Technosynthese® mechanical transmission lubricant. This product is specifically designed for mechanical transmissions, synchromesh or unsynchronized gearboxes, differentials / gearboxes, gearboxes and hypoid differentials without limited slip system subject to jerks, heavy loads and low revs or moderate loads and high revs . Thanks to its formula reinforced with a synthetic base, this extreme pressure lubricant offers effective anti-wear protection for greater resistance to high temperatures and greater durability. This product offers a high lubricating power that reduces friction and wear, and also has anti-corrosion and anti-foaming properties. This high temperature viscosity grade (SAE 90) provides excellent oil film strength and / or reduces transmission noise. Its high fluidity at low temperatures makes it easy to change gears when mechanical parts are cold. Therefore, it is not necessary to force the gear lever to change gears. Suitable for joints of all kinds and yellow materials used in gearboxes.
