Synergistic contribution of bio-based additives in wood paint
The work aims to reveal the synergistic behavior of two bio-based additives on the durability and protective behavior of a bio-based wood paint. The powder extract form spirulina was introduced as a natural pigment, while carnauba wax was used as a multifunctional filler. The impact of the two additives on the morphology of the coatings was investigated by scanning electron microscopy observations, while their role on the durability of the paint was assessed by exposing the samples to UV-B radiation and continuous thermal shocks.
As the reseachers point out, their work demonstrates the interesting synergy of spirulina and wax, able to provide an intense colouring and certain aesthetic features to the paint, to improve the water-repellent properties of the surface and to increase the abrasion resistance of the composite layer.
The study has been published in Progress in Organic Coatings, Volume 182, September 2023.
