Dewatering Polymer Chemistry Is:
- High elasticity.
- The absence of cracks.
- The exception of delamination.
- Application on a wet surface.
- Work upon the old coatings and rust.
- Filling of capillaries.
- Memory effect.
- History of creation and range of applications.
Multigrades Dewatering Polymer Compositions «Pokrol» are an improved modification of modern polymer-bitumen materials. These compositions have an improved microstructure and include several high-tech supplements and additives in their compounding. Dewatering Polymer materials are widely used for the protection of building materials and constructions against moisture and salt solutions, as well as for anticorrosion treatment of sea and river ships, vehicles and to protect bridges and mooring facilities.
Dewatering Polymer Compositions are applied equally well both on dry and clean or wet and dirty surfaces. For this reason, they are especially effective when used on large objects, exposed to constant moisture and salt fogs and in the cases where before treatment drying is difficult or impossible.
As it known, at the micro level bitumen-polymer materials are the mixture of oxidized bitumen and SBS (styrene-butadiene-styrene) rubber or an equivalent polymer, molecules of which looks like a thin threadlike structures. The main task of the synthesis of such materials is the necessity to deploy rubber molecules of tangles in the threads and to fix them in such condition. Conventionally, this problem is solved by mixing the heated components for some period of time.
Formation of the elastic stressed protective layer.
After the evaporation of the solvent and polymerization, Dewatering Polymer Compositions forms highly elastic protective film on the materials surface. This film is always a bit stretched as it consists of many times interwoven elastic threadlike polymeric molecules. Therefore, the protective coating does not flake off, even if the
material was applied to poorly prepared surface with fragments of an old paint or corrosion.
In fact, a metal construction is placed in an elastic bag, tightly stretched and glued to the surface.
