Epoxy resin


Epoxy resins (EP) belong to the group of synthetic resins that can be converted to a thermoset Material using a hardener. They harden without exhibiting shrinkage. Epoxy resins exhibit high mechanical load-Bearing capacity. Because they adhere well to Glass and metal, they can form composites with these materials that demonstrate excellent fatigue Strength.

Processing time (pot life) starts as soon as the hardener and resin have been mixed and varies depending on the type of resin, temperature and batch size. The viscosity of the mass can be reduced by applying heat. However, this also reduces pot life. Processing times are predominantly short and can be further shortened by adding accelerators.

To prevent quality problems and ensure no residues of the reaction partners are left after curing, it is usually important to make sure the hardener and resin are mixed in a stochiometric ratio. If there is too much of the hardener, the mass will become brittle. If there is too much of the resin, the end products will be too soft.

Epoxy resins are used as Casting and laminating resins and to produce components designed to cope with high electrical and mechanical loading.
