In the FRP industry, we are familiar with the smell of resin. For example, the smell of 191 resin is styrene. Some people joke that it's a little strange not to smell in a day. The joke belongs to the joke, but it is necessary to protect it as well as possible. No money to earn, but only one life, long-term inhalation harm is no less than chronic drug use.
You can baidu science popularization, styrene is in the list of class 2B carcinogens, like most vinyl and unsaturated resin adhesives, the proportion of styrene solvent is as high as 30%. When the unsaturated resin hardens, it will release a lot of toxic fumes. The long-term harm of inhalation is not clear. In fact, a sentence can cause cancer should be enough, said many are tears! Don't be bothered or the boss won't pay for it. Wear an activated carbon mask yourself! Try to minimize the harm, the body is your own, slowly realize it!
