Coldex calcium sulfonate grease is a product that has the ability to carry much more load by exceeding the standards. At the same time, it offers long-term working performance due to its ability to work in wide temperature ranges. In this way, it maintains its superior performance by maintaining its form at very low and very high temperatures.
Excellent durability under extreme loads.
Provides superior protection against rust and corrosion.
The cost is much lower because the lubrication period is long-lasting. Calcium sulfonate greases are commonly used in automotive, agriculture, construction, mining, paper production, iron and steel mills and the food industry. Specific automotive applications include chassis, ball joints, universal joints and wheel bearings. Industrial applications include continuous casters, conveyors, ball mills, crushers, offshore and underwater applications.
Calcium sulfonate greases are also used in motorized steam valves to control high pressure steam. These steam valves are typically found in nuclear power plants and thermal manufacturing stations. It is also known that the calcite particles found in calcium sulfonate greases make them a good choice for high temperature applications.
Calcium sulfonate greases are generally beneficial in rust-inhibiting performance and oxidation stability is considered good or excellent. Rust inhibitors are surfactants that neutralize acids on the metal surface. They can also form an oily surface or barrier to stop rust on the surface.
Maden Sektörü Ağır Hizmet Rulman Gres, yüksek basınçlı buharı kontrol etmek için motorla çalışan buhar valflerinde de kullanılır. Bu buhar vanaları tipik olarak nükleer santrallerde ve termal üretim istasyonlarında bulunur.
Maden Sektörü Ağır Hizmet Rulman Gresleri genellikle pas performansı için faydalıdır ve oksidasyon kararlılığı iyi veya mükemmel kabul edilir. Pas önleyiciler, metal yüzeyindeki asitleri nötralize eden yüzey aktif maddelerdir. Yüzeydeki pası durdurmak için yağlı bir yüzey veya bariyer de olabilirler.
-20 / 185 °C Wide operating temperature range.
Sulfonate grease is resistant to water and chemicals.
Resistant to oxidation and long-lasting.
Its pumpability is very high.
It has very good retention properties. 
In rods with vibrating and impact loads in the iron and steel industry
Lubrication of high temperature bearings, plain bearings and turrets
