Chanvre et constituantsLe chanvre ou chanvrier (Cannabis sativa L.) est la seule espèce du genre botanique Cannabis. Ce terme latin est souvent utilisé aussi comme nom vernaculaire pour distinguer les variétés de chanvre cultivé à usage industriel des variétés de cannabis à usage récréatif ou médical. C'est une espèce de plante annuelle, de la famille des Cannabaceae. La graine de chanvre s'appelle le chènevis.

Traction (mécanique)Index. décimale : 667.9 Revêtements et enduits Résumé : Since alkyd resins include hazardous solvents, converting alkyds into waterborne hybrid polymers is an essential research topic. Here, alkyd/styrene acrylic waterborne hybrid polymers were synthesized in the presence of monomers, water, emulsifiers, and an initiator by using synthesized alkyd resins at 0%, 5%, 10%, and 15% ratios based on the total monomer ratio. A mini-emulsion technique and a semi-batch polymerization method were used to synthesize the latexes. Two different biosources, tall oil fatty acids (TOFA) and hemp seed oils (HSO), were used to synthesize the alkyd resins. Synthesized waterborne hybrid latexes and their films were analyzed by using FTIR, NMR, particle size, MFFT, TGA, DSC, CA, AFM, and mechanical tests. It was determined that the type and concentration of the alkyds affected the viscosity, particle size, Tg and MFFT values, and appearance. It was also identified that alkyd incorporation took place with grafting and that the alkyd concentration was particularly effective in increasing the particle size. In addition, experiments were carried out on waterborne paint systems for exterior paint by using synthesized hybrid polymer emulsions. It was observed that the alkyd content was not effective in changing the paint color in hybrid latexes. As a result, it is suggested that hybrid waterborne latexes could be used for exterior paints.

Revêtements en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : The popularity of wooden decks is increasing as greater numbers of people around the world not only become aware of the wide variety of wood species that are now available but also recognise the green aspects of wood as a renewable resource.
A wood deck, however, only creates a unique outdoor living space and brings value to a home if its beauty is maintained. Wooden decks are investments that require maintenance and these ongoing costs are often not considered. Yet, in many cases, the natural resistance of woods used today to weathering and insects are reduced due to the inability to allow the extensive ageing required to develop such properties. Therefore, the coating industry must step in and provide the needed protection.Note de contenu : - Importance of protection

ViscositéIndex. décimale : 667.9 Revêtements et enduits Résumé : Oxyethylene (PEO)/oxypropylene (PPO) triblock polymers are added to colorant formulations to determine the influence of molecular weight and other structural variances on the rheology and color development of tinted latex paints. Waterborne coatings are a matrix of many coating components. In this study, a 108- or a 600-nm latex was thickened with a nonassociative thickener, hydroxyethyl cellulose, or an associative telechelic HEUR thickener. Triblock polymers with internal PPO segments and PEO terminal segments added as a dispersant to colorant packages, lead to better color development than PPO/PEO/PPO triblocks dispersants in carbon black (CB) tinted paints. The increase in color development with high molecular weight (MW) triblocks starts at a very low concentration (2 mM) and plateaus in a Langmuir-type adsorption isotherm. Lower molecular weight triblock polymers also exhibit this behavior in CB-, red-, and yellow-tinted latex coatings; however, increasing the terminal PEO segment sizes leads to better color development only in the CB-tinted coatings. With large PEO terminal units red and yellow tints are high only at very low concentrations (2 mM) of the triblock. This parabolic response in color development, in contrast to CB-tinted formulations, is attributed to the high surface area and porosity of CB that limits the amount of large PEO segments interacting with the talc particle present at twice the volume fraction of the colorant. With the lower surface areas of the red and yellow colorants, the interaction of the large PEO terminal segments with talc particles accounts for the limited triblock concentration for which good color development is observed. This can be reversed by decreasing or eliminating talc from the formulation.

Revêtements en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Industrial wood coatings encompass several market areas, including furniture, kitchen cabinets, building products, and decorative coatings.
Requirements for these markets largely depend on their field of application.
Exterior performance is focused on high durability and protection against humidity, while interior coatings require properties such as scratch, chemical and abrasion resistance. One of the largest sectors of the interior market is the furniture industry.
Several resin technologies are being used by coatings formulators in this market, including solventborne (SB), waterborne (WB) UV polyurethane dispersions (PUDs), and self-crosslinking acrylics. Several criteria are of importance in considering which technology to use.
Each technology has advantages and disadvantages, and a comparison has been summarized based on the criteria in Figure 1. The dominant technology used in North America is solventborne, including nitrocellulose (NC) and acid cure conversion varnish. These coatings have many benefits, including fast dry time and very high gloss, and they enhance the wood appearance. They are also very economical and can be easily applied by spraying, rolling, curtain coat, and dipping.Note de contenu : - Fig. 1 : Resin technology comparison
