Surface roughness reduction using spray-coated hydrogen silsesquioxane reflow

- Spray-coated silsesquioxane coating can be applied to planar and non-planar surfaces.
- Cured coating sustains in excess of 10,000 molding cycles.
- The peak-to-valley roughness is decreased 10 to 20 times.
- Good agreement between mechanical (AFM) and optical (VSI) methods.
