What are the ingredients of silicone sealant?
The main ingredient of silicone sealant is polydimethylsiloxane, which is a silicone polymer, usually represented by poly(dimethylsiloxane). In addition, it also contains the following auxiliary materials:
Cross-linking agent: helps the sealant to cure and form a network structure.
Filler: Increase the hardness and durability of the sealant.
Plasticizer: Adjust the fluidity and applicable environment of the sealant.
Coupling agent: Enhances the adhesion of the sealant to other materials.
Catalyst: Promotes the curing process of the sealant.
These ingredients work together to make silicone sealants have excellent chemical resistance, environmental resistance and high temperature resistance, suitable for a variety of construction and industrial applications.
