performance classification of sealant
According to the performance classification after construction
Curing sealant: This type of sealant can be divided into two categories of rigid and flexible. Rigid sealants Sulfates or hardens solids that form little after Flexible Flexible Sealants are flexible and flexible after vulcanized. Rigid sealant is characterized by not bending the seam is usually not moveable. Flexible sealant after curing to maintain flexibility.
Non-curable sealant: This type of sealant is a soft, solidified sealant that remains non-dry after being applied. The thickener continuously migrates to the surface. The glue is usually a paste that can be applied to the seam with a knife or brush to work with sealants of different viscosities and properties.
According to the purpose of use classification
1, architectural sealant: for simple wall caulking.
2, silicone weather sealant (neutral glue): for waterproof seal.
3, silicone structural sealant: for structural bonding, fixed.
4, set fire sealant: for fire seal.
5, butyl rubber: for the first insulating glass seal.
6, styrofoam: for plug sewing, and waterproof effect.
