CHEMTAN N-34R Magnesium oxide

Basic physical properties:
Ingredients: Magnesium oxide 98%
Nature: CHEMTAN N-34R is a high purity magnesium oxide, with alkaline powder. It is insoluble in water and dissolves in the slightly acidic solution, so it can be added to the chrome tanning solution to slowly increase the pH to the proper salt base.

Instructions for use:
CHEMTAN N-34R is very suitable for chrome tanning, as the automatic adjustment of salt base, it can replace some of the base, to improve the degree of salt without excessive, and then produce chromium powder precipitation on the surface. 0.3% ~ 0.5% CHEMTAN N-34R can be added with chrome powder or chrome tanning after use; the initial use should be checked to adjust the degree of salt of the PH, if the amount can be applied to achieve the required salinity; the use of CHEMTAN N -34R can be chrome tanned overnight.

The main advantages of CHEMTAN N-34R:
A) CHEMTAN N-34R is a gradual increase in the gradual increase in PH, and no general salt to adjust the shortcomings of additives; it can promote uniform penetration of chromium powder.
2) CHEMTAN N-34R will not make chrome tanned leather face friction.
3) CHEMTAN N-34R can promote the leather grain surface smooth, chrome tanning even uniform and even dyeing.
