Abstract
Barium metaborate as a new less toxic anti‐corrosive pigment was tested for protection against corrosion in an atmospheric exposure testing station set in Egypt on Alexandria seashore. Seventy paints were prepared, based on six grades of laboratory prepared barium metaborate pigments. The paints could be classified into three groups according to the type of the binder; each group comprises seven subgroups according to the pigment grade used. The paints were tested first in the laboratory and then in actual environment. Commercial barium metaborate (Busan 11‐M1) based paints were prepared and used as a blank. High corrosion protection properties are obtained for up to nine years exposure. Results showed that mixing barium metaborate pigments with neutral binder gave better results than mixing them with acidic binder. Laboratory prepared pigments gave better results than the commercial one. It was also found that corrosion protection of these pigments increases with the increase of pigment modification.

Abstract
Summary The present work aims to study the inhibition mechanism of barium metaborate pigments. Six grades of barium metaborate pigments were prepared in the Laboratory of Polymers and Pigments, National Research Centre of Cairo, Egypt. The methods of preparation modification and evaluation is the main subject of a recent article. The pigments were incorporated, with other ingredients, into formulations, and the electrode potential, electrical resistance, water uptake and weight loss measurements were taken. Formulations based on a commercial pigment supplied by an international company were prepared and used as blanks.

Abstract
Different methods have been carried out to prepare barium metaborate pigments and to find out the suitable method of preparation taking into account ease of industrial application and the yield of the product. The properties of the prepared pigments were tested and compared with those of the commercial pigment. The solubility of the prepared pigment was found to be high and needed to be decreased. Many different methods of treatment were used and six grades of barium metaborate pigment were obtained. It was found that the addition of silicate to the prepared pigments has decreased their solubilities.

Abstract
Spot test methods were used for the qualitatative detection of the presence of Cu, lead and tin compounds in the antifouling paints leachates. Laboratory prepared antifouling paints were used as a guidance for the detection of these compounds. The methods were applied for commercial antifouling paints and gave promising results.

Abstract
Seventy paints were prepared, based on six grades of laboratory prepared barium metaborate pigments. The paints could be classified into three groups according to the type of the binder; each group comprises seven sub‐groups. The paints were tested first in the laboratory and then in actual environment (above and under sea water). Commercial barium metaborate (Busan 11‐M1) based‐paints were prepared and used as a blank.

Abstract
Introduction The application of organic coatings is the most extensive way of protecting metal products from corrosion. Developments of organic coatings and their applications are subject to the effects of many factors at present. The most important among these factors are ecological requirements aimed at the protection of the living and working environments, and the lack of raw materials and energy.

Abstract
Introduction Over the last few years there have been several trials to replace inorganic corrosion inhibitors, which in organic coatings are pigments, with materials which are, in principle, organic corrosion inhibitors. This coincides primarily with the toxic properties of the anti‐corrosive pigments employed and also with the scarcity of raw materials for their production.
