Abstract
Waterborne suspensions include surface treated silica particles, a water dispersable binder resin, at least one surfactant, and an aqueous solvent. The surface treated silica particles have a mixture of hydrophobic and hydrophilic silane surface treatment agents, where the ratio of hydrophilic silane surface treatment agent to hydrophobic silane surface treatment agent is greater than 1. The waterborne suspensions can be coated and dried to form nanostructured tie layers, especially tie layers to silicone or (meth)acrylate layers.
