Impregnation of porous structures in the foundry industry

In the course of the casting process, micropores may form which render the casting unusable. With Dichtol impregnation from DIAMANT, however, the cast part regains its functionality and is also upgraded.

Regardless of the material or process, the application is completely uncomplicated and takes place at room temperature without vacuum or pressure. Dichtol is therefore the ideal solution when it comes to sealing, infiltrating or impregnating porous structures and layers.

Thanks to the capillary effect, the polymer system penetrates quickly and deeply into the parts to be treated. After curing, the treated structures are filled with a polymer and permanently protected. Areas of application include the sealing of cast parts in the foundry industry.

The variants Dichtol WFT Standard #1532 (for sealing porosities of approx. 0-0.1mm) and Dichtol Makro #1546 (for sealing porosities of approx. 0.1-0.5mm) have long proven themselves in the industry, e.g. in the case of locally known leaks, the punctual impregnation ensures an efficient use of material. The direct application on site eliminates the need for long waiting and delivery times.

Most Dichtol variants are colourless, so it may not always be possible to tell which areas have already been treated and which have not. For such cases, we have developed the Dichtol WFT Blue #2541 and Dichtol Black # 1903 variants to remedy such problems. With the blue and black color variants, as with the standard variant, the smallest pores (0-0.1 mm) can be closed and a high level of pressure tightness is guaranteed, even with difficult object structures. All our variants can of course be painted over after curing.

We also offer a fluorescent version for very special applications.

Here are just some of the advantages of our Dichtol:

Efficient material consumption at around 100ml / m²
Wide range of applications by dipping, brushing and injecting
Temporary corrosion protection after curing
Individual impregnation (of large components)
Selective series impregnation
No complicated vacuum impregnation necessary
