Epoxy Resin

1. Main applications:

Widely used in adhering, pouring, resisting corrosion, painting of petrochemical, electric, electronic, machinery, architecture, vehicle, food, automobile, aviation fields.
It is often regarded as all-purpose adhesive.

2. Properties:

Epoxy resins are divided into fluids and solids, and low molecular weight of epoxy resins are fluids, high molecular weight of epoxy resins are solids.
Epoxy resins have excellent processing technical, adhering, electric insulating, chemical-medicine-resistance, dimension-stable properties.
The products are high mechanical strength, low water absoption, low thermal expansivity, low shrinkage rate.

3. How to use:

It is necessary to remove oil, rusty, lacquer and dirty on the workpieces which will be used, then mix epoxy resin curing agent and relative auxilaries uniformly in definite proportions, finally the work pieces can be used.

4. Package, storage and transportation:

Liquid epoxy resins re packed in iron drums, and the solids epoxy resins are packed in plastic bags.
Stored in dry, colds and well ventilated warehouse.Its shelf life is one year, beyond this time, it can still be used if it is qualified after retesting.
Transportation as non-hazardous chemicals.

Bisphenol-A Epoxy Resins

1. Properties:

The resins are linear thermal-plastic stuff before curing, and become hardened into unsolvable and unfusible cross-linked network after being cured.
Excellent processing property and good adhesion to most of the matrixes;
Low shrinkage and good dimension maintenance;
Excellent chemical stability and electric insulation property;
High mechanical strength and good anticorrosion.

2. Applications:

E-44, E-42 (floatable under room temperature):
Used as adhesive to various metals and nonmetals such as glass, wood, ceramics, cement, textile, and most of thermal setting plastics (phenolic plastic, alkyd plastic, etc);
Used as dipping and encapsulating materials of electric and electronic components, as well as adhesives and coatings of light-conductive materials and optical instruments.
E-20, E-12(solid at room temperature)
Mainly used as anticorrosive coatings, insulation coatings and electrophoresis coatings, etc.
Widely used in aviation, shipping, chemical equipment manufacture as sealing, waterproof, damp-proof, antiriot, heat-resistant, cold-resistant, impact-proof and shock-proof materials, etc.

4. Storage and tansportation:

Storage: In dry, cold, and well ventilated storehouse; keep away from sunlight, fire and heat source.
Shelf time: 1 year.Beyond the time, it still can be used after being tested and qualified.
Transportation: As non-hazardous chemicals.

Phenolic Epoxy Resins E-44

1. Structure specialities and properties:

Possesses much more crosslinking joints and much denser network after being cured compared with bisphenol A epoxy resins as in every single molecular there are more than two epoxy groups.
Good entire rigidity after being cured;
Good mechanical properties;
Excellent electric insulation property;
High viscosity as its high molecular weight.

2. Applications:

Used in laminates and glass fiber reinforced products;
Used as encapsulating materials for electronic components;
Used in making arc-resistant, heat-resistant and insulation finished products.

1. Molecular Formulary:

NH2C2H4NHC2H4NHCH2CHOHCH2OC4H9

2. Properties and Applications:

---As modified aliphatic amine, the agent possesses more activated hydrogen and ether bond in its structure, which can make epoxy resin cured at room temperature;
---The curing reaction with epoxy is slow and gentle, that makes the processing easy to handle;
---Little harm to human health as its high boiling point, low vapor pressure, and low concentration in air;
---An ideal curing agent for the epoxy products which need to be solidified at room temperature;
---Recommended mixing proportion: 593#/Epoxy =23-25/100
---Besides, several similar products such as 703A, T31, CHT-251 have parallel or better properties and applications.

1. Chemical Structure:

omitted

2. Properties and Applications:

---The 501 is able to join epoxy resin curing reaction as there is a epoxy group in its molecular structure, so that there is no possibility for the 501 to escape from cured epoxy products, and can make cured epoxy resin tougher;
---Can make epoxy resins thinner before curing as its low viscosity, so that can improve the flow ability of epoxy resin as well as its infusion and dipping properties;
---Joined with 501, more fillers could be added into epoxy resin, thus its shrinkage and production cost could be lowed down;
---Also, this diluent could be used in solventless paint.
---Widely used as diluents of epoxy resins, sealing, pouring, dipping, laminating, adhering, resisting corrosion, stable agent, finishing agent of fiber, etc.
