Epoxy resins are widely used in coatings thanks to their excellent adhesion to materials and their durability. However, epoxy resins typically contain aromatic groups with strong absorption in the UV range. This makes epoxy structures vulnerable to UV degradation. The performance of one company’s stabilizers in a typical commercial epoxy resin with hardeners are tested and reviewed in this article.
Today, many coatings producers are increasingly focusing their production towards water-based coatings and are moving away from solvent-based formulations. This is to reduce the VOC content of their formulations, not only to make it friendlier for the end-user, but also to improve the sustainability impact on the environment by reducing their CO2 footprint.
Anti-foam products allow controlling the presence of unwanted foam in different processes, including the manufacture and application of paints. A new range of mineral oil-free anti-foams have been designed, which are not harmful to humans or the environment due to their low or no toxicity, and include enhanced bio-degradability of the raw materials.
Best practices when selecting rheological additives are discussed in this article. The article explains that properly prepared technical materials are the basis for a quick and efficient start of tests and drawing conclusions based on repeated case studies in specific paint manufacturer formulations.
As a stabilizer and secondary rheology modifier, colloidal MCC provided minimum viscosity to waterborne coating systems at low use level while significantly improving in-can shelf stability and color-tinting ability.
Graphene nanotubes introduced into a polyurethane coating facilitate an anti-dust effect on artificial leather car seats while preserving mechanical properties.
In recent years, a relatively new innovation added to the marine coatings technology toolbox has been shaking things up and gaining some serious traction in the maritime industry.
