Abstract: A coating, system comprises 30 to 90 parts by weight of a bioresin component and 10 to 70 parts by weight of an isocyanate component, based on 100 parts by weight of the coating system, and has a percent solids of greater than 60%. The bioresin component comprises an acrylic polymer and a biopolyol formed from a natural oil. A method of forming a coating on a substrate with the coating system comprises the steps of combining the bioresin component and the isocyanate component to form a reaction mixture having a percent solids of greater than 60 percent, applying the reaction mixture onto the substrate, and curing the reaction mixture to form the coating on the substrate.

Abstract: Provided herein are novel and improved weight coating systems suitable for use with pipes, particularly pipes that are submerged in liquid, such as water, in environments including oceans, seas, marshes, lakes and rivers. The novel coating systems provided herein comprise an aggregate and a polyurethane binder, wherein the polyurethane binder is a two -component composition comprising an isocyanate component and an iso-cyanate-reactive component. The coating systems provided have increased durability, as well as flexibility allowing for efficiencies related to transportation, storage, use and resistance to corrosive effects. Furthermore, the coating systems are cost effective and have minimal or zero impact on the environments in which they are utilized.
