E-200

1 Chemical Name

1.1 Name

E-200

1.2 Molecular formula：C11H18N2

1.3Molecular weight：178.28

1.4 CAS.NO：

1.5 Molecular structure：

2、Introduction

It is liquid at room temperature with low viscosity and can be mixed, processed, measured and proportioned without heating. No specific curing procedure is required, and the surface treatment can be carried out more safely and quickly at room temperature. It can be used in epoxy resin with long activation period, wide temperature range and high temperature.

3、Physical Properties

4、solubility

It is miscible with methanol and benzene, 1.0% in water

5、Applications

E200 curing agent is an efficient curing agent and chain extender for polyurethane, polyurea elastomer and epoxy resin, especially in reaction injection molding and spraying.

6、ackage

200kg steel drum

7、storage

Easy to absorb moisture, in the presence of oxygen, will deepen the color. As with any hygroscopic compound, special care should be taken when storing or transferring. The following steps are recommended:

· store in nitrogen atmosphere. It prevents discoloration. As a benefit, dry nitrogen will displace water vapor.

Avoid high humidity and outdoor storage. After opening for use, it is better to replace the container with dry nitrogen.

Avoid long-term storage at high temperature. Higher temperatures increase the rate of darkening in the presence of oxygen.

8、Period of Vaildity：One year
