Waterproofing measures: Can be applied even in flowing water conditions (after leakage, during water flow)! Non-hardening waterproof putty, suitable for hand holes/cable and pipe penetrations for various types of leaks.

Tometaro is a non-curing, polyolefin-based waterproofing putty for leak prevention and repair. It adheres firmly to resins, rubber, metals, and concrete, making it a versatile waterproofing material that can also be applied in flowing water conditions. It is suitable for leak prevention in electrical equipment handholes and at penetration points for cables and pipelines. It is resistant to salt, acid, and alkali, and because it does not cure after opening, it can be stored for long periods as long as it is within storage regulations. ◎ Issued in June 2020: "Guidelines for Flood Prevention Measures for Electrical Equipment in Buildings" ◎ <Features> ■ Heat resistance up to 90°C, stable waterproofing without yielding to high-pressure cables ■ Putty alone/waterproof performance clears 0.05 MPa (with optional use, 0.15 MPa) ■ Can be used even during leaks (flowing water) ■ Consideration for cable re-pulling allows for removal and re-filling ■ Unlike curing waterproofing materials, it has no curing shrinkage and can continuously seal ■ Provides peace of mind with a wealth of adoption records in both public and private sectors ■ Safe rodent prevention, blocking rodent intrusion ■ A wide range of options to accommodate various situations ■ "Japan Quality" ensures reliable and trustworthy quality ■ Ecology & Safety, gentle on the earth and humanity *For more details, please request a catalog by Email or download the PDF data from the "IPROS site"。
