Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Wood has long been used as a sustainable building material for thousands of years ; however, it needs to be coated with a variety of products giving it protection against the elements and for decorative effect. Solvent-based alkyd coatings have proved to be very effective at protecting wood against the negative effects of the environment and solvent-based (SB) alkyds are still widely used for the production of high quality gloss paints and varnishes. However, the use of these materials is now being curtailed due to their high solvent content and the need to comply with legislation restricting the levels of Volatile Organic Compounds (VOCs) in decorative paints. For example, the European Directive 2004/42/EC now limits the VOC content in gloss trim paints to 300g/lit, see Table 1 for more details. In order to achieve an acceptably low viscosity at high solids, it has been necessary to use lower molecular weight and increased oil content alkyd resins with the consummate poor drying and increased yellowing. In response to this, paint producers are now moving towards waterborne (WB) systems such as alkyd emulsions and acrylic dispersions with much lower VOC levels.

Transparence (optique)Index. décimale : 667.9 Revêtements et enduits Résumé : Synthesis, characterization, and coating performance of castor oil (CO)-based waterborne hyperbranched polyurethane acrylate (WHPUA) emulsions are highlighted in this work. Herein, a second-generation CO-based hyperbranched polyester (C20) was synthesized by introducing the renewable CO as a B3 core and dimethylolpropionic acid as an AB2 monomer via a pseudo-one-pot condensation procedure. Three types of CO-based WHPUA emulsions were prepared through the addition of the hyperbranched C20 with maleic anhydride (MA) and the isocyanate-bearing semiadduct (IPDI-HEA) at different MA/IPDI-IH molar ratios without the addition of any emulsifiers. The prepared emulsions were further formulated into UV-curable coating formulations and exposed to a medium-pressure mercury lamp. Consequently, the obtained UV-cured coatings exhibited outstanding adhesion performance, excellent transparency, and an acceptable degree of final double bond conversion. Owing to a relatively low concentration of hydrophilic units and a large number of acrylate functionalities in the waterborne oligomer, the obtained films were endowed with high crosslinking density and low hydrophilic nature, thus producing enhanced tensile strength, pencil hardness, water resistance, and chemical resistance. Due to their combination of renewable materials, a waterborne system and a UV-curing technique, these CO-based WHPUA emulsions offer promising opportunities to be used as environmentally friendly coatings.

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : I have mentioned in the earlier chapter an outline about how the Bases are categorised. Now we will see how to categorise them. In short each base will be used to tint a particular spectrum of shades. All of them are categorised as Base I, II, III and Dark Base (D-BASE) or Clear Base. Some types of paint may not have three bases due to limited spectrum of shades they wiII be used for tinting. For example Base I is used to tint to get all light or most of the pastel shades, as it contains higher percentage of Rutile. Base II is used to tint and get slightly darker shades than the pastel shades, Base III will give comparatively still darker shades than Base II, and D-Base is used only for tinting to get the dark shades, like Dark Mikado, Terracotta, Mogul Green, Dark Green or Pinewood Green etc and the list goes on. Hence as said earlier the formulator has a tough job to formulate with the correct percentages of Rutile and Extender Pigments and Emulsion, in order to get the shades accurately at the same time economically without the use of higher percentage of tinters. In other words, every paint manufacturer makes multiple bases into which tinters are added at the point of sales. What is common to all is that the bases have decreasingly less white pigment in the "deeper" bases. If you paint with one of these bases without tint, you will get an extremely poor covering paint. A "deep" base paint will have I iterally no white pigment in it, however, acrylic paints look white in their wet state but dry and clear. If you should paint with a deep base without tint, you are essentially putting on a coat of acrylic varnish. A white tint base will have the full complement of white pigment in it, but its coverage will be somewhat lacking. Even a few drops of raw umber or black tinter will dramatically increase its coverage. Pigment does increase the protective value of coatings. A solid hide exterior stain will give far superior protection to wood over that of a semi-transparent stain because the higher concentration of pigment blocks the sun's UV rays.

Revêtements en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Most water-based architectural stain blocking primers typically have only moderate stain blocking performance, and they are designed to lock stains in the primer coat rather than block stains. This leads to a major performance difference compared to solvent-based primers. Since the stain is visible in the dry film when a bleeding substrate is coated with water-based primer, the painter cannot tell with any degree of certainty if the stain will migrate into the topcoat. Novel cationic water-based primers offer far superior stain blocking and are like solvent-based primers because many stains are blocked by the primer coat rather than locked into the primer coat. For these cationic primers, however, manufacturing procedures and raw materials are different from those typically used in conventional anionic architectural coatings.
