CryoFlex-C2R: Development of Cold Crack Resistant Fatliquor for Extreme Low­Temperature Leather Applications 

CryoFlex-C2R is a specialty cold crack resistant fatliquor technology developed by CSIR-CLRI for leather applications requiring performance under extreme low-temperature conditions. The technology enables leather to retain flexibility, softness, and mechanical integrity at temperatures as low as -40 °C. It is an indigenously developed formulation designed to address the lack of specialty fatliquors suitable for extremely cold regions and automotive leather applications. 

• Automotive leather (car seats, steering wheels, interiors)
• Garments and upholstery leather
• Footwear upper leather
• Defense and high-altitude leather applications (Siachen, Kargil, mountainous regions.

• Maintains leather flexibility and softness up to -40 •c
• Prevents cold crack formation and surface stiffness
• Withstands continuous bending and flexing without surface damage
• Ensures deep fiber lubrication and enhanced durability
• Compatible with all common fatliquors
• Eco-friendly, non-toxic, and cost-effective formulation
• Fully indigenous technology supportingAtmaNirbhar Bharat
