Coatings containing polar additives and their use as ice shedding surfaces.

This invention relates to advanced polyurea-siloxane (PU) coatings modified with natural deep eutectic solvents (NADES) and co-curing additives to improve ice-shedding performance under real-world conditions. The coating system incorporates choline chloride-glycerol NADES into a moisture-curable polymer matrix, enabling the formation of microphase-separated...

Furan-derived compounds and their use in epoxy coatings

Diol compounds derived from furan, along with their epoxy-functional derivatives, can be synthesized and used either individually or in mixtures to create cured coatings. Coatings made from these compounds demonstrate a favorable balance of physical and mechanical properties. Additionally, these coatings are primarily biobased, making them suitable...

Zwitterionic copolymers as surface modifying additives for marine fouling-release coatings

Block copolymers of poly(dimethylsiloxane) and monomers containing zwitterionic groups were synthesized and incorporated as additives in a polyurethane coating and evaluated for their ability to improve the coatings' fouling-release properties. Homopolymers of the zwitterionic monomers were also prepared and incorporated into the polyurethane coating...

UV Cured Coatings from Highly Functional Epoxy Resins

Scientists at North Dakota State University have developed a method to produce epoxidized sucrose esters of fatty acids (ESEFAs). These are macromolecules with a rigid sucrose core from which 8 arms extend, the arms derived from fatty acids. ESEFAs have extraordinary versatility with respect to potential uses and manufacturing processes. This versatility...

Anchored Polysiloxane-Modified Polyurethane Coatings and Uses thereof

This patented technology introduces a next-generation polyurethane coating enhanced with anchored polysiloxane segments. Unlike conventional fouling-release or protective coatings where silicone migrates or leaches over time, this formulation chemically anchors the polysiloxane within the polymer network, ensuring long-term durability, hydrophobicity,...
