Silicone sealant is a widely used sealing material, with excellent weather resistance, high temperature resistance, chemical corrosion resistance and good elasticity. According to different classification standards, silicone sealant can be divided into many types. This article will introduce the classification of silicone sealant in detail.
First. Classification by curing method
1. Wet curing type: wet curing silicone sealant begins to cure after contact with the moisture in the air, suitable for humid environments or occasions requiring rapid curing.
2. Thermoset type: Thermoset organic silica gel needs to be heated at a certain temperature to cure, suitable for occasions requiring high temperature curing.
Second, according to the form of use classification
1. Paste type: paste type silicone sealant is paste, suitable for applications that need to be smeared or filled.
2. Tape type: The tape type silicone sealant is in the shape of tape, easy to use, and suitable for occasions that need to be fixed quickly.
Third. Classification by chemical composition
1. Organic tin sealant: Organotin siloxane is the raw material of organotin sealant, with good weather resistance, high and low temperature resistance and chemical resistance.
2. Organotin - silicon sealant: organotin and silicon as raw materials organotin - silicon sealant, with excellent weather resistance, high and low temperature resistance and chemical resistance.
3. Organotin - rubber sealant: organotin and rubber as raw materials of organotin - rubber sealant, with good elasticity and adhesion.
Fourth. Classification by use
1. Building sealant: used for sealing doors, Windows, curtain walls and other parts of the building, with excellent weather resistance and aging resistance.
Electronic and electrical sealant: used for the sealing of electronic and electrical products, with excellent electrical insulation properties and weather resistance.
2. Automotive sealant: used for sealing of automotive engine, doors, Windows and other parts, with excellent weather resistance and chemical resistance.
3. Pipeline sealant: used for the sealing of pipeline joints, with excellent high temperature resistance and chemical resistance.
4. Other sealants: such as medical device sealants, ship sealants, etc., have special use environment and performance requirements.
In short, silicone sealant is a widely used sealing material, with a variety of classification and use areas. When selecting and using, the selection should be made according to the specific use environment and performance requirements.
