ADLER Bleichaktivator 82490 is used together with hydrogen peroxide instead of ammonia for activating the bleaching reaction (the release of oxygen from the peroxide). This product is odorless and it ensures that the hydrogen peroxide is completely decomposed (and does not lead to any later damage such as cracking in the varnish coat).


The boiling phenomena which are well known when using ammonia do not occur in the mixing of hydrogen peroxide / bleach activator. This bleach solution is active to its full effective extent for about 1 hour.

abbondant (approx. 60 - 70 g/m²) on the sanded (gran. 150 - 180)
