CHT offers formulation assistance with water-resistant silicones for wet-end and leather finishing.
Formulators need an appropriate carboxy-functional polydimethylsiloxane to impart water repellence for wet-end processing. This process exploits the carboxy functionalities to bind the silicone to the leather fibre. Leaving the silicone to exploit its natural hydrophobicity to protect the leather. See our flyer that shows how CHT product transform formulations to significantly enhance the penetration within the fibres and improves the final performance.
Special reactive emulsions can be used alone or in combination with standard anionic waterborne binders in leather finishing. These can replace fluorocarbon resins which are known to cause environmental issues, especially in wastewater. For this reason, CHT offers sustainable solutions for replacing fluorocarbons in leather formulations.
