Universitat Politècnica de Catalunya - UPC posted this:PC-ProTec A novel, highly effective zinc free anticorrosive additive easily dispersible in priming paintsPC-ProTec is a new technology uniquely positioned as a safer alternative to replace toxic anticorrosive additives, mainly zinc and its compounds, typically used in paint formulations to protect metal structures. The novel zinc-free anticorrosive pigment, which is applied in very low concentrations (0.3-1.5 wt %), is based on poly(alkyl thiophene acetate)s. This technology meets the new environmental regulations that restrict the use of zinc. Partners to further develop the technology and/or to establish commercial agreements along with technical cooperation are sought.

Fundació URV posted this:Environmentally friendly processing of thermosets by two-stage sequential aza-Michael addition and free-radical polymerization of amine-acrylate mixturesEnvironmentally friendly preparation of thermosets for applications on thermosensitive substrates. A two-step curing process, which consists in an Aza-Michael addition at room temperature, followed by UV radical polymerization of acrylates or methacrylates amine formulations without the need of adding solvents. The presence of amines in the structure suppress the radical inhibition by oxygen, which is a typical drawback in radical polymerizations. The invention allows leading the curing in two separate stages with a stable intermediate material, being the process controlled by the amount of amine in the formulation.
DIT Hothouse posted this:iSeal: Advanced Surface Treatment for Protection against TribocorrosionThis invention is based on the application of a hybrid organic/inorganic treatment onto an exposed surface – either as a stand-alone treatment or as a sealant. The treatment is applied using an electrochemical deposition technique, allowing for the development of conformal coatings, irrespective of design complexity. Layer thicknesses are low (10-100nm) but resistance in corrosive marine environments indicate corrosion rates comparable to technologies currently employed by the aerospace and automotive industries. Corrosion rates are reduced by between 103 and 105 times, dependant on the nature of the porous coating. Tests on metallic coatings indicated a reduction in corrosion rates of approximately 103-104 while tests on ceramic coatings indicated a reduction in corrosion rates of approximately 105. By applying the hybrid treatment as a sealant treatment onto a porous wear resistant coating, concerns regarding the effect of mechanical damage are dramatically reduced. In addition, surface roughness levels are similar to electropolished finishes.

Universidad de Alicante posted this:New family of dyesThe main innovative aspects of this technology regarding current methods of synthesis are: • The indolizine dyes are obtained in one step from commercially available materials, unlike current procedures, which involve multiple steps. This is an advantage in the production process, as it reduces costs, increases the final yield and less waste is generated. • The procedure is based on a very simple treatment which produces indolizine dyes in yields higher than 70%. • The present invention does not require the use of inert atmosphere, dry solvents or physical activation (heat or radiation) to obtain the final product. • Unlike other methodologies for preparing indolizine dyes (requiring temperatures around 100°C), this process is carried out at room temperature and atmospheric pressure, which simplifies the method and decreases production costs. • This is an environmentally friendly technology because it does not use solvents such as dioxane, pyridine, chloroform or benzene, which are used in other methods and are characterized by their high toxicity and demonstrated carcinogenicity. • The selectivity of the reaction is very high. The indolizine dye is obtained with absolute control, obtaining a single isomer of the ten possible.
