Wet-end leather dyeing auxiliaries that improve dyestuff performance
From automotive leather to upholstery, and from waterproof to metal-free tanning, Muno’s wet-end leather dyeing auxiliaries improve dyestuff performance for leather used in all kinds of applications. Besides being ZDHC MRSL compliant – they are included in our Neo® Portfolio - our wet-end leather dyeing auxiliaries enable tanners to achieve the desired shades of color and so meet customer demands.
Product | Type | Application | Main features |
|---|---|---|---|
Dermagen® GP liq Dermagen® GPA liq | Ethoxylated Alkylamine derivate, anphoteric character | Levelling and Penetrating agent | Dyestuff-substantive agent. It forms a loose complex with anionic dyes that enhances the dye mixture combinability, improving its penetration without reducing de depth of the final shade. |
Corilene® LVI liq Corilene® LVG liq | Ethoxylated Oleilamine | Levelling and Penetration agent | Dyestuff- substantive agent that balance the affinity between different dyestuffs, Dyeings obtained show an outstanding levelness and penetration, without reducing the intensity. |
Egalux® LN liq | Cationic Ethoxylated amine derivate | Levelling agent for wool and hair dyeing | Levelling agent which minimizes the different affinity of dyes for the wool or hair, contributing to achieve a more uniform shade along the wool / hair fiber, as well as between different wool nature skins. |
Penetrator® PTR liq | Polyethoxylated glycol compound, non ionic character | Penetration agent | Penetration auxiliary which helps to the diffusion of the anionic dyes or chemicals into the leather cross-section. When is mixed with the dye solution product increases the dye penetration level without altering the final color or intensity. |
Dermafix® P liq | Aliphatic polyamine derivate, strong cationic character | Fixing agent | Formaldehyde free auxiliary, suitable to increase wet fastness mainly perspiration when is applied in fresh bath alone at the end of process. It can be used also as build- up agent, but due to its strong cationic character, fatliquors and unfixed dyestuff can precipitate on leather surface if intermediate washing is not made properly. |
Dermafix® PF liq | Polymer strongly cationic | Fixing agent | Formaldehyde free auxiliary suitable to increase wet fastness, mainly perspiration, when is applied in fresh bath alone at the end of process. High heat resistance. Due to its strong cationic character it can´t be applied in same bath than anionic tanning agents or fatliquors. |
Dermagen® DMA liq | Quaternary ammonium compound, weakly cationic | Build-up agent | Dying assistant used to increase the depth of the color on low affinity leathers, when is applied as top-dyeing it improves the dyestuff build-up. Resulting dyeings maintain an optimal levelness, also between the grain and flesh side. |
Dermafix® OK liq | Ethoxylated fatty amine derivate, cationic character | Build- up agent | Auxiliary used in top-dyeing to increase the dyeing depth in low affinity leathers, achieving brilliant and deep shades. It is also recommended for wetting back chrome-tanned crust. |
Dermafix® S-IN liq | Polyamine based with strong cationic character | Build- up agent | Used to improve the shade depth on top dyeing in leathers heavily retanned with vegetables and synthetic chemicals. A few amount is needed to produce deep black or brown shades. When it is applied at the end of the process improves fixation and bath exhaustion. |
Eusapon® LPK-E | Fatty alkyl and ether sulphate compound | Washing agent | Auxiliary used in the production of all types of Fur and Wool skins, from raw skins to dressed or dyed. Excellent washing, wetting and dispersing action. |
Dermaflux® DO liq | Ethoxylated fatty acid | Deodorizing agent | Agent specially designed to neutralize unpleasant odors in the leather. Long lasting fragance retention, with excellent penetration into the leather without altering its properties. |
Coralon® NL liq | Salts of organic acids and anionic polyols | Neutralizing agent | Thanks to its special chemistry and buffering ability, when used as auxiliary in dyeing, the levelling, dye distribution and penetration is improved, obtaining brilliant shades. |
Coralon® OT-IN | Naphtalene Sulphonic acid compound | Dispersing agent | Anionic dispersing agent to speed up the penetration and uniform distribution of retanning agents, vegetal extracts and dyestuffs. Low formaldehyde content. Moderate heat resistance , lightfastness and beaching effect. |
Coralon® M | Naphtalene sulphonic acid compound | Dispersing agent | Anionic dispersing agent to speed up the penetration and distribution of retanning agents, vegetal extracts and dyestuffs. Low formaldehyde content. Moderate heat resistance, lightfastness and beaching effect. |
Densotan® A | Anionic polymeric compound | Dispersing agent | Special dispersing auxiliary that increases the retanning agents and dyes distribution, increasing levelness and defect coverage. Formaldehyde free and free of emulsifiers, suitable to produce waterproof articles. |
Coralon® NNOL | Aromatic sulphonic acid condensation compound | Dispersing agent | Anionic dispersing agent to speed up the penetration and distribution of retanning agents and dyestuffs. Low formaldehyde content. Excellent heat resistance and lightfastness, showing strong beaching effect suitable to produce pastel shades. |
Auxiliaries that enhance the performance of wet-end dyestuffs
Our wet-end dyestuffs portfolio include a variety of specialities that optimize their performance. Our auxiliaries do this by, among other things, increasing and accelerating the dyestuff penetration, improving the dyeing levelness, increasing the shade depth, the fastness levels or contributing to the retanning agents distribution.
