摘要

By establishing different formulations ranging from the type of pigment, pigment and filler proportions, pigment and filler purity grade (industrial, reactive, and technical), additives used and their proportions, and type of resin, various properties can be achieved depending on the desired final application. The objective is to explore and optimize pigment purity and formulation parameters to improve reflective properties. Each coating sample is then put to test in a UV–VIS spectrophotometer and a rheometer, where reflectance and viscosity values for each formulation are measured against benchmarks. Moreover, exposure to UV should be done for age testing, predicting longevity, and assessing the ability to retain color. As the first results show 93% reflectance with industrial-grade pigments, efforts for purity and further formulation exploration will be made. Continued optimization and exploration of high-purity pigments and formulation parameters are underway to further improve these values.
