Description
Bituminous polymer polymeric Albizol (BP) – produced at the Kostroma waterproofing materials plant, is an improved and more inexpensive modification of the bituminous polymer sealant Technonikol (higher adhesion, higher softening point, more UV stabilizers). It is used to seal expansion joints, to rehabilitate temperature and strength cracks in cement concrete, asphalt and concrete and polymer-concrete coatings of roads, bridges, aerodromes (there is an experience of Albizol application both at civil airfields and military ones)
The variants of sealant production differ in the temperature of flexibility on the bar, in which there are no cracks in the sealant (that is, the degree of modification), BP-G25 is suitable for warm climatic zones where the winter temperature is not lower than -20 degrees, BP-G35 is suitable for central Russia , where the minimum winter temperature is at least -30 degrees. BP-G50 was developed specifically for the northern regions of the country, this modification of the sealant withstands negative temperatures down to -50 degrees.
