1. Introduction of products
Fire-retardant Silicone Sealant is a one-component neutral silicone sealing product with fire-proof and smoke-proof functions. It is designed for flame-retardant requirements and is widely used in indoor and outdoor construction and home decoration, as well as for bonding and sealing of joints. It has a wide range of applications, excellent aging resistance, is not affected by extreme temperatures, and is flame-retardant, crack-resistant, shrinkage-resistant, stretch-resistant, aging-resistant, and water-resistant.
2.Product advantages
(1)Excellent flame retardant performance, reaching the highest flame retardant level of FV-0.
(2)Excellent tensile and compressive recovery.
(3) Neutral curing, non-corrosive to building materials such as metal, coated glass, concrete, marble, granite, etc., and widely used.
(4) Excellent weathering resistance and high and low temperature resistance.
(5)It has excellent adhesion, and after curing, it forms a strong seal with most building materials and does not require the use of primer.

4.Usage and Precautions
(1) )Single component, usage method has good extrusion and thixotropy in the range of 4~40℃, and can be directly applied by squeezing with a glue gun.
(2) It cannot be used as a structural sealant;
(3) It should not be used on all materials that exude grease, plasticizers or solvents, such as the surface of oiled wood;
(4) It should not be used in airtight and unventilated places; it should not be used on frosted or wet surfaces;
(5) It should not be used when the surface temperature of the material is lower than 4℃ or higher than 50℃;
