Epoxy Resin E51 Composite Material Adhesive Coating Field

Product Introduction

Basic Information: E51 epoxy resin is a liquid bisphenol A type epoxy resin, produced by the reaction of bisphenol A and epichlorohydrin.

Product Characteristics

• Chemical Composition: E51 is a bisphenol A type epoxy resin with high epoxy equivalent and good chemical stability.

• Performance Features:

• High Bonding Strength: Excellent bonding performance to various materials (such as metal, wood, glass, etc.).

• Good Mechanical Properties: The cured resin has high strength and good toughness.

• Chemical Corrosion Resistance: Good tolerance to chemical media such as acids, alkalis, and salts.

• Electrical Insulation: After curing, it exhibits good electrical insulation properties, suitable for the electronic and electrical fields.

• Curing Method: Typically requires the use of a curing agent (such as amines, anhydrides), with various curing conditions, curing can occur at room temperature or under heating.

Application Fields

• Coatings: Anti-corrosion coatings, floor coatings, etc. Can be made into solvent-free coatings, with bright colors, good peel resistance, and convenient construction.

• Adhesives: Used for structural adhesives, electronic encapsulating adhesives, etc. Suitable for bonding tiles, concrete, granite, wood, aluminum plates, marble, etc., can be used in damp environments, and also for reinforcing cracks in reinforced concrete.

• Composite Materials: As a matrix resin, combined with reinforcing materials such as glass fiber, carbon fiber, to manufacture composite materials.

• Electrical Insulation Materials: Encapsulation and insulation of electronic components. Used for insulation in electrical and electronic fields, such as good workability of castables, good fluidity, high mechanical strength, and good insulation performance.

Viscosity (40℃): ≤2500 mPa·s.

Performance Characteristics

Strong Adhesion: The polar hydroxyl and ether groups in the molecular chain give it high adhesion to various substances, with low shrinkage during curing and low internal stress, helping to improve adhesion strength.

Low Shrinkage: The reaction with the curing agent proceeds through direct addition or epoxy ring-opening polymerization, without releasing volatile by-products, curing shrinkage is less than 2%.

Excellent Mechanical Properties: After curing, it has good mechanical properties.

Outstanding Electrical Performance: It is an excellent insulating material with high dielectric properties, resistance to surface leakage, and arc resistance.

Good Chemical Stability: After curing, it usually has excellent resistance to alkalis, acids, and solvents. By selecting appropriate resins and curing agents, special chemical stability can be achieved.
