ZincIndex. décimale : 667.9 Revêtements et enduits Résumé : Low-VOC waterborne (WB) Zn-rich primers and high performance WB epoxy primers have been developed based on novel Cashew Nutshell Liquid (CNSL)-derived curing agents for industrial and protective coating applications. These unique WB phenalkamines were synthesized from a natural, non food chain and renewable biomaterial and could help formulate WB primer systems that meet stricter volatile organic compound (VOC) regulations as well as high performance requirerments.
This article presents the latest performance studies of new phenalkamine-based WB Zn-rich primers and epoxy primers, and discusses the challenges associated with such formulations.
New 2K WB Zn-rich primers were formulated with a water-free phenalkamine curing agent. The study results showed the WB Zn-rich primers had good compatibility with various commercially available solid epoxy dispersions and delivered good cure and mechanical properties ; importantly, those WB Zn-rich primers provided superb adhesion to both metal substrates and commercial polyurethane (PU) topcoats without the use of adhesion promoters. Excellent corrosion protection and good resistance to undercutting of the scribe were observed after 3000-h Q-Fog exposure.
Additionally, newly developed WB high performance primers based on zero-VOC WB phenalkamines were evaluated either in combination with WB Zn-rich primers or by being directly applied over metal substrates was found that those WB epoxy primers could enhance corrosion protection as mid-coats to WB Zn-rich primers ; when being used direct-to-metal, WB epoxy primers also exhibited good mechanical and adhesion properties that benefited the overall anticorrosion performances.Note de contenu : - Part I : Waterborne (WB) Zn-rich primer study

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : A novel emulsion polymerization technique is described to produce core-shell latex particles comprising poly(vinyl acetate) cores inside vinyl-acrylic shells. In a variation, acrylic shells can be produced surrounding poly(vinyl acetate) or vinyl acrylic cores. The latexes can be produced at commercial solids levels, with controlled, monodisperse particle sizes. The coatings formed from such core-shell particles exhibit the properties expected of the shell polymers. Core monomers are less expensive than the shell monomers, resulting in significant savings in raw material costs. The technique described is an inverted core-shell process in which the second-stage polymer is engulfed by a previously formed first-stage material. In coatings formulations the less expensive second stage monomers are more hydrophilic than those used to make the first stage polymer. Nevertheless, an inverted core-shell morphology can be made thermodynamically stable by appropriate choices of copolymerizable surfactants in the first-stage copolymer and nonionic initiator for the second-stage polymer. The resulting anchoring groups stabilize the desired particle structure.

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Alkyd resins have proven themselves both from a cost and performance point of view over a wide range of coatings applications such as architectural finishes, industrial metal, and agricultural/ construction equipment. Since alkyd paints are solventborne, they contribute to our societal VOC emissions. Increasing concerns regarding ground level ozone and indoor air quality have spurred R&D investment to find alternative technologies or approaches directed at lowering VOC emissions without compromising performance. This has proven to be a major challenge for the industry as a whole. The key issue is reformulating solvent-borne paints to be as low as possible in VOC while still delivering—or surpassing—expected performance benchmarks. Note de contenu : - High solids alkyd systems

Polyphthalazinone éther nitrile cétones
Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Poly(phthalazinone ether nitrile ketone)s (PPENK) modified with NaOH was studied in order to find a hydrophilic resin applied in heat-resistant waterborne coatings. The properties ofhydrolyzates, HPPENKa (0.5 h), HPPENKb (1.5 h) and HPPENKc (3.5 h), were measured by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), contact angle (water) and solubility. The structures ofhydrolyzates were confirmed by FT IR and 1H-NMR. The results indicated that the nitrile groups conversion ratio and Ts of hydrolyzates increased whereas the weight loss ratio of HPPENK decreased as hydrolysis time was prolonged. As expected, the hydrophilicity of HPPENK was improved greatly, e.g. when CN conversion ratio was 93.82%, the water contact angles was decreased from 75. 3° of PPENK to 54. 4° of HPPENK. By studying the effect of the different reaction co-solvents, reaction temperature and NaOH concentration on hydrolysis, the optimal synthetic technology could be concluded that it is of 6 N NaOH solution and DMAc as cosolvent at 120°C. Aqueous dispersions based on three modified resins were prepared and their storable stability was in the following order: HPPENKc >HPPENKb >HPPENKa. Especially, the HPPENKc dispersion was not found deposition more than 30 days and played good film-forming property. Cured film properties of HPPENKc as follows: pencil rigidity (6 H), thermal impact resistance (300°C, 24 h), adhesion (grade 1). Curing agents were applied in dispersion, such as Hexamethoxymethyl melamine(HMMM), epichlorohydrin (ECH), triethanol amine, glycerol, etc, among them, HMMM and ECH played excellent curing property. The cooperating emulsification of Span and Tween could improve stability of HPPENK dispersion. Note de contenu : - Structural characterization
