New silicone coating suits engineering applications

The elastomer is claimed to retain elasticity at very low temperatures (down to -140ºC) as well as resisting breakdown at elevated temperatures up to 300ºC.
R-2183 can be sprayed, knife coated, or spin cast to create a coating with a tear strength of 175 30.9 kN/m, a tensile strength of 10.7 MPa, and an elongation of 800%.
The material is optically clear, says NuSil, suiting it for use as an encapsulant. It can also be heat-cured into a thin elastomeric film.
The material is formulated as a two-part addition-cure silicone dispersion with a 1:1 mix ratio for ease of use.
