FIELD: construction.
SUBSTANCE: primer contains a bitumen-polymer mastic, a surfactant neonol AF 9-10, a dissolvent nefras A-130/150. The component ratio is as follows, wt %: bitumen-polymer mastic - 25-30; surfactant neonol AF 9-10 - 1.0-2.0, nefras - A-130/150 - 68-74. The bitumen-polymer mastic contains the following components, wt %: oil bitumen BND 60/90 - from 85 to 95; elastomers: EDPM - 40, 60, DSSR 2525 - from 1.5 to 5; a thermoplastic elastomer DST 30R-01 - from 2.0 to 4.5; a plasticiser - sulphurised tall oil of HTM, LTM brand - from 1.0 to 4.0; and a corrosion inhibitor - polyethylene amine - from 0.2 to 3.5.
EFFECT: bitumen-polymer primer is highly resistant to cathode flaking and has improved operational properties.
