PROTAK-500

Highly adhesive grease designed for use in wet environments

Formats disponibles :

Description

PROTAK-500 is a heavily additized grease offering exceptional adhesion to

metal surfaces. It is specifically formulated to withstand very high loads, absorb intense

shock and vibration, and resist extreme moisture conditions.

Thanks to its physico-chemical properties, it is ideal for the marine sector as well as

for lubricating pins and bushings (plain bearings) on heavy mobile equipment.

Features and Benefits

Using advanced overbased calcium sulfonate thickener technology, PROTAK-500 adheres to metal surfaces without dripping, even under extreme humidity or high-temperature conditions. It helps reduce grease consumption by 20 to 25% compared to conventional lithium greases, while providing significantly superior protection against wear and corrosion.

Applications

PROTAK-500 is ideal for lubricating marine equipment, construction machinery, heavy-duty truck chassis, as well as facilities in the following sectors:

steel and aluminum production, mining operations, amusement parks, and the pulp and paper industry.

Directions for Use

Use PROTAK-500 in accordance with the equipment manufacturer’s instructions.
