Grease for bituminous masses

Vegatol Bentox 2 grease is a specialized lubricant for use in the road and asphalt industry.

Vegatol Bentox 2 grease is a high-quality, specialized plastic grease resistant to temperatures up to 200°C, designed for the harshest operating conditions found in equipment used for the production and installation of mineral-asphalt mixtures. Its unique formula was developed with consideration for the high temperatures, aggressive chemical environments, and the presence of dust and solid particles typical of asphalt pavers and asphalt mixing plants (commonly known as paving plants).

Bentox 2 is a response to the growing requirements for reliability, durability and lubrication efficiency in the most demanding mechanical systems.

General characteristics of the grease

• Grease type : Mineral oil based grease with bentonite
• Consistency class according to NLGI : 2
• Thickener : Bentonite (inorganic thickener)
• Color : Light brown
• Structure : Homogeneous, smooth paste
• Operating temperature : from –20°C to +180°C (short-term up to +200°C)
• Dropping point : none (characteristics of bentonite grease)

 

Application

Vegatol Bentox 2 is designed specifically for extreme operating conditions where traditional lithium or calcium greases fail. It is primarily used in:

1. Bituminous pavers

lubrication of rolling and sliding bearings,

chains, guides and joints working in direct contact with hot bituminous mass,

lubrication points exposed to contact with dust, water and high temperatures.

2. Bituminous mass production plants (mixing plants)

transport systems (belt conveyors, bucket conveyors),

drum and planetary mixers,

rotating elements exposed to overheating and dust,

bearings of drying and heating drums.

Advantages and functional properties

1. Resistance to high temperatures

Thanks to the use of bentonite as a thickener, Bentox 2 grease maintains its structural stability even at temperatures up to 200°C, making it an ideal choice for bitumen applications with operating temperatures exceeding 160°C. Unlike traditional lithium greases, it does not tend to liquefy or leak from lubrication points.

2. Excellent adhesion to the surface

The grease exhibits high adhesion to metal, allowing it to adhere to surfaces even under strong vibrations, heavy loads, and in the presence of hot bituminous vapors. It protects components from direct contact with external factors, reducing wear and corrosion.

3. Extremely high resistance to water washout

Bentox 2 is practically not washed out by water (both cold and hot), which is particularly important in outdoor applications – when working in rain, mud, snow or when washing equipment under pressure.

4. Chemical resistance

The grease is resistant to most chemicals found in the working environment of asphalt pavers, including asphalt vapors, organic acids and de-icing agents.

5. Long-term anti-corrosion protection

The anti-corrosion and antioxidant additives contained in the grease ensure long-term protection against corrosion even in the event of periodic lack of relubrication.

6. Pointless nature of melting

Thanks to the use of bentonite, the grease does not have a classic dropping point - it does not liquefy under the influence of high temperatures, but retains its paste structure, which eliminates the risk of leakage and loss of lubricating properties in highly loaded nodes.

Benefits of using Vegatol Bentox 2 grease

Using grease Vegatol Bentox 2 in bitumen production and spreading equipment translates directly into:

• Reduction in lubrication frequency – thanks to better grease retention and durability,
• Extending the life of bearings, guides and joints – by reducing friction and protecting against overheating,
• Increasing the reliability of the machinery park – especially in the summer season, where lubrication failures can paralyze the operation of an entire section of road works,
• Reduction in lubricant consumption over the season – which translates into real savings in operating costs.

Operating recommendations

• Store at temperatures between +5°C and +40°C , in original, tightly closed packaging.
• Do not mix with other types of greases , especially lithium or calcium greases – negative reactions leading to loss of viscosity or change in consistency are possible.
• The relubrication period should be determined individually depending on the operating conditions and intensity of the device use – for typical use, it is recommended to check every 7–10 days.
• Manual application or through central lubrication systems – Bentox 2 has good pumpability in pressure systems.

 

Summary

Vegatol Bentox 2 grease is a top-class product that meets the specific requirements of the road and asphalt industry.
