avoid human contact with toxic substances. 3. When choosing an adhesive, low - toxicity or non - toxic adhesive types such as solvent - free or water - soluble adhesives can be selected.
4. When using the adhesive, masks, gas masks, gloves, and skin protectants can be used to avoid direct contact with the adhesive.
