Mainly composed of high-purity Sodium polyacrylate (≥99%), organic polymers, dispersants, tackifiers, and penetrants.
The Natorgrease LG 2 is a high-performance, high-quality lithium-based grease that meets industry standards. Formulated with refined mineral oil and special additives, it offers outstanding wear resistance, extreme pressure performance, exceptional adhesion, excellent chemical stability, and superior rust and corrosion resistance. It is particularly suitable for lubricating bearings or gears under heavy loads or impact conditions.
Natorseal TAW 3Q is a tail sealant for shielded tunnel boring machines. It effectively seals together with wire brushes the gap between the shield tail and the concrete segments to prevent the ingress of water or soil. It is formulated to resist high water and ground pressures, flame retardant and has excellent pumping properties and adhesion to all surfaces.
