Product Description
Nut mordant 100% water soluble powder super sodium humate


Nut mordant is a sodium salt of humic acids, produced from lignite. It is natural, dark brown mordant, soluble in alkalis and water (up to 98%). Insoluble particles are mainly compounds of different clays and have no negative effect on reactivity. The basic coloring components are humic acids.
It is produced in the form of fine metal bright flakes of dark brown color.
The pH of the 10% water solution is about 10.


Nut mordant is used for coloring of paper, especially cardboard and wrapping.


Mordant is usually added into the broke beater soluted in water in concentration from 1: 4 to 1: 10 or directly in the form of solid flakes.
The content of nut mordant is, according to desired shade of colour, 2-8% of the dry paper matter (dried in the open air). The matter is mixed properly and then is added solution of aluminium sulphate Al2(SO4)3. This solution regulates the fine precipitation of dyestuff. Should be achieved The acid medium (pH value about 5) is optimal for proper precipitation. Then, after pressing the paper stuff, the outflowing water should be clear.


Surface dying is usually done on the size press, where 10% solution of the Nut mordant is distributed on the upper layer and at the same time is on the bottom layer distributed colored or uncolorod starch. Into the defibred paper is usually added solution of aluminium sulphate Al2(SO4)3 before spraying on the rolls. Nut mordant consumption is according to the desired shade about 0, 25% of mass, related to the weight of the upper layer, dried in the open air.
When necessary to obtain specific shade of color, Nut mordant is very good mixable with other commonly used colors.


Coloured paper has very good fastness to light.
Reactivity of humic acids improves density, surface strength, puncture and bending resistance, initial tearing strength and sizing of the final product.
Total yield grows up because the mordant has gone, under optimal conditions, entirely into the paper.
Chemical structure of nut mordant helps to regulate moisture in the final product.
High chemical reactivity helps to form bonds with heavy metals during the production process, which prevents uncontrolled coagulation and improve purity of waste water.


Nut mordant acts as a complex agent, which apart from its coloring effects, helps to improve physical characteristics of final product. Connection with the favourable price creates good conditions for its application in production.


Nut mordant has been successfully used already for decades, not only in Czech Republic, but also in Slovakia, Germany, France, Italy and other countries.
