RECOMMENDED APPLICATIONS
PRODUCT FEATURES
Outstanding high-temperature stability: Effectively prevents vapor lock, ensuring reliable and safe braking even during frequent braking or intense driving;
Outstanding low-temperature fluidity: Braking response is sensitive and rapid in cold weather, reducing braking distance;
Excellent rubber compatibility: Protects the brake system's rubber seals, preventing swelling, softening or hardening, and prolonging the lifespan of the sealing components;
Good metal compatibility and chemical stability: Protects the metal components of the braking system from corrosion, maintaining stable performance over time.
