UrethanesIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Composite materials, including carbon fiber, are often preferred over conventional materials such as metal because they are lightweight, versatile and resilient. Carbon fiber is increasingly preferred for its traditional composite features and benefits and—as the latest fashion trends show — its fantastic finished appearance. Composite materials can be used to make not only a catwalk, but designer accessories as well.
The use of composite materials is particularly prevalent in the aerospace and transportation market sector because composites offer high-strength performance while keeping component weight down, thereby enabling better fuel efficiency and improved performance. Adhesive bonding of these composites offers many benefits and is widely accepted.
Unlike mechanical fasteners, adhesives maintain the composite material’s structure by eliminating the need to drill holes or puncture the composite. An adhesive bond can unitize the two pieces so they will not rattle or vibrate independently, which leads to fatigue. Adhesives further contribute to weight reduction because they simply weigh less than mechanical fasteners. In addition, adhesives provide a seam-free, perfect aesthetic finish, so products can be color-matched to the substrate material.Note de contenu : - BONDING SYSTEMS : Methyl methacrylates - Surface-activated methyl methacrylates - Modified epoxies/MS polymers - Two-component urethanes

TriclosanLe triclosan est un composé organochloré, proche des chlorophénols, qui possède des propriétés antifongiques et antibactériennes à large spectre. Il est aussi appelé 5-chloro-2-(2,4-dichlorophénoxy)phénol.
UrethanesIndex. décimale : 667.9 Revêtements et enduits Résumé : Novel, environmentally friendly antimicrobial coatings containing tethered biocide moieties derived from the ubiquitous biocide, triclosan, were synthesized and characterized using a high-throughput workflow. Triclosan was first modified with an acrylate functionality and, subsequently, copolymerized with hydroxyethyl acrylate and butyl acrylate using conventional free radical polymerization to form an array of acrylic polyol terpolymers. The polyols were characterized using nuclear magnetic resonance spectroscopy, differential scanning calorimetry, and gel permeation chromatography. Arrays of urethane coatings were produced from the array of acrylic polyol terpolymers and, subsequently, characterized using parallel dynamic mechanical thermal analysis, surface energy measurements, and various biological assays. The results of the biological assays showed that the coatings were effective toward inhibiting Staphylococcus epidermidis biofilm retention without leaching triclosan or other toxic components from the coating. The level of antimicrobial activity was found to increase with the content of triclosan moieties incorporated into the coating matrix. These results indicate that triclosan moieties tethered to a polymer matrix can impart antimicrobial properties via a contact-active, nonleaching (i.e., environmentally friendly) mechanism. Since S. epidermidis is one of the primary microorganisms associated with infection and failure of implanted medical devices, such as prosthetic heart valves, urinary catheters, and a variety of orthopedic implants, these coatings may have good potential for commercialization in some of these applications.

DiamineUne diamine est un type de polyamine contenant exactement deux groupes amine. Les diamines sont principalement utilisées comme monomères pour synthétiser des polyamides, des polyimides et des polyurées. La principale diamine produite est le 1,6-diaminohexane, précurseur du Nylon 6-6, suivie de l'éthylènediamine1. L'hydrazine (H2NNH2) n'est en général pas considérée comme une diamine puisque ce n'est ni une amine (pas de carbone), ni une dibase.

Reaction rates are calculated, and reaction kinetics are studied. Furthermore, Gaussian programs are used to calculate steric configuration and electronegativity of those two diamines. The electronegativity of TMEDA is greater than that of DABCO, but the steric hindrance of DABCO in nitrogen atom is smaller. Steric hindrance plays a more important part in reaction kinetics, which makes the reaction to be catalyzed by DABCO at a faster rate. Finally, activation energy, activation enthalpy, and activation entropy for the reaction are calculated, followed by the discussion of reaction mechanism.
