Modern dual-clutch transmissions (DCTs) change gears very quickly and are much more fuel-efficient, but they are very complex. Wear on the gears, clutch slippage, and friction variations may result in poor performance and costly failures. Transmission issues not only reduce vehicle reliability but also increase maintenance costs and diminish customer satisfaction.
Chempol 4690, designed by Chempol, is designed to meet these challenges. As a high-performance DCT additive, it maximizes friction management and gear protection, and aids smooth gear changes. It is a suitable product due to its high formulation level, which offers thermal stability, oxidation resistance, and compatibility with hydraulic systems, and can therefore be used in automotive and industrial applications.
The addition of CHEMPOL 4690 to transmission fluid formulations will enable manufacturers and lubricant formulators to significantly extend transmission life, enhance efficiency, and minimize the risk of clutch or gear failure.

The DCT additive is a special chemical component that enhances the performance of dual-clutch transmission fluids. It is specifically designed to meet the requirements of modern dual-clutch applications, especially wet multiplate clutches and synchronizers, unlike traditional transmission additives.
DCT additives are important for maintaining a consistent level of friction in the clutch, reducing gear wear and ensuring smooth synchronizer operation. Dual-clutch system lubrication ensures transmission efficiency is at its peak and slippage is reduced, which is vital for both high-performance and everyday cars.
Here are some of the common challenges in modern transmissions:
The engagement of high-speed gears generates significant frictional heat. Lack of thermal stability causes transmission fluids to oxidize, leading to decreased efficiency and faster component wear.
Clutch friction variations may lead to rough shifts and poor wet multiplate clutch operation. Lack of consistent friction not only makes driving uncomfortable, but also reduces the life of gears and synchronizers.
Constant gear and clutch movement may result in abrasion, pitting, and premature wear when the transmission fluid lacks the necessary wear performance. Smooth operation and friction life is necessary both in OEM and aftermarket applications.

CHEMPOL 4690 is a high-quality package of DCT fluids that can address the problems of the modern transmission systems. Its new formulation combines the best in modern transmission lubrication technology, offering a dependable solution to automotive and industrial applications.
The additive provides the best clutch friction optimization, smooth gear shifting, effective gears and synchronizers protection. Its high-performance composition provides thermal stability, oxidation resistance and superior copper corrosion protection that is why it is a good selection to use as automotive lubricants additives.

Here are some of the key features of Chempol 4690:
CHEMPOL 4690 also offers a constant level of friction in wet multiplate clutches, preventing slip and allowing a smoother gear engagement process. This also minimizes wear on clutches and synchronizers.
The additive creates a protective coating on gears surfaces, reducing the mechanical stress and abrasion. The improved synchronizer performance will provide accurate and dependable gear shifts in all operating conditions.
The advanced formulation strikes a balance between friction and lubrication and allows smooth and effective gear transitioning. There is also reduced jerking or lag during shifts for drivers, enhancing the performance of the transmission.
The operation of high-speed transmission generates heat that may cause degradation of the normal fluids. CHEMPOL 4690 is better oxidation resistant and thermally stable, maintains the integrity of the fluid and increases service times.
The additive prevents corrosion in sensitive parts of transmission especially copper and brass parts, and prolongs the life of internal parts.
CHEMPOL 4690 is compatible with hydraulic systems in cold climates without allowing sluggish performance, and it has a smooth clutch engagement, resulting in an efficient transmission.
Here is how Chempol 4690 improves transmission performance:
CHEMPOL 4690 prevents slippage by controlling clutch friction and lessens wear, which ensures components last longer.
The formulation of the additive preserves the fluid viscosity and flow properties of the additive, which enables the hydraulic system to operate accurately and efficiently even during different temperatures.
The better friction control gives smoother gear engagement in synchronizers, producing less noise, less wear and mechanical stress on transmission parts.
The thermal stability, resistance to oxidation and gear protection are a combination that guarantees the transmission last longer, saving on maintenance cost and making the automotive gearbox to be more efficient.

Below are the different applications of this additive in various industries:
CHEMPOL 4690 allows formulators to create high performance transmission fluids that can be used on modern vehicles and give them long term durability and performance.
OEMs can use CHEMPOL 4690 in their transmission designs to ensure smooth shifting, optimum clutch engagement, and long life.
The additive suits sports and hybrid cars, as well as commercial cars, which have high levels of friction control, thermal stability and dual clutch system lubrication to achieve maximum efficiency.
