In order to maximise the longevity of coatings under such conditions, coating manufacturers have to develop robust formulations containing algicidal and fungicidal actives. Evaluation of resistance to biological defacement on a given coating is achieved by a combination of accelerated laboratory tests and prolonged field exposure evaluations in selected locations to account for regional climatic conditions and microflora. This paper covers results of field evaluations. Note de contenu : - FIGURES : Germany : commercial silicate exterior paint ; orientation : 60°, north-east facing ; duration : 2 1/2 years - 2.

How do we protect paints and coatings from microbial contamination in the future ? / Emmanuelle Yvon in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 208, N° 4638 (02/2018)

For those who want to be both ecolabel compliant and avoid the H317 label under the CLP legislation, the choice of actives will be severely limited and the cost to treat will increase. Looking at other active substances that are still under evaluation in the BPR review programme, the choice of biocidal ingredients to replace MIT will be even trickier considering the future of most actives is still uncertain. Dow has some novel actives, such as DTBMA or MBIT that could bring innovative sustainable solutions when used in combination with other actives.

Both the one- and two-layer systems offer combinations that can meet the sectors' needs and specification for performance, corrosion protection and gloss and colour retention. However, as these markets becomes more demanding, coatings manufacturers like Axalta must work ever more closely with their customers to create specific solutions that address both practical and financial demands by continually developing high-quality, cost-effective technologies.

An easy, tried-and-true method to ensure quality in coatings / Jeffrey B. Carr in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 208, N° 4638 (02/2018)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 208, N° 4638 (02/2018) . - p. 50-54 Titre : An easy, tried-and-true method to ensure quality in coatings Type de document : texte imprimé Auteurs : Jeffrey B. Carr, Auteur Année de publication : 2018 Article en page(s) : p. 50-54 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Attapulgite Argile alumino-magnésienne fibreuse. Charges (matériaux) Epaississants Revêtements -- Additifs:Peinture -- Additifs Index. décimale : 667.9 Revêtements et enduits Résumé : Coatings are complex composites designed to have a stable shelf-life, apply easily to a substrate and provide lasting durability in varied environments. These performance criteria require disparate materials to be finely dispersed and work cohesively, which presents a major challenge as composites can be unstable and ultimately fail at points of inconsistency. To address this, the first thing a new paint chemist learns is that wetting agents are mandatory in allowing mineral fillers to disperse properly. Without them, these inorganic particles generally reject their organic media, agglomerate and settle out. It would be imprudent to forgo wetting agents. Another well-known, tried-and-true technique to stabilise composites and improve their uniformity is to use high-quality, gel-grade attapulgite mineral products. They have been common in paint applications for several decades as thixotropic thickeners for low-shear flow and levelling, sag resistance and other rheology benefits. However, a seemingly forgotten higher value is their function as excellent stabilisers due to their unique colloidal lathe-shaped particles forming a lattice structure. This keeps liquids and particles more evenly dispersed and suspended, generating important benefits well beyond rheological properties. This article gives a brief history of attapulgite, a description of its mechanism that sets it apart from other thixotropic thickeners and stabilisers, and discusses its performance benefits in coatings. Note de contenu : - Chemistry and morphology - How attapulgite works - Particle network and performance - Features and performance - Exceptional performance and economies - Uniform suspensions - In-can stability - Fig. 1. Crude attapulgite mined by Active Minerals International LLC - Fig. 2. Attapulgite lattice network when dispersed in a liquid - Fig. 3. Comparison of shear stress and viscosity at various shear rates for Min-U-Gel 400 attapulgite and HEC in water. The loading levels of both materials have been exaggerated to produce comparable rheological values. In coatings, where the attapulgite network interacts with particulate solids, the dosage level of Min-U-Gel 400 is similar to HEC.
