Functional Olive Pit Powders: The Role of the Bio-Based Filler in Reducing the Water Uptake Phenomena of the Waterborne Paint

In this study, olive pit powders were added to a polyurethane-acrylate paint for examining the impact of two alternative functionalization processes in increasing filler hydrophobicity an effort increase durability paint. order look into potential changes morphology and appearance owing surface conversion treatments bio-based additives, coatings examined using electron microscopy colorimetric tests. The coating’s resilience hydrophobic/hydrophilic role fillers evaluated by salt spray chamber exposure, contact angle measurements, liquid resistance, UV-B electrochemical impedance spectroscopy which highlighted reduction water absorption inclination made lignocellulose due silane wax functionalization. This study demonstrated that filler, if properly functionalized, can actually be implemented as multifunctional pigment waterborne paints, giving specific aesthetic characteristics, but also improving barrier performance polymeric matrix composite coating.
