Abstract

Ultra-thin alkali free glass with high breakdown strength was coated with submicron polyurethane coating. The polymer coating heals surface and edge defects and improves the bending properties such that the minimum bending radius was ∼1 cm. The dielectric permittivity and loss of the polymer coated glass was ∼6.4 and <0.01 respectively up to 125 °C and was similar to the uncoated glass. The process allows to mitigate the effect of edge defects caused due to the cutting or handling of glass and is key to the development of high temperature wound glass capacitors.
