Product Description

Carboxy-terminated Silicone Oil IOTA 2520

Description:
IOTA 2520 is a carboxy-terminated polydimethylsiloxane, designed to impart long-lasting waterproof properties to chrome-tanned leather, while also endowing it with certain silicone characteristics.

Applications:
• Long-lasting waterproofing of chrome-tanned leather 
• Hydrophobicity on polar surfaces
• Enhancing compatibility with organic polymers during pigment or filler treatment
• Chain extender for polymers (e.g., introducing in polycondensation reactions of polyesters, polyamides) to impart silicone properties
• Hydrophilic soft finishing of fabrics

Advantages:
• Excellent long-lasting waterproofing
• Good compatibility with pigments or fillers
• Imparts silicone properties to polyesters, polyamides: anti-blocking, anti-stick, abrasion resistance, scratch resistance, etc.
• Provides a smooth feel to fabrics while enhancing their hydrophilicity
• Non-yellowing, suitable for use on white or light-colored leather or fabrics
• Stable micro-emulsion, resistant to acids, alkalis, and shearing
