Aluminum coupon, dipcoated in ISurGuard on its lower half only (brown), after a freezing rain event. Its coated portion was entirely ice-free.

A section of aluminum-wrapped electrical transmission line (ETL) was spray-coated with superhydrophobic (SHPb) ISurGuard on both ends, leaving a center area bare. It was hung outdoors in below-freezing Minnesota winter weather overnight, then ice water was poured over it. On close inspection, it is evident that water penetrated the bare uncoated portion and froze into it, encasing it thickly in ice. The ISurGuard-coated portions prevented water penetration and the icicles are only loosely attached and originate where water beaded up in the grooves on the top of the transmission wire. There is significantly less weight of ice on the ISurGuard-coated portion of the ETL, helping to prevent breakage and power outages during storms.

ISurGuard coatings repel snow from covering fabric (here, a nylon satellite dish cover): the right half is coated, that to the left is not. There is no snow on the coated portion of the fabric cover.

ISurGuard repels dirt and rainwater from fabric (here, black ripstop nylon): the left piece is coated, the one to the right is not; both were mounted outdoors throughout a Minnesota summer and pictured after a rain event.

ISurGuard repels mud from fabric: the right half is coated, the left half is not; both were pressed into a dish of wet mud (see videos in ISurGuard in Action).

ISurGuard coatings keep water off metals, protecting them from corrosion.

Two coupons of aluminum were immersed in red water-based dye for one year. The ISurGuard coated coupon on the left shows little corrosion, while the uncoated aluminum coupon is severely corroded after one year.
