Anhui IOTA Silicone Oil Co., Ltd.'s IOTA 2520 carboxy-terminated polydimethylsiloxane is transforming traditional leather processing with its unique reactivity and lasting waterproofing properties. By forming chemical bonds with leather collagen proteins, this product provides durable waterproof protection for chrome-tanned leather while imparting excellent silicone characteristics.

Technical Breakthrough Highlights

• Chemical Bonding Waterproofing: Carboxyl groups form strong covalent bonds with leather fibers, maintaining >85% waterproofing after 50 washes

• Multi-Functional Enhancement: Simultaneously improves leather softness, wear resistance, and anti-stick properties

• Eco-Friendly Process: Replaces fluorinated waterproofing agents, certified by ZDHC MRSL

• Acid-Alkali Resistance: Stable in pH 3-11 range, adaptable to various tanning processes

Leather Industry Application Effects

✓ Premium Shoe Leather: Waterproof performance unchanged after 100,000 dynamic flexes
✓ Automotive Interiors: Rub fastness improved by 1.5 grades
✓ Outdoor Equipment: Enhanced weather resistance, stable from -20°C to 80°C
✓ Light-Colored Leather: Zero yellowing, 100% whiteness retention

"Traditional waterproofing agents only provide temporary protection, while IOTA 2520 achieves permanent waterproofing through chemical bonding," stated IOTA's Technical Director. "This is particularly outstanding in high-end outdoor leather products."
