Features of the composition and use of sealants
By the common concept of “sealants”, scientists mean compositions created around complex polymers as polysulfide or watery silica -organic rubber. Standard sealants are usually used for the maximum filling of multi -sized cracks in the concrete surface, a dense layer of plaster built by a brick wall or, for example, a wooden plate, hermetic sealing of window seams and various joints, reliable fixation of glasses in installed window frames.
The choice of such popular material as sealants usually directly depends on the material of a particular surface, the maximum permissible possibility of deformation of the seam, as well as on a certain degree of resistance to all kinds of chemical, temperature and other external factors, for example, atmospheric pressure.
In their unique internal structure, the obtained materials specializing exclusively in sealing the seams or, in another way, sealants, in fact, are a very thick shapeless and outwardly pasty mass that can polymerize as much as possible with a complete evaporation of any liquid solvent.
Depending on the preferred method of using such material, sealants are divided into widespread silicone sealants, relatively popular acrylic sealants for wood, plus polyurethane sealants and rarely encountered thiocol sealants. These varieties usually differ from each other in color, a certain level of viscosity of the material, as well as individually designed operational indicators.
