Processos de produção e avaliação do desempenho de tintas á base d’ água para decoração e sua questão ambiental

Abstract

The decorative paints account for 83.3% of the total volume of Brazilian production and 69.3% of sales, with a 1.9% increase in production volume from 2016 to 2017. However, due to the large variety of types of paint that the market offers, there are still many doubts among consumers in choosing the right product, which because of lack of knowledge often end up opting for the cost and not for the quality, compromising the finish and the durability of the painting. Currently the largest investment of the real estate paint industries are focused on this "new" segment that is "customer satisfaction and low cost", always seeking to improve its products tied to the minimum cost increment in its formulation. In this context, this work presents a bibliographic study that addresses the importance of decorative paints, presenting a little of the historical, current economic scenario that it represents, its chemical composition, highlighting the raw materials that constitute them as pigments, resins, solvents, additives , vehicles and their functions. In addition, it will describe the manufacturing process and how the disposal and treatment of the effluents and wastes generated during this production process is carried out, as well as the practices adopted in the industries in order to offer products that increasingly meet the environmental, contributing, at the same time, to economic and social development. Among the practices adopted in the paint industries, water-based paints are aimed at reducing the emission of volatile organic compounds (VOCs), which is a trend in the world due to its less harmful characteristics to the environment , maintaining similar quality to solvent-based paints (synthetic paints), which make them a great potential for expansion in Brazil, capable of meeting the most diverse consumer requirements in a wide range of applications.
