==Hardcoat Composition Comprising Methyl or Ethyl Trialkoxy Silane, Articles and Methods - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18026268 titled 'Hardcoat Composition Comprising Methyl or Ethyl Trialkoxy Silane, Articles and Methods

==Simplified Explanation==

- The patent application describes articles that have a substrate and a hardcoat layer on top of it.
- The hardcoat layer is made up of a reaction product of a composition that includes hydrophobic silane monomers.
- Optional second silane monomers can also be included in the hardcoat layer.
- The hardcoat layer may contain silica nanoparticles in a certain weight percentage.
- A hydrophilic silane surface layer can be added on top of the hardcoat layer.
- The patent application also includes a method for using articles with a rewritable surface, as well as methods for making the hardcoat compositions and articles.


==Original Abstract Submitted==

Articles are described comprising a substrate and a hardcoat layer disposed on the substrate. The hardcoat layer comprises the hydrolyzed and condensed reaction product of a composition comprising: i) first hydrophobic silane monomer(s) having the formula RSi(OR)wherein R and Ris methyl or ethyl; ii) optional second silane monomer(s) having the formula (R)Si(OR)or Si(OR), wherein R, Rand Rare organic groups with the proviso that Ris not methyl or ethyl and m ranges from 1 to 3. The hardcoat layer N may further comprises 10 to 30 wt. % silica nanoparticles. A surface layer comprising a hydrophilic silane may be disposed on the hardcoat layer. Also described is a method of using an article having a rewritable surface, hardcoat coating compositions, and methods of making hardcoat compositions and articles.
