prevents scaling during low-tension annealing process of steel components

In plant engineering, large welded structures must undergo heat treatment for stress relief.

This process leads to the formation of scales that must be removed by way of a complex process prior to any subsequent coating. s.

The new OSTRO-Thermol-Anti scaling Lacquer prevents the formation of scales. Thanks to its good adhesion, it can be used as a primer for the subsequent coatings.

Special features

The formation of the scale layer, which must be removed in a material- and time-consuming manner after the heat treatment, is prevented. This helps to save energy and resources.

OSTRO-Thermol-Anti scaling lacquer can also be used as a temporary anti-corrosion lacquer for transport purposes. We recommend recoating the components after approximately two weeks. Prior grinding is not necessary.
