The product is based on propylene glycol and hence gives a very safe level of toxicity when compared to ethylene glycol based anti-freezes. The RXSOL PRO COOL 50/50 formulation includes 50% distilled water to give zero lime scale deposits, optimum frost protection in severe winter conditions, plus excellent anti-corrosion performance.

The balanced inhibitor system incorporated in FUCHS SILKOLENE RXSOL PRO COOL 50/50 is the result of several years research and development and is designed to protect the cooling system against foaming, scale formation and corrosion. Anti-cavitation performance exceeds that of conventional ethylene glycol based antifreezes,providing the user with superior protection against engine and coolant pump damage due to this phenomenon.
