Title:
ULTRA HIGH STRENGTH COATING AND COMPOSITES
Document Type and Number:
WIPO Patent Application WO/2019/140447
Kind Code:
A1
Abstract:
Method of producing a high strength (with improved tensile strength and elongation at break properties), high quality, cost effective, nanoparticle enhanced polyurea, polyurethane, and epoxy composites with chemical bonding into polymer backbone. The mechanical properties of tensile strength and elongation at break improves concurrently and significantly with tensile strength increasing well over 300%. The polymer/nanoparticle composite can be produced cost effectively as a high quality coating system or in nanoparticle concentrate forms.
