Resin is a liquid.It is mixed with several chemical materials to form Fiberglass. Fiberglass is not a metal. It is a hard plastic. Fiberglass has the advantages of corrosion resistance. It is mainly used to store alkaline acid substances. Of course, chemicals are harmful to the human body. However, it is just that resin is not harmful to the human body. Another problem is that when installing “Fiberglass” components, it is necessary to polish. The polished Fiberglass dust is extremely harmful to the human body !!
I hope that workers must wear gas masks when operating !!
