NuSil Technology Expands Line of Ice-Phobic Silicone Coatings

Four durable, eco-friendly elastomers join family of laboratory-tested ice-phobic materials

The industry called for a wide range of ice-phobic coatings, including fuel resistance and toughness, and we have responded to the demand by supplementing our line with these four coatings.

NuSil Technology (, a cutting-edge manufacturer of silicone-based materials for aerospace, aircraft, electronics and photonics industries, completed extensive ice adhesion testing and broadened its line of ice-phobic coatings by adding four new products — all room temperature vulcanizing (RTV), one-part cure systems consisting of both fluorosilicone and polydimethylsiloxane (PDMS) coatings.

Ice build-up can cause major safety concerns, serious problems across many industries, and subsequently great economic impact. Ice-phobic coatings are commonly used on aircraft wings, control surfaces, and engines. They are also designed for use on marine vessels, wind turbines, surface vehicles, lock walls, hydroelectric intakes, and communication and power lines.

Current solutions, such as heating systems and chemical de-icing, can be costly and must be used after each exposure, offering only short-term protection. In addition, chemical de-icing is hazardous to the environment and some chemicals have even been banned. The EPA recently increased airport restrictions regarding how much glycol, a hazardous chemical commonly sprayed on aircraft to remove ice, must be captured in order to reduce exposure to the environment. NuSil’s line of ice-phobic materials offers a more durable, environmentally friendly alternative that provides long-term protection.

In a recent study, the ice adhesion strengths of ice-phobic coatings were tested and compared using a method developed to measure the bond strength of ice to a substrate. In order to evaluate the effectiveness of these types of materials, the Department of the Army, Engineer Research and Development Center, Cold Regions Research and Engineering Laboratory (CRREL) in Hanover, NH, U.S., utilizes a Zero-Degree Cone test to measure the adhesion strength of ice to surfaces. The results showed that several of NuSil’s ice-phobic materials, most notably R-3975 and R-1082, outperform the industry standard Teflon®.

Two of the new additions are R-3975 and R-3930 — one-part, fluorosilicone, RTV silicone elastomers for coating, sealing and bonding applications requiring solvent and fuel resistance against fuels such as JP8 and DiEGME. NuSil’s R-3975 maintains resiliency over a wide operating temperature range.

In addition, R-1009 and R-1082 are similar one-part, RTV silicone elastomers for use in ice-phobic applications not requiring fuel or solvent resistance, offering two different cure chemistries: oxime and acetoxy. While R-1009 exhibits slightly better ice-phobic characteristics, R-1082 has more robust physical properties.

“R-3975 and R-1082 together with the R-3930 and R-1009 are powerful additions to supplement our existing R-2180 heat-curing ice-phobic silicone coating,” said Brian Nash, VP of Sales & Marketing. “The industry called for a wide range of ice-phobic coatings, including fuel resistance and toughness, and we have responded to the demand by supplementing our line with these four coatings.”
