Bisphenol A Type Epoxy E51 Quality Standards.

Bisphenol A Type Epoxy E51, also known as BPA Epoxy E51

or Bisphenol A Diglycidyl Ether, is an epoxy resin commonly

used in various industrial applications like coatings,

adhesives, and composites. It is essential to adhere to

specific quality standards to ensure the resin's

performance and safety. These quality standards encompass

various parameters, including appearance, viscosity, epoxy

equivalent weight, and purity.

1. Appearance:

The appearance of Bisphenol A Type Epoxy E51 should be

a clear, colorless to pale yellow liquid or solid at room

temperature. It should be free from any suspended particles,

sediments, or impurities.

2. Viscosity:

Viscosity is a crucial property that indicates the

flowability of the resin. The viscosity of Bisphenol A Type

Epoxy E51 is typically measured at 25°C using a Brookfield

viscometer. The acceptable range of viscosity may vary

depending on the specific application and desired

properties of the cured resin.

3. Epoxy Equivalent Weight (EEW):

Epoxy equivalent weight (EEW) is a measure of the

average molecular weight of the epoxy resin. It represents

the weight of resin containing one equivalent weight of

epoxy groups. The EEW of Bisphenol A Type Epoxy E51 is

typically specified within a certain range to ensure

consistent reactivity and performance.

4. Purity:

The purity of Bisphenol A Type Epoxy E51 refers to the
