Maximum Dedusting of Powder Coatings Containing Titanium Dioxide

Regardless of whether the branch is the automotive industry, metal coatings or outer facades and furniture: powder coatings have manifold applications in industry. Around 60% of all powder coating recipes contain titanium dioxide (TiO₂). The maximum portion is about 30% and can be found above all in extremely bright shades of white. The European Commission is now demanding new limit values for titanium dioxide from 2021 onwards. With the TSP air classifier, Hosokawa Alpine presents a suitable solution for the effective dedusting of powder coatings that contain titanium dioxide.

The TSP air classifier was designed especially for challenging classifying tasks. The development phase focused on maximum precision of cut as well as aspects such as handling, safety, operation and installation costs.

The use and manufacturing of chemical products, including titanium dioxide, must conform with stringent registration, testing and approval procedures based on regulations and standards. These legal requirements ensure that these chemicals are not harmful to either health or environment when used in their intended applications.

In a proposed amendment, the European Commission has decided to classify certain products, among them titanium dioxide, which have at least 1% of particles and an aerodynamic diameter of ≤ 10 µm as possible carcinogenics (category 2) and to label end products with corresponding hazard statements. The transitional period until the new legislation is enacted expires on 1st October 2021.
