The main reason for producing odor in the production of acid adhesive is that during the production process, methyl triacetoxysilane reacts with 107 adhesive and releases a large amount of acetic acid. So when using acidic crosslinking agents, workers must use labor protective equipment, such as protective glasses, masks, and gloves. The acidic crosslinking agent itself is non-toxic, mainly irritating to the skin and respiratory mucosa. Do a good job of protection and it will not cause any harm to the human body.
