Abstract
Disclosed herein are coating materials and methods for applying a top-layer coating that is durable, abrasion resistant, highly transparent, hydrophobic, low-friction, moisture-sealing, anti-soiling, and self-cleaning to an existing conventional high temperature anti-reflective coating. The top coat imparts superior durability performance and new properties to the under-laying conventional high temperature anti-reflective coating without reducing the anti-reflectiveness of the coating. Methods and data for optimizing the relative thickness of the under-layer high temperature anti-reflective coating and the top-layer thickness for optimizing optical performance are also disclosed.
Claims30
A coated article, comprising:
- a substrate;
- a first coating on at least one side of the substrate;
- and
- a second coating applied on top of the first coating, wherein the second coating is formed by curing a dried film of a sol comprising a polysilsesquioxane;
- wherein the coated article has at least one of an anti-reflective property, a hydrophobic property, an oleophobic property and an abrasion resistant property.
A coated article, comprising:
- a substrate;
- a first hydrophilic coating on at least one side of the substrate;
- and
- a second coating applied on top of the first hydrophilic coating, wherein the second coating is formed by curing a dried film of a sol comprising a polysilsesquioxane;
- wherein the coated article has at least one of an anti-reflective property, a hydrophobic property, an oleophobic property and an abrasion resistant property;
- and
- wherein the reduction in absolute solar weighted transmission (TAM) after 1000 strokes of abrasion testing according to specification EN1096.2 is less than 1%.
