Description
Viscogen KL: Synthetic High-Temperature Chain Lubricant
Description
Castrol Viscogen™ KL range are thermally stable synthetic lubricants designed for high-temperature lubrication in severe environments, where the use of mineral oils or conventional synthetic oils would result in excessive wear, carbonisation, and residue formation. They can be used up to temperatures of +240°C (+464°F), depending on the viscosity. Developed from base fluids, Viscogen KL forms exceptionally adherent, transparent, and odourless lubricating films. Its additive system is free of solids, metals, or silicone, which enhances load-carrying capability and wear protection.
Application
Viscogen KL is available in six different viscosities depending on the ambient and operating conditions. When selecting the right viscosity, consider the dimensions and structural shape of the chain (e.g., roller, pin, ladder chains, insertion and flat link hoisting chains). The method of application must also be considered, including manual lubrication, drip feed lubricator, central lubrication, sump lubrication, or spray can application.
Common industrial applications include:
- Highrack storage shelves
- Bakery machines
- Paint lines
- Conveyor chains
- Tenter frames and dryers
- Washing plants
- Underfloor chains
- Steamers
- Slashers
- Baking ovens
- Slide ways
- Spindles
- Ropes
- Open gear wheels
- Plastic toothed belts
- Sheet-fed offset machines
Viscogen KL 23 is especially suitable for use in BOPP (Biaxially Oriented Polypropylene) film stretching machines.
Advantages
Viscogen KL offers several advantages compared to conventional chain oils:
- Low Evaporation Rate: Low residue formation and smoke generation at high temperatures reduce maintenance and lubricant consumption while providing a better working environment.
- High Load Carrying Ability: Performs well under severe mechanical loads and high temperatures, with excellent penetration on chains and wire rope strands, leading to longer chain life.
- No Dripping: Prevents dripping or throwing off at high speeds or high temperatures, reducing lubricant consumption.
- Excellent Rust Protection: Extraordinary oxidation resistance and no hard carbon build-up lead to longer chain life and reduced maintenance.
