Applications

Epoxy-amine system

Epoxy-amine system

Epoxy-amine,phenol formaldehyde resin, dicyandiamine system etc., high or middle curing temperature

Epoxy-dicyandiamine, phenol formaldehyde resin system etc.

Applications:

102A can react with aliphatic amines and aromatic amines at normal temperature and with hydroxy compound nylon, etc. at high temperature, It is mainly used in epoxy coating and adhesive .Epoxy-polyurethane interpenetrating polymer network or sea-island structure is formed after curing, which can improve the flexibility of material, enhance the shear strength, adhesive force, tensile strength and bending strength of adhesive layer. At the mean time its effect on the heat resistance of composite materials is relatively small. It can also be cured directly with amines such as aliphatic amine and aromatic amine at normal or middle temperature, thus obtaining elastic body with good performance.

102B can react with aliphatic amine, aromatic amine, hydroxy compound, nylon, etc. at high or middle temperature. It’s mainly used in epoxy coating and adhesive. Epoxy resin( phenol formaldehyde resin, polyester) -polyurethane interpenetrating polymer network or sea-island structure is formed after curing, which can improve the flexibility of material, enhance the shear strength, adhesive force, tensile strength and bending strength of adhesive layer. At the mean time its effect on the heat resistance of composite materials is relatively small. It can also be cured directly with amines such as aliphatic amine and aromatic amine at normal or middle temperature, thus obtaining elastic body with good performance.

Usage:

The amount as toughener is 10-30% of the weight epoxy resin, meanwhile the amount of curing agent should be enlarged. The amount as elastic gum is 300% of the weight of epoxy resin.

The products can be added to epoxy resin or amine curing agents.When102A-1,102A-2, 102B-1 added to amine curing agents, the mixture can be used after 7 days at normal temperature or 4hrs at60. When 102B-2 added to amine curing agents,the mixture can be used after 4 hrs at80.

Package:

2kg/bar.,20kg/bar.,210kg/bar.

Storage:

Keep in a tightly closed container. Strictly forbidden moisture from getting in. Storage life: 12 months under25.
