Silane Coupling Agent Storage & Handling Guide


1. Care is required in storage of silane coupling agents to avoid denaturation by the reaction with water or moisture.

2. Once the container is opened, replace the stopper tightly as soon as possible to prevent intrusion of moisture.

3. The storage room must be dark and cool. High temperature and high humidity are absolutely undesirable for storage of silane coupling agents.


Silane coupling agents are subject to hydrolysis when in contact with water. Hydrolysis of a Silane Coupling Agent is accompanied by the formation of hydrogen chloride, methyl alcohol, ethyl alcohol, aklyl ethers of ethyleneglycol and other hydrolysis products so that carefulness is essential in handling and using silane coupling agents.

1. Silane coupling agents must be kept away from fire and moisture and should not be kept standing in an open condition as far as possible.

2. Work rooms for handling silane coupling agents should be well ventilated. Avoid inhalation of the vapor and contact with the vapor.

3. Skin and eyes must be protected from silane coupling agents by use of protective glove and eyeglasses. If silane coupling agents get on the skin or in the eye immediately wash in running water. Subsequent consultation with a doctor is recommended.

4. Care should be taken not to put a Silane Coupling Agent on clothes. Clothes which come in contact with silane coupling agents should be immediately washed in running water.

5. Workers are recommended to thoroughly wash their hands after handling a Silane Coupling Agent, particularly, before eating, drinking or smoking.

6. Split Silane Coupling Agent must be removed by washing away with a large volume of water or absorbed by rags or sand followed by disposal by burning.

7. In particular, Chlorosilanes have a sharp, disagreeable odor. This odor is an early warning signal, even at very low concentrations. Chlorosilanes are flammable. Chloro Silane Coupling Agent decomposes when in contact with atmospheric moisture to produce corrosive hydrogen chloride gas. Further, it strongly irritates the skin so that sufficient care is essential in handling.
