Sulfonated Fatliquor
The Sulfonated fatliquoring agent is the core basic material in the leather fatliquoring system and is also one of the most produced and widely used types of fatliquoring agents. It introduces sulfonic acid groups (-SO₃H) into the lipid molecules through chemical methods, enabling the originally hydrophobic natural or synthetic lipids to acquire excellent water emulsification ability and bonding ability with leather fibers.

Sulfited fish oil
The Sulfuric acidified fish oil is one of the most typical representative products in leather finishing agents, and is hailed as the “all-purpose finishing agent”. Through chemical modification of natural fish oil and introducing hydrophilic sulfonic acid groups, it transforms from ordinary oil to a high-performance finishing material with excellent emulsion stability and resistance to acids and electrolytes.

General Purpose Synthetic F...
1: MKL has excellent plumpness and can maintain the firmness of the leather base, suitable for various soft and hard styles, and is a relatively universal emollient agent.
2: MKL can be used together with various emollients. It can be used for firming styles or for cracking patterns styles.
3: MKL has excellent resistance to light, heat, and stability.

Phospholipid synthesis oil
The Phospholipid synthesis oil, in the field of leather chemical processing, should be more accurately referred to as synthetic phospholipid emulsifier. It is a high-end material in modern leather emulsifiers that combines natural characteristics with synthetic properties. It is produced by chemically modifying or physically blending natural phospholipids (such as soy lecithin) with synthetic components (such as synthetic phosphates, synthetic softeners). Its purpose is to give leather extreme softness, unique velvet texture, and excellent filling effect.

Replacement-type synthetic ...
The Replacement-type synthetic tanning agents are the core members of the synthetic tanning agent family and are hailed as “complements to plant tanning agents”. Unlike auxiliary-type synthetic tanning agents (which mainly function to disperse and homogenize) that only have dispersing and leveling effects, replacement-type synthetic tanning agents themselves possess significant tanning capabilities and can replace a portion or even most of the plant tanning agents (kautu) for leather tanning. At the same time, they can also give leather better light resistance, softness and filling properties.

Formaldehyde-free melamine
The most prominent feature of the formaldehyde-free melamine tanning agent is its selectivity for filling.
It can preferentially fill the soft areas such as the edges and abdomen of the leather, effectively solving the problem of loose surface, while maintaining the natural grain lines in the firm areas such as the back spine line.
-
Amino resin
The Amino resin tanning agent is the “master of shaping” in the leather re-tanning process. Through excellent selective filling, it precisely acts on the soft areas such as the edges and seams of the leather, effectively reducing part differences and solving the problem of loose surface. At the same time, it gives the leather a unique feel of fullness, firmness and elasticity. If acrylic tanning agent is responsible for “filling and softening”, synthetic tanning agent is responsible for “comprehensive adjustment”, then the specialty of amino resin tanning agent is “firm shaping and selective filling”.
-
synthetic tanning agent
The Syntan is the most widely used and diverse type of material in leather chemistry. It can be regarded as a kind of tanning agent “customized” through chemical methods. It mimics the structure of plant tanning agents, but has more flexible and controllable properties. It is the core means for regulating the feel, filling property, dyeing performance and cost reduction of leather in modern leather manufacturing.
-
Neutralisation Tannin
The Neutralizing tannin is a specific synthetic tanning agent used in the leather re-tanning process. It is mainly applied in the neutralization process of chrome-tanned leather. Its core function is not simply to neutralize the alkali, but to moderately adjust the pH value of the leather blank through its buffering and restraining properties, while loosening the fibers and firming the surface texture, thus creating the best conditions for subsequent re-tanning, dyeing, and oiling.

Acrylic retanning agent PB
The Acrylic tanning agent is one of the most crucial materials in the leather re-tanning process. It mainly addresses the unevenness of leather by selectively filling the loose areas of the leather (such as the abdominal and flank regions), thereby improving the quality of the leather in terms of fullness, softness, and light resistance. It is an indispensable material in the production of modern high-quality leather, including sofa leather, shoe upper leather, and clothing leather.
-
Soaking auxiliary agents
Soaking aid are key materials in the leather production preparation stage. They are mainly used to quickly and evenly restore raw hides (especially salted wet hides or dry hides) to the fresh hide state, while cleaning off dirt and some oils on the hides, laying a solid foundation for subsequent processing.

Tile glaze rheology modifier
HD1211 This is a white semi-transparent suspension agent composed of polymerization. It has wide applications and is suitable for paints, colorants, inks and pigments.This product helps to enhance gloss and color intensity, significantly reduces viscosity, prevents pigment agglomeration, and improves the storage stability of the system. It is applicable for the dispersion and grinding of various systems containing or not containing resins. It does not contain alkylphenol ethoxylates.
