Frequently Asked Questions
Find answers to common questions about our products and services
Syntans are synthetic tanning agents used in leather processing to improve fullness, softness, and dye receptivity. They enhance leather quality, provide better grain characteristics, and improve the overall properties of finished leather products.
Liquid syntans are ready-to-use solutions that offer convenience and easy application. Powder syntans require dissolution but offer longer shelf life and can be customized for specific applications. Both provide excellent tanning and filling properties.
Syntans improve leather fullness, softness, grain tightness, dye receptivity, and overall quality. They help produce high-quality leather goods with consistent properties and enhanced performance characteristics.
Leather processing involves various chemicals including beam house chemicals (for soaking, liming, and bating), syntans (for tanning and filling), fatliquors (for softening and conditioning), dye fixers (for color stability), and finishing chemicals (for final treatment and protection). Our comprehensive range covers all stages of leather processing from raw hide to finished leather.
Fatliquors are essential chemicals used to impart softness, flexibility, and durability to leather. They lubricate the leather fibers, prevent brittleness, and ensure the leather remains supple and comfortable. Our fatliquors are formulated to provide optimal softness while maintaining leather strength and quality.
Dye fixers are chemicals that improve the stability and fastness of dyes on leather surfaces. They help prevent color bleeding, improve color uniformity, and enhance the resistance of dyed leather to water, light, and rubbing. This ensures vibrant, long-lasting colors in finished leather products.
Beam house chemicals are used in the initial stages of leather processing, including soaking (to rehydrate hides), liming (to remove hair and flesh), and bating (to remove lime and prepare for tanning). Our beam house chemicals effectively remove impurities, condition the material, and prepare hides for the tanning process.
Yes, we are committed to environmental sustainability and offer leather chemicals that comply with international standards. Our products are developed with a focus on reducing environmental impact while maintaining high performance. We provide solutions that help tanneries meet regulatory requirements and sustainability goals.
