Industrial Applications You Can Rely On
Leather Manufacturing & Processing
In the leather industry, our product serves as a critical retanning agent. It helps fill the fiber structure of chrome-tanned leather, ensuring uniform thickness and dimensional stability. You'll notice improved handle characteristics and enhanced light-fastness in your finished leather goods.
Beverage Industry Solutions
For beverage stabilisation, wine and beer manufacturers rely on our food-grade varieties. By precipitating unstable proteins and functioning as an antioxidant to preserve colour and flavour, the natural astringent qualities aid in the clarification of liquids.
Animal Nutrition Enhancement
Our product promotes intestinal health in animals as an alternative to antibiotic growth enhancers. It enhances ruminant animals' use of protein, modifies intestinal flora, and lessens diarrhoea via natural astringency.
Additional Industrial Uses
- Water treatment (coagulation and flocculation)
- Wood adhesive formulation
- Mineral flotation processes
- Metal chelation applications
- Natural preservative systems
