What are the common fiberglass resin adhesives?
Thread Content
The processing of fiberglass-reinforced plastic material can be simply summarized as one layer of glass fiber followed by one layer of adhesive, and then another layer of glass fiber followed by another layer of adhesive. I want to know what models of fiberglass adhesive are commonly used? I heard from a technician that their factory uses X2; maybe I heard that wrong. I have visited a fiberglass processing plant before, and there was a very strong, pungent odor there, which came from the adhesives used. I wonder what effects working in such an air environment for a long time could have on one’s health?
The binder for fiberglass is resin. It can be divided into types such as epoxy resin, phenolic resin, furan resin, and unsaturated polyester resin, among which unsaturated polyester resin is widely used. When the poster smells a pungent odor, it is the smell emitted by the crosslinking agents in the resin (usually styrene), which can affect the respiratory tract. At present, what fiberglass factories can generally do is provide workers with masks and improve ventilation.
Resins can be classified into types such as epoxy resins, phenolic resins, furan resins, and unsaturated polyester resins. Unsaturated polyester resin is widely used.
Fiberglass reinforced plastic is a composite plastic whose matrix is resin and whose reinforcing material is glass fiber. Resins come in many types; they can be roughly classified as vinyl resins, such as S901 and A410, epoxy resins, such as D470, and unsaturated resins, such as P61, SW963, and P199
The introduction on the second floor is passable. The smell in fiberglass factories is toxic; working there for long periods can cause problems. **There are relevant standards and safety regulations, but how many companies actually comply with them?** They all make profits at the expense of workers’ lives.
Yes, during the curing process of resin, styrene is released. Styrene has a pungent odor. What the worker mentioned should not be ×2; it should be -2 (read as: bar two), which is a type of vinyl ester resin.
The odor is toxic, but the impact of glass fibers on the lungs cannot be ignored either.
