Revêtements en phase aqueuse -- AdditifsIndex. décimale : 667.9 Revêtements et enduits Résumé : Several plant-based alternatives to fossil fuel-based (meth)acrylate monomers are available. Most promising types include the diesters of itaconic acid and esters of (meth)acrylate monomers prepared with plant-based alcohols. Other plant-based monomers show issues with either too slow, or too high reactivity, or with lacking commercial availability. Applying the preferred and commercial available monomers in emulsion polymerisation can yield water-based and partially plant-based binders showing film properties in industrial coatings that are similar to those found for paints based on commercially available fossil-fuel based binders. At this point in time, polymeric binders with plant-based contents of around 40% can be achieved (calculated on total carbon content). New developments with even higher plant-based contents are, however, foreseen to be available within five years from now. Note de contenu : - Table 1.

Réticulation (polymérisation)Index. décimale : 688 Autres articles, technologie des emballages Résumé : This study shows that UV- or EB-cured acrylate chemistries have the necessary performance characteristics for sealant and potting compound applications. Requirements such as hardness, elongation, resistance to dry and humid heat, and chemical resistance can be met when the correct monomers and oligomers are used. Cured photopolymer properties can be predictably manipulated by changing the backbone structures and molecular weight of the various components. Polyether-backboned monomers and oligomers showed the best overall performance and maintained that performance when exposed to both dry and humid conditions. Note de contenu : - Learning what works

Réticulation (polymérisation)Index. décimale : 667.9 Revêtements et enduits Résumé : A new method for simplifying the preparation of unsaturated latex was investigated. Four divinyl monomers were designed, and based on quantum chemical calculations, (z)-4-(2-(acryloyloxy)ethoxy)-4-oxobut-2-enoic acid (cis-AEOEA) was selected as the only nonelectron-donating divinyl monomer whose active double bond is prone to polymerize, while the inactive one is left in polymer form. The inactive double bond can also be activated by the formation of charge transfer complex polymerization systems with electron-donating comonomers and activity that is in direct proportion to the electron-donating ability of comonomers. This result was proved using an orthogonal experimental design L934, and the UV-curing performance of unsaturated latex membranes was studied.

StyrèneIndex. décimale : 667.9 Revêtements et enduits Résumé : Styrenated sucrose esters of soybean fatty acids were successfully synthesized and the coatings properties were found to be comparable to a commercial styrenated alkyd while having lower volatile organic content at comparable solids content. A series of reactions were performed which varied the percent styrene incorporated into the resin. The dry time was significantly reduced as the styrene content increased which was a result of having more hard polystyrene chain segments. Tack-free times of ?30 min were observed for resins containing high amounts of polystyrene. Nuclear magnetic resonance spectroscopy indicated residual bisallylic hydrogens were present which are capable of further crosslinking through autoxidation after film application. The addition of cobalt and zinc driers reduced the drying time which indicates that autoxidation is occurring. Furthermore, the styrenation reaction was extended to make water-reducible resins. These resins were crosslinked with a melamine–formaldehyde resin resulting in biobased thermosets having high solvent resistance, high hardness while retaining good flexibility.

Lin et constituantsLe lin cultivé (Linum usitatissimum) est une plante annuelle de la famille des Linaceae cultivée principalement pour ses fibres, mais aussi pour ses graines oléagineuses. Les fibres du lin permettent de faire des cordes, du tissu (lin textile pour ses qualités anallergiques, isolantes et thermorégulateurs), ou plus récemment des charges isolantes pour des matériaux de construction. Les graines sont utilisées pour produire de l'huile de lin pour l'industrie de l'encre et de la peinture, pour la consommation humaine et animale, à cause de sa richesse en oméga 3.
Le lin est une des rares fibres textiles végétales européennes. Elle a comme caractéristiques la légereté, la rigidité et la résistance et comme particularité d'être une fibre longue (plusieurs dizaines de centimètres), par rapport aux fibres courtes (coton, chanvre) ou moyennes (laine).

PolymérisationIndex. décimale : 668.4 Plastiques, vinyles Résumé : Natural fibers are light, economical and renewable. Which is why they are being increasingly considered for structural components. However, when moisture penetrates into the fibers, their mechanical properties suffer. Cavity polymerization can close the fiber cavities and prevent the natural fibers from absorbing as much water.
