Environmental testing was done on the cured alkyd emulsion paints, which included the OME-based corrosion inhibitor and a traditional anticorrosive pigment typically used for alkyd emulsion paints, over cold rolled steel (CRS) for 1000+hr in a 5% NaCI salt fog chamber. Adhesion of the cured paint films to the CRS substrate mas tested using direct and reverse impact testing and crosshatch adhesion. Both the environmental and adhesion test results indicated that there were significant improvements in the performance of the cured alkyd emulsion paints that had incorporated the OME corrosion inhibitor when used in conjunction with a traditional anticorrosive pigment. Improvements were also seen when using the organometallic ester corrosion inhibitor alone when directly compared to an alkyd emulsion paint that used a traditional anticorrosive pigment. The improved performance of the alkyd emulsion paint, when using an organometallic ester-based corrosion inhibitor, would allow the alkyd emulsion paints to equal that obtained when using solvent-based alkyd paints, thereby reducing the reliance on solvent-based paints for light industrial applications.

Other film. The introduction and development of TIO, throughoutthe 20th century enabled the production of
high-quality and safe paints for both interior and exterior use. However, the manufacturing processes of TiO2 are relatively expensive, and so this pigment is often the most expensive raw material used in emulsion paints. Many techniques andadditives has been developed over the years to help improve the utilization of TiO2 and thus recduce the amount used, while rnairitaining paint performance properties. There has been contintious effort to replace part of the TiO2 with fine particle site extenders in paint formulations. A detailed study has been undertaken to replace pigment by various percentages of calcined clays ; kaolin, PCC (precipitated calcium carbonate), Calcium aluminium silicate in to latex paint formulations. Properties such as thixotropie hiding power, light fastness, film brightness, scrub resistance, and weather resistance have been deterrnined to establish the optimum use of these extenders in the paint formulation.Note de contenu : - INTRODUCTION : Sulfate process - Chloride process

SiliceLa silice est la forme naturelle du dioxyde de silicium (SiO2) qui entre dans la composition de nombreux minéraux.
La silice existe à l'état libre sous différentes formes cristallines ou amorphes et à l'état combiné dans les silicates, les groupes SiO2 étant alors liés à d'autres atomes (Al : Aluminium, Fe : Fer, Mg : Magnésium, Ca : Calcium, Na : Sodium, K : Potassium...).
Les silicates sont les constituants principaux du manteau et de l'écorce terrestre. La silice libre est également très abondante dans la nature, sous forme de quartz, de calcédoine et de terre de diatomée. La silice représente 60,6 % de la masse de la croûte terrestre continentale.
Transparence (optique)Index. décimale : 667.9 Revêtements et enduits Résumé : The authors studied the use of Neuburg Siliceous Earth, as a functional filler for a waterborne two-component epoxy clear coat to achieve transparency and colour neutrality.
Anti-corrosion paints with sufficient protection properties can only be prepared with help of anti-corrosion pigments. When working with such pigments, however, an application as clear coats is not possible, as the refractive indice of the binder and the pigments are very different.
The fine sized Neuburg Siliceous Earth, on the other hand, is characterised by a refractive index close to that of the binder, which makes the filler in the coating appear transparent. As earlier anti-corrosion studies found, Neuburg Siliceous Earth as a functional filler is able to decidedly improved the corrosion protection properties becaus of its unique mineralogical composition.
The objective of this study was to meet the following requirement profile of the clear coat by using NeuBurg Siliceous Earth :
- Sufficient flexility and excellent adhesion on various substrates
- Good transparency
- No milky blushing of the clear coat after exposure to humidity
- Improved anti-corrosion properties.Note de contenu : - EXPERIMENTAL : Base formulation - Fillers used and characteristics - Formulation variations - Adjustment of application viscosity - Batch preparation, application and drying - Test methods colour values - Gloss - Pendulum hardness (Koenig) - Flexibility (Cupping test) - Adhesion (Cross Cut test 1mm) - Humidity test - Salt spray test

Conventional, mostly low-gloss interior emulsion paints often have the disadvantage of having insufficient resistance to staining, since liquid stains are easily absorbed into the surface due to the high and often supercritical pigment volume concentration and are, therefore, difficult to remove.
As a result, reduced liquid and stain absorbency in the coating is a desirable quality for cleanable paints. This can be achieved by setting a suitably subcritical pigment volume concentration, which enables more homogeneous film formation and sealed, less absorbent coating films. In addition, the sensitivity to staining can be reduced by using hydrophobic or oleophobic additive components in the formulation.Note de contenu : - EXPERIMENTAL : Basic formulation and variations - Preparation, application, and testing

Although complete eradication of corrosion is impossible, significant reductionin the corrosion rate can be achieved using various corrosion mitigation techniques, most notably using protective polymeric coatings. In this regard, the eco-friendly properties of waterborne paints have been attracting widespread attention in recent years due to the promulgation of lower allowable volatile organic compound content. However, these coatings are prone to increased penetration of moisture and corrosive species. To improve the protective properties of the coating we incorporated two non-toxic organic corrosion additives into a waterborne acrylic paint formulation and evaluated their anticorrosion properties using a combination of electrochemical tests, microscopy, and spectroscopic techniques.
