NEUTRIN MT
Neutralizer/Inorganic Buffering Salts
Main features
NEUTRIN M/T is a universal neutraliser for wet bleu skin with a slow and incisive action in section, without excessive danger of overdose. Used alone, especially for footwear, it gives stabilizable sections at pH 5.1/5.4 that can be easily corrected with slight additions of traditional neutralizing agents such as sodium bicarbonate. The quantity to be used depends on the item to be produced and the thickness of the wet bleu. Prolonged rinsing is recommended after use.
Application example:
150% water 30/35° C1.5% sodium formate 20′
1.5-2% NEUTRIN M/T 40′ pH= 5.2/5.4
0.3/0.5% sodium bicarbonate 30′ pH= 5.5/5.7
NEUTRIN NT
Neutralizer/Inorganic Buffering Salts
Main features
Neutrin NT is a buffered neutralizer that acts on the skin leaving a decidedly pasty and full touch. In practice, the product acts on unfixed chromium salts, transforming them into complexes that remain on the skin. Leather neutralized with Neutrin NT has no wrinkles and/or overtanning effects as well as good dyeability.
