Cryotech Polar Guard® II — Type II aircraft de-icing fluid

Cryotech Polar Guard® II is a Type II aircraft de-icing fluid designed to provide both de-icing and short-term anti-icing protection. With a thickened, gel-like consistency, it clings to aircraft surfaces, helping prevent reformation of ice and snow during ground operations in moderate winter conditions.

Key benefits

Enhanced holdover time

Provides longer protection against re-icing compared to Type I fluids

Improved cling & coverage

Thickened formula ensures better surface adherence, even on inclined aircraft components

Operational efficiency

Reduces the need for reapplication in moderate weather conditions, helping streamline pre-takeoff procedures

Fully certified

Compliant with FAA, EASA, and ISO 11075 standards

Bio-based MPG option available

Eco-conscious formulation available with renewable bio-based mono-propylene glycol for reduced impact

Industry Application
Formulated using mono-propylene glycol (MPG) and advanced thickening agents, Polar Guard® II delivers high performance, extended holdover time, and full compliance with international aviation safety standards.
