Basics and Applications of Silicon Sealant

Basics of Water-proof Sealant

The sealant is a kind of sealing material which will be out of shape leads with the sealing surface, it is not easy to flow, and there is certain cohesive property. It is used to fill the configuration gap, so as to play a role in the adhesive seal. It has the features of leak-proof, waterproof, anti-vibration and sound insulation, thermal insulation and other functions. Usually, it is made by using the viscous materials based on talc, clay, carbon black, titanium dioxide, and asbestos and other inert fillers, and then add to the asphalt material, natural resin or synthetic resin, natural rubber or synthetic rubber and other dry or dry plasticizers, solvents, curing agents and promoting agents. Sealant can be divided into elastic sealants, liquid packing material and sealing putty three categories. Now it is widely used in the sealing of construction, transportation, electronic instrumentation and components. Among all the applications, the window sealant is the most widely used sealant in modern construction.

Construction Sealants Supply

Building sealants is widely used for building sealing for a variety of sealing seams or holes, in order to prevent the gas, liquid, solid through to prevent structural materials to be destroyed in the structure of displacement, which plays a function of thermal insulation, sound insulation, waterproof, dustproof anti-air, fire, corrosion, shock absorption and prevent the joint accumulation of other matters. Construction sealant according to their composition classification, today there is already have polysulfide rubber, chloroprene rubber, acrylic, polyurethane, butyl rubber, silicone rubber, rubber composite, thermoplastic elastomers and others; in accordance with the construction form it is divided into type of thermal coating, cold coating type, type of curing reaction and solvent evaporation type; according to the usage, it can be divided into sealants of doors and windows with caulking, sealants for waterproof shockproof use, sealants for prefabricated walls.

Best Silicone Sealant

silicon sealant is a kind of sealing materials to seal all kinds of glass and other substrates. It can be mainly divided into two categories: silicone rubber and polyurethane (PU). And the silicone rubber is divided into acid gel and neutral adhesive, structural adhesive. And the polyurethane is divided into adhesive sub-adhesive glue and sealant. Sodium silicate is a colorless, slightly colored transparent or translucent viscous liquid in the system with water as the dispersing agent. Solid sodium silicate is colorless, slightly colored transparent or translucent glass block body. The form is divided into the three kinds of liquid, solid, water quenching, in theory, that substances is called as "colloidal". Ordinary sodium silicate is slightly light blue block or granular solid, but it is slightly colored transparent or translucent viscous liquid in high temperature and pressure dissolution .
