Epoxy coatings have many excellent properties, such as adhesion, corrosion resistance and hardness. However, bath solventborne epoxies and lower-VOC waterborne analogs have deficiencies such as brittleness, short potlives and must notably, pour durability towards UV light. Due to their pour weathering characteristics, epoxies tend tu chalk, yellow and lose gloss quickly when exposed to sunlight. A hybrid technology has been described that maintains the best qualities of epoxy chemistry, while im¬proving upon some of its weaknesses such as flexibility and UV durability. The hybrid technology joins acrylic and epoxy chemistries into a single waterborne offering that can then be formulated into 2K waterborne coatings for steel and concrete. The AEH represents a new method for supplying epoxy resin into a mixed 2K coating. The epoxy resin is hosted in acrylic latex particles and becomes available for cross-linking with a hardener after water begins to leave the film and particle coalescence starts. The AEH system is versatile in that either acid-functional acrylic or amine hardeners can be used. The result is a coating technology with a unique balance of properties, including long potlife, excellent corrosion resistance, good flexibility, and excellent UV durability and weatherability.

ThermodurcissablesIndex. décimale : 667.9 Revêtements et enduits Résumé : An oxazoline with an unsaturated side chain was reacted with m-chloroperbenzoic acid in order to convert the unsaturation to oxirane moieties. The conversion of double bonds to oxirane is high provided a significant excess of the perbenzoic acid is used. The conversion was monitored using NMR spectroscopy. The unsaturated oxazoline was reacted with an acid-functional acrylic, and the resulting adduct was reacted with m-chloroperbenzoic acid to epoxidize the pendent unsaturation. Again, a significant excess of the peracid was required to reach high conversion of the double bonds. The epoxidized oxazoline and the modified acrylic were evaluated in thermoset coatings over metal panels. The properties of the films ranged from moderate to good depending on what species was used as a crosslinker.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Painting of a Zn-21wt%Al-2wt% Cu alloy, with four different superficial conditions, was carried out without difficulties using conventional paint systems recommended for applications over galvanised steel and even a common system to paint steel. The preparation of the ternary alloy surfaces by means of two phosphating treatments led to a slight improvement in the performance of the paint systems in exposure tests to a NaCl solution, a SO2 atmosphere and to weathering. Hardly any difference was observed among the superficial conditions in the adhesion tests. After 11 years of atmospheric exposure, specimens of the ternary alloy coated with the epoxy-polyurethane or the chlorinated rubber paint systems did not present major symptoms of degradation.

Traîtements de surfaceIndex. décimale : 667.9 Revêtements et enduits Résumé : Poly (2-methacryloyloxyethyl phosphorylcholine) (PMPC) has been widely used for surface modification of titanium (Ti) alloys to improve antifouling properties and blood compatibility. To achieve antifouling and anticoagulant capacities via a facile and efficient technique, PMPC coatings were covalently immobilized on a Ti surface simply by a sequential dip-coating method. The Ti surface was first dipped into hydrochloric acid (HCl) solution to remove surface contaminants and acquire a hydroxyl-enriched surface. Then, the surface was dipped into dopamine solution to acquire the surface bearing –NH2 groups. N-acryloxysuccinimide solution was used for introduction of double linkage which could graft with PMPC via in situ free-radical polymerization. Thus, the surface modification processes were under mild conditions and easy scale up. The obtained PMPC coatings endowed the Ti surface with smooth finish and relatively high packing density. Water contact angle measurements showed that the hydrophilicity of the Ti surface was markedly improved by coating PMPC with the water contact angle of 6.2°. Furthermore, the PMPC coatings could effectively resist protein adsorption and suppress platelet adhesion and activation. The facile and efficient method of immobilization of PMPC on a Ti surface could be promising for a variety of cardiovascular applications.
