Khimtrast Primer-PM 2K — solvent-free epoxy primer
KHIMTRAST

Khimtrast Primer-PM 2K — solvent-free epoxy primer

Other waterproofing materials

This solvent-free two-component epoxy primer impregnates and strengthens concrete and other porous substrates before polyurea is applied. Mixed with quartz sand, it serves as a filler for repairing substrate defects, and under hand-applied polyurea — as a primer on metal and roofing felt. The components are mixed in a ratio of 100:40 by weight, and work is done at +15…+30 °C and air humidity max 75%; the pot life of the mix is at least 30 min, adhesion to concrete at least 2.5 MPa.

Specifications

ManufacturerKhimtrast — AO “Khimtrast”, Nizhnekamsk
Typewaterproofing material
Basetwo-component solvent-free epoxy primer: component A — a mixture of epoxy resins and functional additives (viscosity at 25 °C 350–450 mPa·s), component B — aliphatic amine (275–375 mPa·s); mix density 1,050–1,090 kg/m³
Colourcomponents — low-viscosity transparent colourless liquids
Packagingkit 1: component A — 20 l bucket of 12 kg, component B — 5 l bucket of 4.8 kg; kit 2: component A — 10 l bucket of 5 kg, component B — 3 l can or canister of 2 kg
Application methodimpregnation, strengthening and priming of concrete and porous substrates before polyurea; filler when mixed with quartz sand 0.1–0.3 mm (¼; for repairing the substrate under polyurea — 1:3 or 1:4 by weight); concrete at least M300, aged at least 28 days, moisture max 4.0 wt. %; prohibited without waterproofing and vapour barrier where there is a risk of capillary moisture; condition the components at ambient temperature, mix A:B = 100:40 by weight with a mixer at 500 rpm for 2–3 min, transfer to a clean container and mix for another 2 min; thin coat with a short-nap nylon or fur roller, rubber squeegee or spatula, a second coat if necessary; tools — acetone, Nefras, xylene, toluene
Application temperature+15…+30 °C; substrate 3 °C above the dew point; air humidity max 75% (if higher — craters and blisters)
Curingpot life at 20 °C at least 30 min; curing at 20 °C max 24 h; curing time: +15 °C — 48–72 h, +20 °C — 24–48 h, +30 °C — 12–24 h
Key propertiesadhesion to concrete at least 2.5 MPa; service temperature from −10 to +60 °C; contains no solvents; adhesion of PM Premium to wood through Primer-PM (2K) 2.15 MPa
Consumptiontheoretical 0.25–0.35 kg/m² in 1 coat; actual consumption depends on the absorbency of the substrate
Shelf life6 months from the date of manufacture; storage and transport at +5…+25 °C
StandardsTU 20.30.22-108-27903090-2022 (amend. No. 1, 2); voluntary certificate of conformity ROSS RU.32001.04IBF1.OSP28.91471, 22.12.2025–21.12.2028
