Introducing a Novel Application of Bio-Based Fillers Based on Rice Bran Wax Infused with Green Tea: Transitioning from a Cosmetic Additive to a Multifunctional Pigment for Wood Paints
Source abstract
Abstract
This study aims to assess the functionality of a bio-derived additive, comprising rice bran wax infused with green tea, as an environmentally sustainable and adaptable pigment for wood coatings. Additionally, the effectiveness of the bio-based additive, in conjunction with a specialized UV absorber to enhance color consistency under harsh conditions, was examined. Aesthetic impact was analyzed through evaluations of color, gloss, and surface roughness. Moreover, the stability of the wax-based powder in aggressive environments was characterized by subjecting samples to UV-B and climatic chamber exposure. The barrier properties of the additive were investigated using a water uptake test and contact angle measurements, while liquid resistance tests were conducted to gauge its efficacy. Lastly, the protective role of the bio-based additive was analyzed through scrub tests and surface analysis using scanning electron microscopy. Findings underscored the versatility of the green additive as a multifunctional pigment, offering not only color enhancement but also robust protective capabilities. Its unique combination of color, mattifying effect, barrier enhancement, and protective function position it as an attractive bio-based additive for wood coatings with functional applications.
