Hydrogen peroxide 35%

After maceration, the cleanly rinsed bones are placed in the bleaching solution without intermediate drying. Thanks to the addition of SUPRALAN UF, not only is there excellent penetration of the bones, but also further degreasing of the material.

Once the bones have reached the desired level of bleaching, they are removed from the bath, rinsed well and dried slowly. It is important to note that the bones appear lighter after drying (due to the change in the refractive index after drying).

The amount of SUPRALAN UF added to the liquor depends on the fat content of the bones to be bleached. Increasing the amount of hydrogen peroxide added does not lead to better bleaching, but only to a higher consumption of the substance. Heavily discolored bones must be treated over a longer period of time and the bleaching liquor may need to be changed several times.

HYDROGEN PEROXIDE 35%

for industrial and technical applications

Hydrogen peroxide is a colorless, largely stable liquid compound of hydrogen and oxygen. It is slightly more viscous than water, a weak acid and a very strong oxidizing agent for most substances, which as such reacts violently with substances such as copper, brass and potassium iodide and thus acts as a powerful bleaching and disinfectant.
Hydrogen peroxide is a bleaching agent. The most common use worldwide is for bleaching pulp. In the trade, wood is bleached with hydrogen peroxide during restoration or renovation, thereby making it lighter.
During interior renovation, mold infestation can be combated with hydrogen peroxide; the oxidizing and bleaching effect removes the mold residues from porous surfaces and makes them invisible.
In microelectronics, the mixture of sulfuric acid and hydrogen peroxide is used to clean the surface and remove photoresists from wafers.
In the production of printed circuit boards (PCBs), concentrated hydrogen peroxide-containing copper chloride etching baths are used to remove the copper.
