According to the abstracts, which are the only part of the papers available in English, zinc peroxide and strontium peroxide are applied as pigments, and carboxylated acrylic copolymers are used as binder material.

It is seen that strontium peroxide in its pure form is the most peroxide-liberating of the pigments.
Whereas magnesium, calcium, and strontium peroxide ultimately give alkaline by-products (group II metals), zinc peroxide is the only pigment investigated in this paper that gives amphoteric by-products when reacting with water.
In fact, bubbles were identified on coatings containing calcium and strontium peroxide in laboratory experiments.
Precipitates were identified on all coatings containing magnesium, calcium, and strontium peroxides. These precipitates were identified as carbonates by use of Fourier transform infrared spectroscopy.
