| Hazard Information | Back Directory | [Characteristics]
Phenolic epoxy resin is a kind of phenolic resins modified at the phenolic hydroxyl group to include an epoxide functional group (usually a –CH2-(C2H3O) group, where -(C2H3O) is the three-membered epoxide ring). The added functionality of the phenolic resin increases the ability for the resin to crosslink, creating a stronger polymer with high resistivities.
| [Uses]
Molding compounds; surface coatings;
adhesives; laminating or reinforcing plastics | [Application]
Phenolic epoxy resin is often used as coatings or resistive top coats for drums, pipes, floors, tanks and automotive parts. The high chemical and solvent resistivities and temperature compatibility of it is most useful in high-performance applications and corrosion resistance.
| [Health Hazard]
The toxicity of epoxy resin
systems results from the toxicity of the various
components, each of which must be
considered. | [Materials Uses]
Phenolic polymers are widely used for fire-resistant applications but suffer from high porosity and low fracture toughness, limiting their structural performance. To address these challenges, researchers propose a catalyst-free approach to crosslink phenolic with epoxy, forming hybrid polymers with denser networks, reduced porosity, and enhanced thermal–mechanical properties. The findings demonstrate the potential of Phenolic epoxy resin for high-temperature, fire resistant applications requiring robust structural integrity and low porosity[1]. | [References]
