& Two-component polysulfide building sealant has a delicate and uniform paste appearance. It is a substance or viscous body, so it is also usually called two-component polysulfide building sealant. Two-component polysulfide sealant and two-component polysulfide sealing paste are the same product.
The two-component polysulfide sealing paste uses liquid polysulfide rubber as the main base material, adds a variety of chemical additives, and is made through a special polymer material synthesis process. It is a two-component seal that can self-vulcanize and cross-link at room temperature. Glue has good adhesion to metal, concrete and other materials. It can maintain good air tightness and waterproofness under continuous expansion, vibration and temperature changes. It can maintain good air tightness under continuous expansion, vibration and temperature changes. It is waterproof, oil-resistant, solvent-resistant and has excellent durability. There are two types of two-component polysulfide sealant (non-sag type, self-leveling type). The first is a non-sagging two-component polysulfide sealant, which is suitable for deformation joints in various cement buildings. It is applicable regardless of whether the deformation joints of the building are standing joints, ground joints, or top joints. This sulfur seal is coated After being applied to the vertical joints or roof joints of the building, the sealant will not flow and fall from the construction joints, but will stick directly to it. Therefore, the non-sag two-component polysulfide sealant is particularly It is suitable for the construction of standing joints or roof joints in buildings; the second type is a self-leveling two-component polysulfide sealant, which looks like a watery liquid glue, like water, and can flow in deformation joints. It is only suitable for The ground joints used in the deformation joints of cement buildings are fluid. After mixing them in proportion, they can be poured directly into the ground joints and they can flow into the deformation joints of the building. When constructing the ground joints of the building plane, use Self-leveling two-component sealant will save time and effort.
Application fields:
Two-component polysulfide building sealant (glue) is suitable for waterproofing metal and concrete curtain wall joints, underground projects (such as tunnels, culverts), reservoirs, cisterns and other structures. Sealing, as well as expansion sealing of expansion joints on highways, runways, etc., repair and restoration of cracks in buildings, especially suitable for joints of water plant net distribution pools, sealing between filter plates, and expansion joints of sewage pools in large sewage treatment plants Waterproof sealing of deformation joints in various liquid storage structures such as sealing.
Features:
Two-component polysulfide building sealant is a product with very stable waterproof performance. It is based on liquid polysulfide rubber with groups at the end of the molecule and bonds in the molecular chain. A two-component sealing material that uses metal peroxide as a curing agent. After the two components are mixed in a given ratio, they are cured at high temperature to form a rubber-like elastomer. It is widely used in civil construction projects as a waterproof sealing material. Its characteristics are as follows:
It has good weather resistance and durability, and will not produce cracks after long-term use;
It has sufficient stable adhesion and durable adhesion to the sealed components, and has long-term adhesion to concrete in water. Adhesion
The water vapor transmission rate is extremely low, and the two-component polysulfide sealing paste has very good waterproof function
It is not eroded by fungi and has excellent resistance to fungi
It has good construction workability, and the two-component polysulfide sealant can be well filled into the joints
It has excellent resistance to fuel, hydraulic oil, water and various chemicals;
For sealing components No pollution, no corrosion, two-component polysulfide sealant is harmless to the human body.
&Construction method:
The building must be kept dry, clean, and free of oil
According to the design requirements, fill the joints with backing material;
The bottom should be removed before construction Apply the coating liquid to the surface. After the surface is dry, stick wide protective tapes on both sides of the gap to prevent excess polysulfide glue from contaminating the surface of the structure during construction. Place the barrel of white polysulfide glue (assembly) in the box. Part) and the bag of black curing agent (Component B), stir thoroughly until there is no color difference;
Fill the mixed polysulfide sealant (non-sag type) into the gap with a putty knife or glue gun. Fill it completely, and then use a &c wide putty knife to smooth the glue; the flat-flow type can be poured directly into the ground cracks;
After applying the glue, remove the protective tape. Avoid exposure to water and rain within hours;< br/>
