All Available Paints and Coatings:
Lignin-Based Thermosets and Foams (RFT-542, 614)
NDSU Researchers have developed a process to modify lignin, so as to produce aceto-acetylated (AA-lignin) and methacrylated (MA-lignin) derivatives that are well suited for the production of thermosets. This technology enables modification of full-sized lignin molecules, and depolymerized lignin subunits, by attaching reactive groups to some or all of the hydroxy groups. The derivatized lignin has lower viscosity than (for example) kraft lignin. This makes it easy to handle and to control crosslinking reactions and can be readily crosslinked to form thermosets through several different mechanisms, including reactions with amines, polyisocyanates, or melamine-formaldehyde resins.
Hybrid Nanoparticle-based Anti-Corrosion Coatings (RFT-601)
Researchers at North Dakota State University have developed a novel nano-composite epoxy polymer coating. Our hybridized binary nano-filler coating overcomes several limitations with reproducible results. This hybrid filler system and modified epoxy prevent aggregation of the nanoparticles in the coating and its hydrophobicity prevents fouling and corrosion.
"Dirt-Resistant” Coating Enables Easier Removal of Biofouling Organisms, Graffiti, Ice Etc. (RFT-380, 496, 551, 572, 588, 596, 610)
Scientists at NDSU have developed a series of coating technologies around a siloxane-polyurethane backbone. These coatings have amphiphilic surfaces, which reduce the adherence of fouling organisms and materials.
Epoxidized Sucrose Esters of Fatty Acids (RFT-314, 422, 459, 488, 489, 502, 587)
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.
Novel Non-Isocyanate Siloxane-Polyurethane Coatings (RFT-517)
Glycidyl carbamate (GC) functional resins are used due to their high mechanical strength, toughness and abrasion, and chemical resistance associated with polyurethanes as well as the convenience of epoxy-amine chemistry. Webster et al. have combined these resins with polydimethylsiloxane to develop self-stratified coatings that yield coatings having low surface energy as well as reduce the hazards of isocyanates.
Styrenated Soybean Oil Derivatives as a Replacement for Naphthenic and Aromatic Rubber Processing Oils (RFT-512/513)
Scientists at NDSU have developed styrenated soybean oil derivatives that can be used as a direct replacement for naphthenic and aromatic oils in rubber processing. A particularly promising derivative is soybean oil (SBO) modified with polystyrene (SBO-PS). Tests using this bio-based rubber processing oil produced rubber with improved wet and ice traction with preserved low rolling resistance, while also providing better tensile properties, and similar durometer hardness and tear resistance, as compared with naphthenic and aromatic oils. These results demonstrate that non-toxic soybean oil derivatives can provide high-performing alternatives to the more toxic naphthenic and aromatic oils that are currently used for rubber processing. See for example the figure below, comparing naphthenic oil (NO), SBO-PS, and a 50/50 mixture of the two.
Polymers Derived from Bio-Diesel Waste for Road Dust Control (RFT-499)
Scientists at NDSU have developed a new material that can be applied to gravel roads for the suppression of road dust. The material is made from the huge waste stream that is generated during the production of biodiesel which is primarily glycerol and biodegradable or bio-derived fatty acid esters. The new material is made up of mono- and di-glycerides that are synthesized from a combination of waste glycerol and soybean oil triglycerides. Upon application to the road surface, the glycerides undergo crosslinking reactions to form larger, more stable molecules.
Acrylic Monomers Derived from Plant Oils – Synthesis and Use in High Value Polymers (RFT-462)
Scientists at NDSU have developed a one-step method to convert plant oil into acrylic monomers that substitute for petroleum-based monomers in the production of acrylic polymers. This method can use essentially any plant oil, animal fat, or other fatty esters as the raw material. The output is a combination of (meth) acrylic fatty monomers that can be used directly in the production of latexes, adhesives, surfactants, sizing agents, resins, binders, and other products that utilize acrylic polymers.
Plant Oil-Based Reactive Diluents for Coating and Composite Applications (RFT-438)
NDSU scientists have developed plant oil-based reactive diluents for coating and composite applications that possess both low viscosity and high reactive functionality. With these improved characteristics, these plant oil-based materials eliminate or reduce the need to be blended with petrochemicals thereby increasing the bio-based content of the product, which is environmentally more desirable.
Vegetable Oil-Based Polymers for Nanoparticle Surface Modification (RFT-413)
The extremely high surface area of nanoparticles provides many advantages over conventional particles with dimensions in the micron scale. For a variety of applications, it is necessary to suspend the nanoparticles in a liquid medium. Researchers at NDSU have developed a new plant-oil-based polymer technology focused on the application of nanoparticle suspension in water.
Bio-Based UV-Curable Oligomers for Coatings and Thermosets (RFT-365)
Scientists working at NDSU have developed branched and hyperbranched oligomers derived from a combination of soybean and cashew nutshell oils (CNSL). These oligomers can be either UV-cured (for coatings) or thermally cured (to produce thermoset polymers). Coatings incorporating this hyperbranched material had improved adhesion and impact resistance because the coatings were both strong and flexible. This material can be used in anti-corrosion and coatings and sealants, composites, inks, and adhesives, as well as directly in thermoset polymers. These oligomers impart improved material properties compared to current bio-based materials, and in some cases exhibit properties superior to even their petroleum-based counterparts.
Hybrid Bio-Based Coatings (RFT-310)
Researchers at NDSU have developed novel, hybrid and sustainable coatings. Sucrose and vegetable oil moieties form the base of the coatings.
Anti-Microbial Coatings for Medical and Underwater Biofouling Applications (RFT-260)
Scientists at North Dakota State University have developed a method to confer dual-action and broad-spectrum (gram +, gram -, and yeast) anti-microbial properties into polymers and coatings. The anti-microbial components are quaternary ammonium salts (QAS) and silver. The QAS component is attached to polysiloxane backbone – it may be strongly attached to provide a contact-active anti-microbial or may be gradually released and leachable. Silver may also be integrated, and the NDSU technology enables silver to be efficiently incorporated just into the outer portion of a surface by dipping into an appropriate silver solution. This means the silver need not be included throughout a polymer or coating layer but instead can be positioned right at the surface where essentially all the silver is available and provides a rapid anti-microbial effect once the surface is hydrated. The resulting materials include both a rapidly acting soluble anti-microbial component, and a longer-lasting contact-active component to kill microbes that make direct contact with the material.
UV-Curable Low Surface Energy Coatings for Fouling Release and Anti-Graffiti Paints (RFT-254)
A new type of UV-curable PDMS coating was formulated and characterized in this invention. Preliminary investigations have shown that the surface is hydrophobic and films are softer than that obtained from unmodified polyester. The basis of this invention is in the synthesis of novel unsaturated polyester compositions containing poly-dimethyl-siloxane (PDMS) by mixing these polyesters with co-reactants and photoinitiators, and curing the compounds using either visible or UV light to form coatings having low surface energy. Applications include marine, packaging materials, protective wood coatings, anti-graffiti coatings, easy-clean coatings, and release coatings. The uniqueness and importance of this invention pertains to its novel siloxane-modified unsaturated polyesters, UV curable technology (so no oxygen inhibition), low siloxane (cost-effective), and solvent-free nature.
Siloxane-Polyurethane Coatings for Anti-Graffiti & Marine Antifouling Applications (RFT-231)
This invention pertains to novel siloxane-urethane coatings that were developed from unique single-end-functional siloxane polymers. These reaction siloxanes are incorporated into polyurethane coatings and result in coatings having low surface energy but good adhesion and mechanical properties.
Modified Glycidyl Carbamate Resins Exhibiting Superior Mechanical Properties (RFT-226)
This invention pertains to novel glycidyl carbamate resins that have been modified with alkyl or ether alkyl groups. These resins have improved properties such as lower viscosity, which makes them good candidates for commercialization in the paint industry. In particular, it has the potential for application as a coating on aircrafts.
Sol-Gel Hybrid Coatings for Wide Range of Industrial Applications (RFT-225/240)
This invention pertains to the preparation of a two-component polyurethane coating formulation comprising: an epoxy-functional binder, and a blended curing component (having one sol-gel and one amine cross-linker.
Novel Polyurethane/Epoxy Hybrid Coatings (RFT-219)
This invention involves the preparation of a novel coating composition comprising a glycidyl carbamate functional resin, an aromatic epoxy resin, and a polyamine cross-linker. This coating formulation with the aromatic epoxy resin has improved corrosion resistance over coatings that do not contain the aromatic epoxy resin.
"Carrier Gas" Sensitizers for Improved Laser Ablation Performance of Coating Films (RFT-178)
NDSU inventors have developed polymer films and additives that can be used in polymer films such as polyol photosensitizers, carrier gas UV laser ablation sensitizers, and other additives that can be used in the preparation of such carrier films.
VOC-Free Waterborne Polyurethane Epoxide Resin and Crosslinker for Producing Tough and Flexible Coatings (RFT-154)
Scientists at North Dakota State University have developed a polyfunctional waterborne Glycidyl Carbonate (GC) resin, comprising oligomers that provide polyurethane properties with epoxide reactivity. These compounds can be dispersed in water to form a dispersion containing no volatile organic solvent.
Novel Environment-Friendly Coatings for Marine Applications (RFT-133)
Proprietary and novel, silicone-based compounds (and methods for synthesis), some of which incorporate tethered biocide moieties (for marine applications), have been developed that can be used in coating formulations to prevent or reduce fouling by marine life and related substances on ship surfaces.
