For the last few decades, there has been significant interest among coating researchers around the world to design water-based polyurethane dispersions (PUDs) that can be cured at ambient conditions. Polyurethanes are the most versatile polymers, exhaustive studies have been reported and more details of all aspects of their properties and uses are given. Vegetable oil-based polyurethanes are used in various fields from coatings to elastomers including smart biomaterials. This paper comprises overview in recent developments on the preparation of biobased polyols from plant oils, covering from the general epoxidation as welI as to high light the properties of polyurethanes obtained from them.

Langues : Anglais (eng) Catégories : Antimicrobiens Revêtements -- Additifs:Peinture -- Additifs Revêtements en bâtiment:Peinture en bâtiment Index. décimale : 667.9 Revêtements et enduits Résumé : Biocides and dry-film Preservatives are an integral part of the Architectural Coatings landscape, and assume a greater significance in India, given the large share of this segment, the tropical climate as also the qualitative increase in coatings and the need for their longer life.There are varying perspectives and theories on the technology and regulations surrounding this. We, at Paintindia, intend to bring to the industry varied and diverse views from credible sources, and allow the industry to form its own opinions and judgements on the same. While Paintindia will always filter and verify the sources and content, the inherently controversial and subjective nature of the subject means that there will always be contrarian views on the same.

[article]  Accompagne High performance pigments (HPP) / Tipanna Melkeri in PAINTINDIA, Vol. LXVIII, N° 3 (03/2018) inPAINTINDIA > Vol. LXVIII, N° 4 (04/2018) . - p. 69-71 Titre : Copper phthalocyanine alpha blue (15.0, 15.1 and 15.2) : Copper phthalocyanine (CPC pigment : Part 3) Type de document : texte imprimé Auteurs : Tipanna Melkeri, Auteur Année de publication : 2018 Article en page(s) : p. 69-71 Langues : Anglais (eng) Catégories : Phtalocyanine de cuivre Pigments organiques Index. décimale : 667.2 Colorants et pigments Résumé : Copper phthalocyanine pigment (CuPC) is one of the most stable pigments towards light, temperature and chemicals. It exists in different crystal modifications. Crystal modifications α, and β have gained considerable commercial importance in industry . Crystal modification "α" is called pigment blue 15.0. It is obtained by acid pasting of crude CuPC. Pigment blue 15.0 is only stable upto 170°C. It shows very poor solvent resistant and also limited temperature stability. PB15.1 is improved version of PB15.0 with higher thermal stability but poor solvent stability. High thermal stability is achieved by surface modification of PB15.0 with suitable additive. Because high thermal stability it is used in all types of plastics and rubbers. PB15.2 is improved version of 15.1 with high solvent and thermal stability. All grades of pigment alpha blue are manufactured by process called acid pasting. Pigment alpha blue is used in various applications such as plastics, rubbers, ceramics, cements, inks, paints and cosmetics. Due to its high thermal stability, it is used in high performance coatings and engineering plastics.

High performance emulsion coatings / M. Veeramani in PAINTINDIA, Vol. LXVIII, N° 4 (04/2018)  

[article]  inPAINTINDIA > Vol. LXVIII, N° 4 (04/2018) . - p. 90-94 Titre : High performance emulsion coatings Type de document : texte imprimé Auteurs : M. Veeramani, Auteur Année de publication : 2018 Article en page(s) : p. 90-94 Langues : Anglais (eng) Catégories : Applications extérieures Formulation (Génie chimique) Polyacryliques Revêtements en phase aqueuse:Peinture en phase aqueuse Index. décimale : 667.6 Peintures Résumé : Now let us turn our attention to the formulation of High Performance Exterior Emulsion Coatings. We must bear in mind that this paint should not only retain the pigment for a longer duration without fading but also should withstand the extreme weather conditions like temperature and excess rain. It is a challenge to the Formulator as he has to look into all the performance aspects of the coating with a minimum guaranteed life and formulation economy. He has to choose the additives carefully and also the type of pure acrylic emulsion that goes into the paint making, in order to ensure the minimum performance of the paint.

Acrylic metallic laquer for automotive and industrial use / Mukund Hulyalkar in PAINTINDIA, Vol. LXVIII, N° 4 (04/2018)  

[article]  inPAINTINDIA > Vol. LXVIII, N° 4 (04/2018) . - p. 98-100 Titre : Acrylic metallic laquer for automotive and industrial use : Thermo plastic acrylics resins Type de document : texte imprimé Auteurs : Mukund Hulyalkar, Auteur Année de publication : 2018 Article en page(s) : p. 98-100 Langues : Anglais (eng) Catégories : Automobiles -- Revêtements:Automobiles -- Peinture Formulation (Génie chimique) Peinture métallisée Polyacryliques Thermoplastiques Une matière thermoplastique désigne une matière qui se ramollit (parfois on observe une fusion franche) d'une façon répétée lorsqu'elle est chauffée au-dessus d'une certaine température, mais qui, au-dessous, redevient dure. Une telle matière conservera donc toujours de manière réversible sa thermoplasticité initiale. Cette qualité rend le matériau thermoplastique potentiellement recyclable (après broyage). Cela implique que la matière ramollie ne soit pas thermiquement dégradée et que les contraintes mécaniques de cisaillement introduites par un procédé de mise en forme ne modifient pas la structure moléculaire. Index. décimale : 667.6 Peintures Résumé : The use of Thermoplastic type of Acrylic Resin as a modifier for improving properties of the other resins has been demonstrated. The Acrylic Resin is used as a major Resin component in automotive type enamel.
