Comparison of Properties of External Color Emulsion Paint in Thailand

Abstract

This article presents a comparison of the weather resistance qualities and solar radiation reflection of emulsion paint for external applications in Thailand. By comparing the collected catalogs and academic papers on industrial product standards for each paint model, the various color differences were established as a foundation for further testing.

Then the interview with people related to paint was conducted together with the visits to paint the wholesale and retail areas. The results revealed that each brand has different grades of paint. Paint can be divided into four categories: economy, standard, premium, and ultra-premium. These categories indicate the quality of paint . This is because paint grades are classified based on their useful life: economy grade lasts 1-3 years, standard grade 5-7 years, premium grade 8-10 years, and ultra-premium grade 11-15 years. Currently, there are several paint brands. This study selected five major brands with the largest market share: TOA Paint, Nippon Paint, Dulux, Beyer, and Jotun Thai. By selecting their number and best-selling paints of each grade to compare their industrial product standards, color qualities, and technical information, The comparison results show that useful life is prioritized over performance in paints grading. Many industrial standards only indicate how long a particular paint model may pass the test, therefore they don't identify better colors. When comparing technical facts paints selection cannot be solely based on the theoretical amount of space because the amount of space obtained and the price are inconsistent.
