Frequently Asked Questions
We offer engine coolant solutions in three categories: Ready-to-Use (RTU) coolants, coolant concentrates, and coolant additive packages, allowing customers to choose finished products or formulation solutions based on their business model.
RTU coolants are pre-mixed 50/50 products ready for immediate use. Concentrates are 100% coolants intended for local dilution, private labeling, or customized market applications.
Additive packages are formulation solutions designed for producing coolant concentrates or ready-to-use coolants. They provide a complete inhibitor system without the need for in-house formulation development.
When formulated and applied according to recommended practices, our products are designed to meet major international standards such as ASTM, SAE, JIS, GB, and GJB, depending on the product type and application.
Yes. Our OAT products are primarily designed for light-duty applications, while our low-silicate products can be formulated to meet heavy-duty engine requirements when supplemented as required.
Our coolants are generally compatible with conventional and organic coolant technologies. However, system flushing is recommended when changing coolant types to ensure optimal performance.
Yes. Customized solutions are available to support specific application requirements, target standards, or regional regulatory needs, supported by professional technical expertise.
Typical service life ranges from 3 to 10 years, depending on product type, formulation, operating conditions, and maintenance practices.
