The research conducted modified this process by replacing both the HSF technology with HSD technology and substitution with a more compatible organoclay. The modified organoclay exhibited the intercalation of cationic surfactant between the clay layers and thus, changed the surface properties from highly hydrophilic to increasingly hydrophobic. In addition, modification of the swelling clay with cationic surfactant results in an increase in the basal or interlayer spacing of the layer and exposure of new sorption sites of clay. This modification allows a lower viscosity and better dispersion with the moderately polar solvent system used in the formulation. The viscosity vs time results additionally illustrated that although the HSD system produced FOG particles larger than those of the HSF system and used less solvant over time, the HSF system produced CSAP that was more viscous and the smaller FOG particle size caused electrostatic tension in the paint suspension ie syneresis. The larger FOG particle size from the HSD system essentially contributed to paint stability. The improved CSAP manufacturing process achieved a substantial lower volume of solvent, which can also be recycled. Further research includes the application of solid-state NMR to further analyse the complexity of these organoclays in determining solubility limitations.

A guide for MEKO compliance arid 'future- proofing' alkyds / Allison Musto in SURFACE COATINGS INTERNATIONAL, Vol. 104.4 (07-08/2021)  

[article]  inSURFACE COATINGS INTERNATIONAL > Vol. 104.4 (07-08/2021) . - p. 278-279 Titre : A guide for MEKO compliance arid 'future- proofing' alkyds Type de document : texte imprimé Auteurs : Allison Musto, Auteur Année de publication : 2021 Article en page(s) : p. 278-279 Langues : Anglais (eng) Catégories : Agents anti-peau Cobalt Méthyléthylcétone oxime La méthyléthylcétone oxime est le composé organique de formule C 2 H 5 C(NOH)CH 3 . Ce liquide incolore est le dérivé oxime de la méthyléthylcétone . MEKO, comme on l'appelle dans l'industrie de la peinture, est utilisé pour supprimer le "pelling" des peintures : la formation d'une peau sur la peinture avant son utilisation. Il est particulièrement utilisé dans les peintures alkydes . MEKO fonctionne en liant les agents siccatifs , les sels métalliques qui catalysent la réticulation oxydante des huiles siccatives. Une fois la peinture appliquée sur une surface, MEKO s'évapore, permettant ainsi au processus de séchage de se poursuivre. D'autres agents anti-peau ont été utilisés, notamment des antioxydants à base de phénol , mais ceux-ci ont tendance à jaunir la peinture. Le butanone oxime est également utilisé dans certains types de silicones RTV.

As the industry increases sustainability standards for paint formulations, a hurdle for alkyd coatings remains in the raw materials required to formulate a paint, namely cobalt catalysts and methyl ethyl ketoxime (MEKO) anti-skinning agents. These two materials face increasing regulatory changes, which will simultaneously increase the burden on formulators developing label-free paint. MEKO's toxicity makes it challenging for formulators to meet safe exposure limits due to its volatility and additionally, MEKO and cobalt have been classified as carcinogens. In this paper, we discuss non-toxic alternatives to both materials, focusing on the path to reformulation with data demonstrating the performance benefits of Borchers'cobalt and MEKO alternatives. Background on alkyd coatings : Alkyd-based coatings dry via autoxidation when oxygen reacts with points of unsaturation based on fatty acids in the resin.This process can be prolonged if unaided, so cobalt-based catalysts are utilised as oxidative catalysts to speed the curing of alkyd resins. Since cobalt catalysts are reactive to oxygen, an anti-skinning agent such as MEKO is often required to prevent the paint surface from forming a film (called 'skin').Therefore, many alkyd-based paint formulations are dependent on cobalt for adequate curing and on MEKO for storage stability.

High performance alkyd paints based on platy kaolin for corrosion protection of steel / Hassan Salah Aly Emira in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 10, N° 2 (03/2013)

Langues : Américain (ame) Catégories : Anticorrosion Carbone Charges (matériaux) Kaolin Métaux -- Revêtements protecteurs Pigments Polyalkydes Revêtements Traitement thermique Index. décimale : 667.9 Revêtements et enduits Résumé : Calcination of kaolin presents an easy route to obtain high performance and eco-friendly anticorrosive filler. The objective of the present work was to prepare a new ecologically friendly inorganic filler, based on thermal treatment of kaolin to be used as an anticorrosive. This work studied the corrosion protection of medium oil-modified alkyd paints based on thermally treated kaolin at different temperatures. Paints were formulated with different pigment volume concentrations (PVCs) and critical pigment volume concentrations (CPVCs). The prepared paints were formulated with increasing content of kaolin, with PVC ranging from 10 to 30%. The physical and chemical properties of kaolin were evaluated at different temperatures. Particle shapes of thermally treated kaolin were characterized using scanning electron microscopy. The physico-mechanical properties of dry films, water vapor transmission and their corrosion properties using accelerated laboratory corrosion test were tested. The thermal treatment of kaolin enhanced both the oil absorption and the alkalinity. This led to alkyd results in saponification and consequently passivation of the substrate. Good wetting with alkyd resin gave homogeneous films without defects which resisted water and oxygen permeation and protected steel against corrosion. The results revealed that thermally treated kaolin at 400°C was the best at protecting steel substrates for all PVCs.
