What problem does our project solve?

Our project focused on exploring the possibilities and methods of producing high-quality, eco-friendly water-based primer system pigmented with zinc, although with a lower zinc content in the final product. The project goal was achieved through the selection and modification of the polymer matrix composition and the addition of agents with exceptional stability and barrier, protective, and mechanically reinforcing properties to the coatings. A water-dilutable epoxy resin was used in the project, containing a reduced amount of modified zinc pigments compared to traditional high-zinc anti-corrosion primers. Despite the lower zinc content in the coating, the developed primers can match high-zinc primers in terms of protective properties, while also meeting environmental regulations.

Who will benefit from the project's results?

The results of the EcoWaterZinc project can be used by entities from various groups and sectors.

For example, in the construction sector, manufacturers of coatings for protecting metal structures can use the technology to manufacture their products in a sustainable, environmentally beneficial and more economically viable way. It is also less harmful to the health of workers in companies involved in metal protection.

Such products also positively affect society, which will benefit from a cleaner environment due to reduced metal contamination.

What was the biggest challenge for us in implementing the project?

The biggest challenge was stabilising the product in terms of storage. Water-dilutable, metal-pigmented paints can have a tendency to react with water. Thanks to innovative formulation and auxiliary agents, this problem was successfully addressed.
