2 This document describes an ambiant-cure epoxy-siloxane coating, exhibiting excellent corrosion resistance, substrate adhesion, flexibility, weatherability and superior chemical and impact resistance after curing.The chemical combination of Epoxy and Siloxane results in polymers with higher performance characteristics than can be achieved by the physical combination of all polymers. The chemical combination provides the basis for the joined polymeric strength, weathering durability, high temperature properties, and radiation resistance, gloss and color retention and corrosion protective properties of the polymers, whilst overcoming the brittleness of inorganic structures.Possible substrates include: concrete, cementious products, arhitectural blocks, internal / external pipes, tanks, containers, off-shore oil drilling platforms, metallic framework, bridges, gas turbine engines, heat exchangers, interior / exterior of ships and aerospace equipment.
3 Executive SummaryThe cost of corrosion in the U.S. piping industry is more than $8 billion annually. To eliminate this problem, approximately 10% of all new U.S. steel pipes are treated to resist corrosion. For the same reason, expensive corrosion-resistant stainless steel pipes and pipe lining are also being used.Oil and gas well pipes, normally consist of relatively low cost, low carbon steel susceptible to hydrogen embrittlement, hydrogen sulfide induced corrosion, and chloride stress corrosion and cracking. While efforts have been made in the past to overcome such problems, they have not met with wide acceptance. For example; while the entire pipe, or pipe liners may be formed from stainless steel, this is a far too costly solution. Stainless steel liners have been proposed but it has been found that hydrogen diffusing into the clearances between the liner and pipe bore causes problems such as hydrogen embrittlement, and deformation of the liner when the hydrogen expands.Biro Technologies provides a more cost-efficient, more effective solution for internal pipe coating, a new generation of Epoxy-Polyamidoamine Zinc primer and Epoxy-Siloxane top coatings that are in every way superior to the old coating products.
4 Executive SummaryContamination of exposed structural surfaces with chemical or biological material can occur in both civilian and military contexts. Contamination can occur accidentally, such as during the conveyance of hazardous materials from one site to another, or can occur on purpose, such as in chemical or biological warfare. Such materials can remain for a significant period of time on exposed surfaces such as equipment, vehicles, aircraft, buildings, etc.Photocatalytic coating composition containing Epoxy-Siloxane polymer that hold the photocatalyst in place without degrading the desired performance of the coating.The coating may be applied by conventional coating methods to organic or inorganic structured surfaces where photocatalytic activity is desired.The coating after dries leave an adherent, flexible, durable, and long-lasting photocatalytic coating having a large surface area and exhibiting high surface activity against pathogens and pollutants such as bacteria, viruses, mold, fungi, and volatile organic compounds.Photocatalytic coating the solution for self cleaning, self-decontaminating and anti-bacterial application.
5 Executive SummaryIce build up is a serious problem and major economic impact in the aircraft industry.Ice-phobic coatings could benefit the Aircraft Industry, NAVAIR and Air Force for de-icing composite and aluminum wings and fuselages. With respect to NAVAIR, aircraft de-icing is an important function at the many Navy facilities that support aircraft operations. Because of the high cost of purchasing deicing fluid, and the potential negative impact of glycol discharges on the environment it is optimal to minimize the volume of propylene glycol or ethylene glycol used in its aircraft de-icing operations.Ice-phobic coating significantly outperforms other ice-phobic coatings, providing measureable economic and environmental benefits.Ice-phobic coating significantly reduces ice adhesion when applied on aluminum surfaces compared to other commercially marketed ice-phobic coatingsThe ice-phobic coating could be applied as a very thin film to aircraft surfaces without significantly increasing the weight.

14 Appendix D. Detailed Product Information Epoxy-Siloxane Corrosion Protective CoatingFor many years the conventional anti-corrosive paint systems for long lifetimes has been to utilize zinc primers. The type of primer normally specified has been zinc ethyl silicate.The reason for using this type of technology giving zinc-zinc metal contact and, consequently, excellent cathodic protection properties akin to those obtained from galvanizing.The new Epoxy-Polyamidoamine zinc primer and Epoxy-Siloxane finish coating has many improvements comparing to the zinc ethyl silicate primer such as:- Zero VOC- Excellent adhesion- Surface tolerant (surface preparation may be less than ideal)- Much higher flexibility- Long shelf life (2 years)- Simple processing (no hydrolysis)Typical uses of Epoxy-Polyamidoamine zinc primer and Epoxy-Siloxane finish coating are to protect ferrous surfaces in aggressive atmospheres against corrosion, such as: industrial and marine atmospheres (ship building, oil drilling platforms, harbor installations) Chemical attack (internal coating of tankers, containers, pipelines), bridges, structural steel etc.
15 Appendix D. Detailed Product Information Epoxy-Siloxane Ice-Phobic coatingIce at surfaces often cause serious safety risks and damage in technical applications such as airplanes, ship decks, cables etc.Epoxy-Siloxane ice-phobic coating with a low surface energy dynes/cm2 inhibits ice formation and lowers the adhesion between ice and the substrate surface.Epoxy-Siloxane ice-phobic coating is characterized as a smooth anti adhesive surface with local, regularly distributed ice nucleation points, which are separated from each other. Small local ice nucleation sites with higher surface energy are surrounded by anti adhesive ice repellent segments with lower surface energy.The adhesion of the generated ice crystals is reduced dramatically both in strength and contact area. The removal of the generated ice crystals is possible just with the flow of the brine along the surface.The most desirable solution to the de-icing problem, would be to apply a material that prevents ice from building up in the first place rather than taking it off after the fact.
16 Appendix D. Detailed Product Information Epoxy-Siloxane Antifouling CoatingsThe long-used “tributyl tin” anti-fouling compounds are now banned. Epoxy-Siloxane Antifouling technology shows good long-term performance by effectively shedding marine organisms regularly over a long service life.Types of anti-fouling applications:Nanostructured. Incorporating nanoparticles in the Epoxy-Siloxane antifouling coating which remain permanently as part of the coating. Due to their small size, nanoparticles will remain in the lattice of the coating and cannot leach out but continuously release ions that provide long-term anti-fouling performance.Low friction. Epoxy-Siloxane antifouling release coating is cleaned by sufficient movement through water. The low friction antifouling technology minimizes the attachment of marine organisms to a ships hull due to the low friction characteristics of the coating, which uses Epoxy-Siloxane polymer.This low-friction type antifouling coating is very eco-friendly, as it doesn’t contain any biocides or potentially hazardous materials.
17 Appendix D. Detailed Product Information Epoxy-Siloxane Photocatalytic CoatingsEpoxy-Siloxane Photocatalytic coating a novel and new application field, with self-cleaning self-decontaminating and anti-bacterial properties.The unique Epoxy Siloxane polymer with strong adhesion and transparency is the best delivery system to hold the nano-sized photocatalysts in place without degrading the delivery system.The special composite structure of the coatings can help separation and transportation of the photo carrier, therefore having a high level of photocatalytic activity and a long lifespan. When waste water or polluted air passes its surface, organic pollutants are degraded by photocatalysis so that it is self-cleaning. This method is effective on all types of organic substances and will degrade them into carbon dioxide and water. It is efficient, energy-saving and has no secondary pollution.Epoxy-Siloxane Photocatalytic coating also decomposes organic matter by oxidation, specifically bacteria, viruses and germs. The inorganic anti-bacterial nano particles kill bacteria and inhibit propagation of pathogens, molds and epiphytes to prevent disease spread. It has a long term effect on killing bacteria, no harm to human beings and no pollution on environments.
18 Appendix D. Detailed Product Information Defense against graffitiEpoxy-Siloxane coatings are relatively new and offer an extremely long-lived surface from which graffiti, fly-posters and other soiling can be removed easily and repeatedly, using safe and mild agents, without the loss of properties, performance or appearance of the coating itself. This type of coating has release properties similar to those of non-stick domestic kitchenware. Any soiling can easily be removed using aqueous surfactant/detergent mixtures, or at worst, benign chemical mixtures which have no effect on the coating itself, resulting in a truly permanent anti-graffiti coating.Epoxy-Siloxane Coating offers an excellent defense against graffiti and is easily cleaned without leaving a shadow after cleaning.
19 Appendix D. Detailed Product Information Nuclear radiationHigh energy neutron radiation is present in nuclear reactors, which can lead to degradation processes in the materials of critical components.Under the effect of neutron bombardment,the substances in Epoxy-Siloxane coating are not converted into radionuclides and has no substances in the matrix which would have an adverse effect on the reactor.Epoxy-Siloxane Coating is essentially unaffected by nuclear radiation and has an excellent rating for decontamination. The coating performed without any defects on irradiation to a cumulative dose of 5500 megarad as tested.Organic coating systems show considerably lower decontamination factors with typical values of 500 to 1000.
