Lignin depolymerized fractions
LIGNICOAT project will pave the way for the optimization of lignin depolymerization conditions related to their application in epoxy resins and coatings, as well as in polyester/alkyd resins.
Synthesis of lignin polyols (LPOs)
Aiming at mild reaction conditions and reduction of the oligomers formation, the synthesis process of LPOs will be explored under the LIGNICOAT project for the development of BioPU coatings.
Synthesis of bio-based alkyd
The currently available bio-based alkyd binders are not economically competitive nor have the drying performance of fossil-based binders. LIGNICOAT targets to expand the bio-based binders market, taking advantage of the molecular structure of lignin, which would improve the drying performance, as well as its price competitiveness.
Synthesis of bio-based Polyurethane alkyd (PUA)
The use of lignin as a raw material for the production of bio-based polyurethane alkyd dispersion will be examined under LIGNICOAT project. Due to their molecular structure, lignin polyols or polyacids would improve the drying performance of the coating.
Synthesis of bio-based PUD
The use of lignin as a raw material for the production of bio-based PUD will be examined under LIGNICOAT project. Due to their molecular structure, lignin polyols or polyacids would improve the drying performance of the coating.
Formulation of bio-based epoxy resins
A new formulated bio-based and eco-sustainable epoxy resin and a related formulation for coatings application will be studied under LIGNICOAT project.
Currently the antiviral and antimicrobial features are achieved through the utilization of hazardous compounds. In LIGNICOAT, the use of new bio-molecules and enzymes will be examined.
Lignin based polyacids for polyester coatings
Lignin has been studied mainly as a polyol in coating applications, but not as polyacid due to the inherent lack of carboxylic functionalities. The development of lignin based polyacids for polyester coatings will be studied proposing a sustainable lower-cost alternative for synthetic polyacids.
The development of coatings including natural active compounds, responsible for the antimicrobial properties, designed to prevent the microbial adhesion to the surface, avoiding biofilm formation is of great novelty.
Low VOC coatings
LIGNICOAT will address the innovative potential of enzymes as bioadditives in coatings to create self-decontaminating surfaces that reduce the emission of hazardous VOCs.
LIGNICOAT proposes the use of lignin derivatives to substitute oil-based aromatic compounds currently present in coating formulation, to bring the benefit of improved sustainability, adhesion and anticorrosion.
LIGNICOAT propose the incorporation of phosphorous derivatives in the resins as a reactive approach which will promote fire proofing performance to the coatings, for wood and metal applications.
