The CROMOXYL® series of colourings is made up of a selection of type 1:2 sulphonated premetallized colourings, especially suited for dyeing wood.
Their features are :

- Easy to use
- High lightfastness
- Good surface penetration
- Good compatibility with normally employed additives

THE CROMOXYL® colourings have good stability with peroxide-based varnishes. Since this property is strongly affected by the type of varnish and the operating conditions, it is advisable to carry out tests in order to ascertain the suitability of the product.
If dying wood that has been bleached with hydrogen peroxide, sodium hydrosulphite, sodium hypochlorite, etc. , it is advisable to wash the item carefully before applying the dye.
The usage pH can go from 5 to 9. The presence of ammonia can slightly change the colour hue, which in any case will remain stable over time.

Available forms :

- Concentrated aqueous solution coding /L
- Concentrated solution in a solvent mixture coding /LD or /LND
- Powder/granules with a low content of Inorganic Salts (< 1%) coding /C

The CROMOXYL® colourings are used in wood dyeing with water-based, glycol ether-based and ketone-based solutions and various blends of these solutions.
The presence of organic solvents, besides speeding up the drying process, increases the brightness of the colour.
