FS-S Structural sealant

FS-S Structural sealant

FS-S is a silicone structural sealant specially designed for building glass curtain wall with good adhesive properties.

Product advantages:

  • Single component, neutral curing;

  • Easy to use, good extrusion performance;

  • Rapid curing at room temperature, non-toxic, non-corrosive;

  • Excellent resistance to UV, water, high and low temperature;

  • Excellent adhesion, good compatibility with other neutral silicone adhesives .

Installation Instructions:

  • Clean the surface of the material to be bonded, squeeze the glue from the barrel to the interface with a glue gun, and trim the glue before it has cured;

  • The width and thickness of silicone structural sealant should not be less than 6mm;

  • The width of silicone structural sealant must be greater than or equal to its thickness;

  • The interface of the ketone structure sealant must be able to be filled with the standard standard construction method. 

Limitations :

  • Not suitable for all materials that will ooze grease, plasticizers or solvents, such as the surface of oil-impregnated wood; 

  • Not suitable for frosted or wet surfaces; 

  • Not suitable for continuous flooding or wet conditions throughout the year.
