In the precise operation of an engine, coolant plays a key role in maintaining the optimal working temperature. However, an often overlooked yet highly damaging problem, foam, is quietly eroding the efficiency and lifespan of the cooling system. High-speed circulation, high temperature and pressure, and interactions among additives easily lead to foam growth. These stubborn foams not only reduce the heat transfer efficiency of the coolant and cause localized overheating, but also accelerate water pump cavitation, causing component damage and even metal surface corrosion due to the "cavitation" phenomenon, planting hidden dangers for engine safety.
Facing this industry pain point directly, Chemi Tech, through in-depth research and development, has launched a highly targeted series of defoamers for engine coolant. The core of our solution lies in precisely breaking down the foam's stable structure. The product uses specially designed composite defoaming substances that can quickly penetrate the foam liquid film, reduce its surface tension, prompt the foam to burst instantly and suppress the generation of new foam. Its excellent compatibility ensures stable synergy with various glycol-based or propylene glycol-based coolants as well as common preservatives and corrosion inhibitors, keeping the cooling system clean and efficient over the long term.
Achieving efficient defoaming requires following clear steps. The first step is diagnosis and evaluation, analyzing the specific composition of the coolant system and the main causes of foaming. The second step is model matching; the Chemi Tech technical team will recommend the most suitable defoamer model based on the diagnosis results. The third step is addition and verification; at the recommended addition ratio (usually very low, 0.01%-0.1%), evenly mix the defoamer into the coolant base fluid or concentrate and conduct a foam tendency test under simulated working conditions to ensure the defoaming speed and durability meet the standard. The whole process is efficient and convenient without changing the existing production process.
An auto parts manufacturer encountered a severe foam challenge in developing a dedicated coolant for its new-generation high-power engine, with serious foam overflow in high-temperature endurance tests. After introducing Chemi Tech's customized defoamer solution, the coolant's foam volume under 120 degrees Celsius high-speed shear conditions was immediately reduced by more than 90%, and it maintained a very low foam tendency throughout the entire 500-hour long-duration test. This not only solved the testing bottleneck but also significantly improved the reliability and market competitiveness of the final product, earning the customer's full recognition.
Choosing Chemi Tech means injecting steady protection into your engine cooling system. Let us dispel the fog of foam together and safeguard the powerful heartbeat of every engine.
