We pursue a sustainable approach in the development and selection of active ingredients – effective, high-quality and innovative. With more than 40 years of experience, our current knowledge and expertise and state-of-the-art scientific research methods, the biogenic binder Replebin\u00ae, which consists of plant alcohol esters with organic acids, was created in 2015. The raw materials required for this come, for example, from the residues of maize and wheat plants that cannot be used in the food chain. The starch still present in these components is the basis for our raw materials for Replebin\u00ae production. The modern binder is used in almost all AURO paints and plasters; it is an essential component and guarantees the excellent quality and sustainability of our products. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

This could be an approach to develop new types of flame-retardant paints or to develop systems that use suitable technologies to do without synthetic preservatives in the future. We work together with renowned research institutes on these projects and have even taken on a project this year that is funded by the European Union (Horizon 2020).

Graphene comes from the mineral graphite, which has been used for centuries and is best known for its use in pencils, for example.

The issue of microplastics is playing an increasingly important role in environmental pollution. However, many pollutant influences are not immediately noticeable or recognizable. A Norwegian study* even found that around 17% of the microplastics produced worldwide come from the abrasion of paints and varnishes used outdoors, which are composed of plastic-based binders such as pure acrylate, silicone resins or styrene acrylate. As a result, several tons of these barely filterable plastic particles are released into the environment every year, some of which end up in our bodies. Despite its performance spectrum and thanks to its entirely mineral character, Ecolith<\/strong> is completely free of microplastics<\/strong> or other environmentally harmful ingredients. <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Which properties of the colors are improved by this? <\/a>\n\t\t\t\t\t<\/div>\n\n\t\t\t\t\t

The use of graphene in lime paints makes it possible to offer this product class in unprecedented quality. The addition of mineral graphene with an immensely high surface area turns the otherwise brittle lime paint into a highly flexible paint. This enables us to achieve a wet abrasion class of 1 and even allow it to be used as a fa\u00e7ade paint, which is otherwise not possible with lime paints. <\/strong><\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Graphene is based on graphite and forms very thin but extremely large areas that are very flexible. If these are homogeneously distributed in the lime paint, this large-area network stabilizes the lime and the fillers in the paint by enclosing them. It is also virtually chemically inert and able to have a water-repellent effect in the coating. The high flexibility and hydrophobicity give the new Ecolith Exterior and Ecolith Interior their special properties. <\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

What challenges did you have to overcome in developing the new technology? <\/a>\n\t\t\t\t\t<\/div>\n\n\t\t\t\t\t

The most difficult process during production is due to the special features of the new products described above. Very large particles in terms of surface area, which also have a very high hydrophobicity, must be dispersed homogeneously in an aqueous medium so that they do not separate again in the finished product and the effect is therefore permanent. <\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

So of course we have to ask about the origin of the graphene. How do you ensure that it comes from sustainable sources? <\/a>\n\t\t\t\t\t<\/div>\n\n\t\t\t\t\t

There are several manufacturing processes for the production of graphene, ranging from a pure laboratory process to production scale. Consistent product quality is important for the manufacturing process in order to have the dispersion process described above under control in the long term. To ensure sustainability, the graphene for AURO products is obtained from graphite. The manufacturing process is essentially a pyrolysis-based process. <\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Why in such systems in particular and are you also planning to upgrade other coating systems with graphene? <\/a>\n\t\t\t\t\t<\/div>\n\n\t\t\t\t\t

The use of graphene raises the mineral lime products Ecolith to a new, previously unattainable technical level. As our customers are generally very focused on mineral paints, it made sense to use graphene technology to make these products usable for exterior or highly stressful interior applications. At the moment, we are also investigating the use of graphene to positively influence other products. We are currently considering testing effects on paints, varnishes and\/or wall paints. However, the challenge here is also to be able to establish the graphene in the formulations in a stable manner. Compared to pure lime paints, however, these products are much more complex in their composition, which does not make the efforts any easier. <\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t
