MATERIAL SPECIFICATION
SCOPE
This specification cover requirements for third rail anti-icing fluid utilized for ice and snow removal and protection from ice formation.
DEFINITION
Environmentally Friendly Third Rail Anti-Icing (PG) Smart Fluid - material produced in accordance with U.S. Patent No. 5,772,912. The smart fluid is an environmentally friendly, non-toxic, non-corrosive single-phase composition consisting of water, propylene glycol, and a synergistic exocellular poylsaccharide. The resulting homogenous smart fluid has a exceptionally high “zero” shear viscosity, which exhabits non-Newtonian psuedo plactic behavior when sheared.
REQUIREMENTS
