4 usages of silicones for coating agents

Use 1  Silicone based ResinsUsed as the resin itself

Silicone Resins
Silicone Resins
Structure:
Resin having a high molecular weight and three-dimensional siloxane network structure.
Features:
With excellent film-forming abilities, coatings can range from very hard to flexible.
Silicone Oligomers (Type A)
Silicone Oligomers (Type A)
Structure:
Resin having a relatively low molecular weight and three-dimensional siloxane network structure. Molecules contain alkoxy groups and non-reactive functional groups.
Features:
Can be used on their own, or to modify organic resins. Can also be used as reactive diluents.
Features

Use 2  Resin Hybridization AgentsUsed to improve other resins and impart them with the properties of silicones

Silane Coupling Agents
Silane Coupling Agents
Structure:
Monomer whose molecules contain alkoxy groups and reactive functional groups.
Features:
While alkoxy groups improve adhesion to inorganic materials, reactive functional groups improve adhesion to organic materials.
Silicone Oligomers
Silicone Oligomers
Structure:
Oligomer having three-dimensional siloxane network structure. Molecules contain alkoxy groups and reactive functional groups.
Features:
Can also be used for modification of organic resins, or even as a reactive diluent.
Silicone Resins
Silicone Resins
Structure:
Resin having a high molecular weight and three-dimensional siloxane network structure.
Features:
With excellent film-forming abilities, coatings can range from very hard to flexible.
Modified Silicone Fluids
Modified Silicone Fluids
Structure:
Two-dimensional siloxane main chain with reactive or non-reactive functional groups in the side chains and ends.
Features:
Silicone fluids having reactive functional groups can be used for modification of organic resins.
