For many years manufacturers have tried to do three things in thei finishing operations :
- Reduce VOCs by switching from solvent borne coatings to environmentally-friendly waterbore coatings
- Spray electrostatically to increase transfer efficiency
- Change colours fast
Individually, each task could be done but to combine the benefits of all three into one solution was impossible. Due to high conductivity of waterborne coatings, manufacturers must typically decide between spraying non-electrostatically, where they lose transfer efficiency but have to deal with expensive and unreliable solutions such as isolation systems or external charging. Then came voltage block technology that provided a safe, reliable and efficient way to spray waterborne coatings electrostatically. Unfortunately, the colour change process with a voltage block system was still slow and costly. However, with recent advances in voltage block desing, you can now get all of the cost savings of spraying electrostatically and achieve fast, efficient colour changes, without replacing current equipment.Note de contenu : - WHAT IS ELECTROSTATIC COATING AND WHY IS IT SO IMPORTANT ?

Polyurethane dispersions based on renewable resources are, especially when NMP-free, an environmentally sound alternative to solvent-based varnish systems. Besides good chemical resistances and mechanics which can absolutely compete with existing systems, these products offer excellent systems wood warming and are mainly based on renewable/sustainable resources. Therefore and with regard to the example of the LUD-Leinöl-1 it is absolutely imaginable that such kind of binder system will provide an appropriate alternative to solvent-containing systems (eg 'Teak oil' etc) in future and may replace them sometime.En ligne : https://drive.google.com/file/d/1_zX99Xmzx-ZQGq3hgW3vd7zOThKR2lrz/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=27307

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : The performance and appearance of pigmented waterborne coatings strongly depend on the degree to which the various particles (pigments and polymer) are dispersed throughout the dried film. The ideal state of dispersion is usually when all particles are reduced to and remain as non-flocculated primary particles.
Polymer particles, pigments and fillers, not optimally dispersed can adversely affect the ability of the coating to provide adequate barrier (to electrolytes, water, gases, etc) properties. In addition, poorly dispersed pigments and fillers can affect the ability to add colourant as well as paint colour stability under the applied shear forces that can occur during application (eg brushing and spraying).Note de contenu : - More efficient interaction between pigment and latex polymers
- Experimental design
- Improved gloss through more even pigment dispersion
- Improved hiding power

PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.
Revêtements:PeintureIndex. décimale : 667.9 Revêtements et enduits Résumé : Epoxy polyamide based paint was coated on glass plate and mild steel panels inoculated with pseudomonas bacterial species. The weight gain experienced in the coated panels after 90 days of immersion, indicates the polymer-coated surface. Similarly the impedance data revealed that the enzyme produced by the pseudomonas did not influence the coating surface. But after 90 days the resistance value has decreased due to diffusion of water into the polymer coated surface. The FTIR analysis confirmed the epoxy polyamide coating has strong resistance to microbial activity resulting in no biodegradation. Note de contenu : - Preparation of coated panels
