Product Overview

Olean Chemical Epoxy Resin D.E.R 331 is a versatile liquid epoxy resin for a wide range of applications.

Product Characteristics

• Composition and Appearance: Generated by the reaction of epichlorohydrin and bisphenol A, it is a colorless or light yellow transparent liquid with bright color, which is advantageous in some applications where color is required.
• Epoxy Value and Equivalent: Epoxy equivalent is 182 – 192g/eq, epoxy percentage is 22.4 – 23.6%, epoxy group content is 5200 – 5500mmol/kg, the higher epoxy value makes it reactive and reacts well with a variety of curing agents.
• Viscosity: at 25℃, the viscosity is 11000-14000mPa・s, moderate viscosity makes it has good fluidity, easy to operate and mix with other substances.
• Other indexes: the content of hydrolyzable chlorine is not more than 500ppm, the content of water is not more than 700ppm, the density is 1.16g/ml at 25℃, the content of epichlorohydrin is not more than 5ppm.
• Good adhesion properties: excellent bonding strength to a wide range of materials such as metals, ceramics, glass, plastics, etc., which can be used to manufacture high-performance adhesives.
• Excellent physical properties: good mechanical properties after curing, including high hardness, strength and toughness, can withstand a certain amount of pressure and impact; at the same time, it has excellent electrical insulation properties, suitable for electrical and electronic field of insulation materials.
• Strong chemical stability: it is stable to alkali and most solvents after curing, has good chemical resistance, and can maintain stable performance in different chemical environments.
• Good heat resistance: undiluted low molecular weight standard liquid epoxy resin, the highest temperature resistance up to 204 ℃, can be used in a certain high temperature environment.

Product Applications

• Coating field: Used in automotive coatings, can coatings, coil coatings, marine and industrial anticorrosive coatings, light-curing industrial coatings, etc. It can provide good corrosion resistance, abrasion resistance and decorative properties.
• Composites: Combined with glass fiber, carbon fiber and other reinforcing materials, it creates high-performance composites for aerospace, automotive, marine and other applications to improve the strength and durability of the structure.
• Electronic encapsulation: Used for potting and encapsulation of electronic components to protect them from the external environment and improve the reliability and stability of electronic equipment.
• Other fields: also used in adhesives, casting and molds, civil engineering and other fields, such as the manufacture of high-strength structural adhesives, for concrete repair and reinforcement.。
