Water-dispersion paints: classification and assortment

Abstract

Background. Assortment of water-dispersion paints (WDP) and coatings which is presented at the market and constantly updated determines the need for their classification. Production of WDP in Ukraine requires the development of approaches to formation of itsassortmentfor industrial enterprise in order to maximally meet the Ukrainian consumers’ need that determines the relevance of this article.
The aim of the article is to develop an improved classification and approaches to formation of WDP assortmentfor industrial enterprise.
Materials and methods. The research object is the developed assortment of WDP for industrial enterpriseand the operational properties of applied coatings.
The researchers are carried out with application of general scientific and special methods of economic processes knowledge: analysis and synthesis, system approach, comparison and generalization.
Results. The provisions of the national standards DSTU EN 13300:2012 and DSTU EN 1062-1:2012 which are identical to European ones were the basis of improved WDP classification developed by us. The general classification of WDP is supplemented by such features and classification clusters as degree of filling, functional purpose, application, material of the surface to be painted, method of application.
Formation of the WDP assortment is carried out in order to maximally meet the consumers’ requirements. As the main approaches to the formation of the WDP assortment itwas proposed such ones that include consideration of compliance with the classification criteria: functional purpose (decoration, protection); application (for internal or external use); material of surface, for painting of which the WDP is assigned; operational load (high, medium and low); level of the coating operational properties (functional, aesthetic, protective, reliability etc.).
The following characteristics of the coating have been identified as the main criteria for assigning to a certain class of theoperational load degree: adhesion to the surface material, the tensile strength of the coating film, resistance to wet abrasion and others. Recommendations for the application of coatings with different operating loads, the consideration of which will allow consumers to correctly select WDP to meet their needs in obtaining coatings with the necessary properties have been developed.
Conclusion. Based on the results of the research and taking into account the developed approaches we have created an assortment which includes seven types of basic white WDP of different designated purpose and degree of operational load, which are recommended for industrial production at Ukrainian enterprises and application by consumers. Anecessary colour can be obtained by adding of pigment concentrates to the base WDP due to which the assortment of WDP and coatings can be expanded. The created WDP composition and the operational properties of the coatings will be highlighted in the following publications.
