Resin epoxy Usage And Synthesis

Description

Resin based on epichlorohydrin and bis phenol A. Oligomers may vary in molecular weight from 340 and higher. May produce erythema multiforme like eruptions. The higher the molecular weight, the less sensitizing the compound.

Chemical Properties

Resin epoxy is white to straw slab

Uses

Resin epoxy is Surface coatings, as on household appliances and gas storage vessels; adhesive for composites and for metals, glass, and ceramics; casting metalforming tools and dies; encapsulation of electrical parts; filament-wound pipe and pressure vessels; floor surf

Uses

Epoxy resin is used in adhesives, surface coatings, electrical insulation, plasticizers, polymer stabilizers, laminates, surface coatings, paints and inks, product finishers, PVC products, vinyl gloves, etc.; in the building industry, electron microscopy, and sculpture.

Preparation

Epoxy resin is prepared by the following condensation reaction:

The condensation leaves epoxy end groups that are then reacted in a separate step with nucleophilic compounds (alcohols, acids, or amines). For use as an adhesive, the epoxy resin and the curing resin (usually an aliphatic polyamine) are packaged separately and mixed together immediately before use.
Epoxy novolac resins are produced by glycidation of the low-molecular-weight reaction products of phenol (or cresol) with formaldehyde. Highly cross-linked systems are formed that have superior performance at elevated temperatures.

Definition

Resin epoxy is a thermosetting resin based on the reactivity of the epoxide group. One type is made from epichlorohydrin and bisphenol A. Aliphatic polyols such as glycerol may be used instead of the aromatic bisphenol A. Molecules of this type have glycidyl ether struc

Hazard

Strong skin irritant in uncured state.

Solubility in organics

Acetone, benzene, MEK, THF, toluene, xylene
