The drastically increased energy prices challenge manufacturers of paints and varnishes to increase the efficiency of their production processes and lower energy consumption to ensure their competitiveness.

Compared to conventional technologies such as high-speed dissolvers (HSDs) or agitators, modern technologies achieve significant improvements: Depending on the application, the energy consumption can be lowered by up to 90%.

Find out about 3 of the most important levers with which producers of varnishes and paints can reduce their energy requirement, and learn how processes are implemented energy-efficiently with technologies from ystral, the mixing and dispersion technology specialist.

Shorten process times

Innovative mixing and dispersion technologies can significantly shorten process times with regard to the production of paints and varnishes compared to conventional solutions. As a result, this leads to a significantly reduced energy demand even with a higher output used, as energy is power multiplied by time.

By using process intensification and a realisation of intense processes outside of the vessel, ystral achieves significantly shorter process times in the production of paints and varnishes: For example, resins can be dissolved in a fiftieth of the previously required time, and the total production time can be decreased by more than 80%.

Minimise the use of a grinder

With conventional mixing technologies, powder particles are not fully wetted when induced into liquids, and agglomerates are generated as a result. The required fineness in the production of paints and varnishes can frequently only be achieved through subsequent grinding – this is a very time-consuming and energy-intensive process.

When using an inline disperser from ystral, powder particles are fully wetted and dispersed immediately one by one by means of dispersion under vacuum. Agglomerates cannot form in the first place during powder induction into liquids.

Subsequent grinding can be completely dispensed with for many applications. For products that require the grinding of particles, the grinding times are reduced significantly – for example, in the case of a black automotive top coat, from 30 hours to 16.5 hours.

Achieve reproducible results

When using conventional technologies, the product quality depends on numerous factors, and the dispersion results fluctuate greatly. For this reason, rework on the product has so far been common practice in the production of paints and varnishes – bringing with it a not insignificant energy demand. If there are faulty batches, this is also accompanied by costly disposal and preparation of materials.

Through constant process parameters and an immediate and complete breakdown of powdered raw materials, ystral achieves a consistent product quality. As the powders are not added to the open vessel from the top, but are absorbed into the dispersing zone under vacuum, the quality of the end product cannot be affected by operating errors. Reworking for final adjustment of the product is not necessary. The risk of faulty batches is minimal.
