3. Nature and use

JC-804 is a reactive and cross-linkable silane coupling agent that can be hydrolyzed under acidic or alkaline conditions. It is widely used in natural and synthetic rubber. It can also be used as a reinforcing agent and cross-linking accelerator for compounding. Materials (such as resin fiberglass composites), coatings, inks, glues and sealing materials, etc., can also be used as resin modification additives and enzyme fixatives.

4. Product packaging and precautions

1. Store in a sealed container, otherwise it will be hydrolyzed by moisture and form polymers.

2. It is slightly irritating to skin and eyes, so protective equipment is required when using it.

3. The finished products are packed in 5kg plastic barrels, 20kg each, sealed and stored, and are valid for one year.
