A composition suitable for the provision of an abrasion-resistant coating on a substrate, with improved adhesion and an improved resistance to cracking

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.
