BITUMEN-POLYMERIC PRIMING "BIOM" Russian patent published in 2003 - IPC

FIELD: building materials. SUBSTANCE: invention relates to the development of bitumen-polymeric priming "Biom". Priming is designated for applying under bitumen-polymeric mastics in different constructions of combined insulting coatings based on bitumen-polymeric mastics designated for protection against corrosion, for example, steel oil and gas pipelines at temperature of their exploitation below +40 C in the following ratio of components, wt. -%: oil bitumen, 30.0-45.0; indene coumarone resin, 2.0-3.0; wool grease, 0.5-2.0; solvent, 5.0-10.0; benzine, 40.0-62.5. Invention provides the improvement of exploitation properties of protective coating, for example, oil pipelines. EFFECT: improved and valuable properties of priming. 2 tbl, 2 ex
