Influence of TiO2 Nanocrystals on Alkyd Resin Paint Films to Protect Metals | Asian Journal of Chemi

Aims and Objectives: Nanomaterials technology is rapidly evolving these days, offering high economic efficiency to a variety of industries, including paint. The goal of this research is to see how paint characteristics change when TiO2 powder coating is replaced with nano TiO2 at various ratios.

Materials and Methods: The study used a typical alkyd paint mix and replaced the coating powder TiO2 with nano TiO2 to track the qualities of the paint film over time. The methods used to assess the qualities of the paint film are based on Vietnamese standards.

Results: The study results showed that TiO2 coating powder replaced by TiO2 nanomaterials has increased the properties of the paint film, improving the thickness, gloss, and durability of the paint film. Nano TiO2 increases from 0.5% to 24% by weight, the impact increased by about 11% (73 to 82 kg.cm), Glossy 60° increased by about 12%, Glossy 85° increased by about 12%, especially the durability of paint film over time increased nearly double. Nano TiO2 is a more expensive material than TiO2, so it should replace less than 4% by weight to increase the quality of the paint film, this ratio is changed according to the actual equipment requirements.

Conclusions: The higher the rate of replacing TiO2 materials with TiO2 nano, the better the properties of the paint film. Therefore, nano-material TiO2 is a good coating in alkyd resin for metal paint, it improves the properties of paint film better than TiO2 material.
