ZUSAMMENSETZUNG GEEIGNET ZUR BEREITSTELLUNG EINER ABRIEBFESTEN BESCHICHTUNG AUF EINEM SUBSTRAT, MIT VERBESSERTER ADHÄSION UND VERBESSERTER BESTÄNDIGKEIT GEGEN RISSBILDUNG

摘要

Compositions having improved stability which, when applied to a variety of substrates and cured, form transparent abrasion resistant coatings having improved adhesion, and improved resistance to crack formation. The coating compositions are aqueous-organic solvent mixtures containing a mixture of hydrolysis products and partial condensates of an epoxy functional silane and a disilane and a carboxylic acid component. Substrates containing the coating compositions and a process for applying the coating composite to a substrate are also disclosed.
