Bating Agent

Whatsapp Order

Bating Agent is a biochemical preparation used primarily in the leather processing industry during the bating stage, which follows liming and deliming. It consists mainly of proteolytic enzymes (such as pancreatin, trypsin, or subtilisin) that break down non-collagenous proteins, hair residues, and unwanted tissue from hides and skins. This enzymatic treatment softens the leather, improves its texture and pliability, and prepares it for tanning. The bating process enhances the quality, uniformity, and appearance of the final leather product.

Description

Primary Uses

Leather Processing

Used in the bating stage to enzymatically remove non-collagenous proteins and hair remnants from hides and skins.
Softens and improves the texture and pliability of leather, making it more supple.
Facilitates uniform tanning by preparing the hide structure.
Helps reduce the risk of defects like grain loosening or uneven tanning.

Waste Treatment

Applied in some effluent treatment plants to degrade proteinaceous waste from leather industry effluents.

Secondary Uses

Used experimentally in some biotechnological processes requiring proteolytic enzymes.
May be used in research for enzyme activity studies or in industrial enzyme formulations.
