PERFORMANCES

  • Standards : FMVSS 116 DOT 4 / SAE J1703
  • Extreme thermal resistance and stability :
    • Very high boiling point (325°C / 617°F), superior to conventional DOT 5.1 non silicone base / DOT 5 silicone base fluids (260°C / 500°F mini) and DOT 4 (230°C / 446°F mini)
    • Enables effective brake even in extreme conditions.
    • Better aerodynamic performance by reducing air entrance for brake cooling on cars.
  • Efficient when rainy :
    • Very high wet boiling point (205°C / 401°F) superior to conventional DOT 5.1 non-silicone base fluid (180°C / 356°F mini) and DOT 4 (155°C / 311°F mini) enables to keep efficient braking while rainy.
    • Brake fluids tend to absorb humidity from the air, which reduce boiling point and increase the risk to get to "vapor lock" phenomena.
    • The wet boiling point is measured by humidifying the product with about 3.5 % of water.

RECOMMENDATIONS

  • Avoid mixing with polyglycols based brake fluid.
  • Do not mix with silicone (DOT 5 silicone base) or mineral base fluids (LHM).
  • Store brake fluid in its original container, tightly closed to prevent moisture absorption.
  • Aggressive chemical product if contact with hands, paint or varnish.
  • If skin contact, rinse thoroughly with water.
