Evaluating the versatility of stainless steel flakes and magnetite powder as polyvalent additives for wood paints

The objective of this study is to evaluate how various fillers, specifically stainless steel flakes and magnetite powder, affect the visual attributes, durability and versatility of a water-based wood paint. To examine the influence of these two specific pigments on the overall look of the coatings, colorimetric measurements were carried out. The impact of these distinct fillers on the durability of the layers was assessed by subjecting the samples to xenon arc light exposure and cyclic thermal shocks, followed by colorimetric inspections and adhesion tests. Furthermore, the fillers’ impact on the coating’s ability to act as a barrier was assessed through liquid resistance and water uptake tests. Additionally, the Buchholz hardness indentation test and the Taber test were conducted to quantify how these functional additives affect the mechanical properties of the coatings, such as hardness and resistance to abrasion. Lastly, two specific tests revealed the fillers’ role in introducing unique electrical conductivity and magnetic attractive properties to the paint. In conclusion, this study underscores the intriguing influence of stainless steel flakes and magnetite powder, which not only impart vibrant colors and distinct visual characteristics to the paint but also maintain the coating’s protective barrier properties, enhance the mechanical properties of the composite layer, and introduce specific multifunctional features to the coating.
