Silicone Sealant Environmental Requirements for Use of Construction.Due to the curing method of silicone sealant for construction, the following usage restrictions must be observed when using it:

Not suitable for the surface of building materials that seeps out grease, plasticizers or other solvents;

Not suitable for frosted or wet surfaces, airtight or long-term soaking occasions;

Not suitable for paint surfaces, seal failure may occur due to cracking or peeling of the paint film;

Not suitable for surfaces that are in direct contact with food or are subject to mechanical wear;

It is not suitable for construction at noon or when the surface temperature of building materials is lower than 4°C or higher than 40°C;

Non-structural adhesives are prohibited for structural assembly.

Various glues have their own relative usage restrictions such as:

Acid glue: Corrosion to copper, brass and other metals, not suitable for all kinds of stone and iron carbide matrix materials;

De-alcohol glue: It is not suitable for direct construction at noon or in the sun, and should not be used in fluorocarbon materials;

Loss of adhesive: There are traces of corrosion to metals such as copper, brass, and silver, and should not be used in the mirror industry.
