Innolayn NC40 RF3 — R4 grout for work at −25…−10 °C
Cementitious R4 grout for installing equipment, columns, joints and anchors at sub-zero temperatures; 15 MPa after 6 hours at −25 °C.

The anti-corrosion Profskrin LC2.5 performs two tasks: it protects reinforcement against corrosion and creates a bonding layer on the substrate. The grey compound, based on Portland cement with mineral filler and 0.63 mm aggregate, provides bond to the substrate of at least 2.0 MPa and flexural strength from 8 MPa at 28 days. Until it hardens it is protected from water; the material works at pH from 5 to 14 and temperatures from −60 to +80 °C.
