[Problem Solving Case] Radiator Cap Component (Negative Pressure Valve)

Introducing fluororesin coating for harsh operating environments where coolant fluid comes into direct contact!

We would like to introduce a case where we solved a problem by applying a fluororesin coating to the radiator cap component (negative pressure valve), which provided non-adhesive properties. The coolant liquid previously used, which contained a non-amine-based rust inhibitor, had issues such as damaging the main pressure valve (rubber) and causing the negative pressure valve (SUS) to seize. This led to the coolant liquid being unable to move between the reserve tank and the radiator during low temperatures, resulting in overheating and causing damage or rupture to the radiator. After hearing about these issues from the customer, our company selected the coating. We utilized the non-adhesive properties of the fluororesin to prevent the fixation of the main pressure valve and the negative pressure valve. 【Improvement Effects】 ■ The coating no longer peels off ■ Prevented seizing *For more details, please refer to the PDF document or feel free to contact us.
