While the transition from solvent-based paints to water-based paints is an obvious and undoubtedly necessary topic,the choice of bio-based raw materials for water-based paints and replacing the existing fossil-based raw materials raises some concerns and many doubts.Renewable raw materials constitute a fairly substantial portfolio on the market.These are often raw materials in which fossil-based ingredients have been replaced with 100% bio ingredients.They are dispersion binders,additives such as defoamers,thickeners,as well as additives aspiring to be coalescents.In the laboratory of the research center for raw materials for water-thinnable paints”Spektrochem",tests of the effectiveness of a promising linear ester additive,100% based on renewable resources,were carried out in latex paint formulations.This additive is a newly developed auxiliary agent,which was tested in our laboratory for its manufacturer already at the R&D stage in order to optimize its effectiveness in formulations.This additive is hereafter labeled”Bio-based”and does not contain alkylphenol ethoxylate(APEO),biocides,formaldehyde releasers,VOCs or nonylphenol ethoxylates(NPE).
