What are the detrimental effects of polyester resin?

Fact Checked

Polyester resin is basically the unsaturated resin that is utilizing in creating fiber-reinforced plastics and non-reinforced filled materials. It is important to note that polyester resin binds the fibers in a tight manner in order to allow loads to be transferred between fibers while at the same time providing protection from chemicals, water or harsh weather. Polyester resin is commonly used in automobile products, electronics, and gel coats in marine work and even on blades for wind turbines. There are safety regulations that must be observed since the substance can be dangerous.

Ingestion of polyester resin

If polyester resin is accidentally ingested, the first aid measure is to provide the individual with plenty of water to drink and call emergency assistance immediately. Do not induce the individual to vomit since this can cause stress on the internal organs.
