Ice Barrier®

Power Line Anti-icing/Deicing Agent

Formulated with renewable raw materials, Ice Barrier’s® aliphatic alcohol properties disrupt the freezing crystalline structure of moisture droplets, weakening them so they will not form ice crystals or create a solid bond to metal surfaces. Ice Barrier not only enables transit commissions to meet regulatory and operational obligations, but also gets the job done in a manner more protective to the environment than other products on the market.

Don’t Let Severe Winter Weather Delay Your Transit Vehicles

Midwest’s Ice Barrier utilizes NASA “smart fluid” technology to keep ice at bay on overhead catenary systems, allowing transit vehicles reliant on power lines to keep moving, even in the worst winter weather. Ice buildup on these power lines can cause expensive problems in two primary ways. First, even a small amount of excess weight from ice formation can cause lines to exceed their load limit designs. This can result in extra stresses to hangars and connectors and can drop lines from their mount.

Second, ice interferes with power transmission between the line and the contact shoe. This can stop a transit vehicle in its tracks. These problems result in expensive repairs and maintenance as well as costly delays (from ticket reimbursements or freight penalties). They are also labor-intensive to resolve.

Ice Barrier is the companion product to Midwest’s Zero Gravity Third Rail anti-icing agent, which also uses NASA’s Zero Gravity “smart fluid” to protect third rails from ice and snow buildup. Like its companion, Ice Barrier works as an anti-icing agent, preventing ice formation by disrupting the freezing structure of water molecules, thereby lowering the freezing point. This keeps moisture from forming ice crystals or solid bonds to treated surfaces.

Ice Barrier works very efficiently, only requiring a thin film on wires. While it sprays on as a liquid, the “smart fluid” ingredient allows it to become highly viscous, forming a gel-like layer on wires that resists being washed away and that forms a barrier between moisture and the surface of the wire.

Ice Barrier Features and Benefits

Keep Power Lines Up and Operational in the Harshest Weather

While Ice Barrier works to keep your transit vehicles moving, it does so in the most environmentally-friendly way possible. It is made up of renewable materials, unlike glycol-based products (made from hydrocarbons). And it is biodegradable and non-corrosive.

Ice Barrier keeps your transit lines moving with the following features:

  • Keeps power lines from exceeding their load limits, which can cause them to drop from their mounts
  • Prevents ice from blocking power transmission from wires to the transit vehicle’s contact shoe
  • Effective below -40º F
  • Is alcohol-based instead of glycol-based, meaning it uses renewable instead of hydrocarbon-based raw materials
  • Uses Zero Gravity “smart fluid” licensed from NASA, making it resistant to being washed off wires by rain, snow or sleet
  • Can be sprayed as a liquid (lower viscosity) but then solidifies into a gel (high viscosity) to remain in place on wires
  • Biodegradable
  • Requires no recirculation or agitation
  • Non-flammable, non-corrosive, non-conductive
  • Minimum 2-year shelf life for product stability and effectiveness
