As the name implies, high temperature resistant epoxy vinyl ester resin will have higher temperature resistance than commonly used resin products, and it is also an internationally recognized highly corrosion resistant resin. In terms of product type, it can be divided into the following two categories.
Category one, bisphenol A epoxy vinyl ester resin
Product features: Compared with HS-4451 resin, HS-4457 is more suitable for the production of FRP products. It is widely used in chemical engineering and industry of many chemical media such as acids, alkalis, salts, organic solvents, etc. It is an ideal high-temperature type FRP heavy anti-corrosion resin.
Gel time (min): 10.0-30.0
Heat distortion temperature: 150
Category II, phenolic epoxy vinyl ester resin
Product features: Compared with the general type bisphenol A epoxy vinyl ester resin, it can maintain high mechanical strength at high temperature, and has a broad spectrum of acid, alkali, salt, organic solvent, oxidizing medium performance, especially for Long-term tolerance in acidic oxidizing environment. It is suitable for various glass fiber reinforced plastic molding processes such as hand lay-up, winding, pultrusion, etc. It is an ideal high-temperature glass fiber reinforced plastic anti-corrosion resin.
Gel time (min): 17.0-28.0
Heat distortion temperature: 145
In the above, we introduced two types of high temperature resistant epoxy vinyl ester resins, and explained their viscosity, gel time and heat distortion temperature. I believe that under this introduction, everyone will know more about this product. If you need high temperature resistant epoxy vinyl ester resin, please contact us in time.
