Application of Hydrophilic Smooth Silicone Oil 6638

Time:   Click: 174


Physical and Chemical Indicators

  • Model: Hydrophilic stiff smooth silicone oil 6638

  • Main component: Polymer complex

  • Appearance: Milky white liquid

  • Ionicity: Weak cationic

  • pH value: 5.0~6.0

Working Mechanism

Efficient surface filming property

The efficient surface filming property ensures the stiffness and smoothness of the fabric surface.

Superb penetrability into the fabric

Under the action of superb penetrability, the silicone oil enters the fabric, greatly enhancing the fabric's drape effect.

Excellent binding force for a more relaxed, thick, and elastic fabric

After fabric shaping, the soft segments reduce the friction coefficient between the fibers, resulting in excellent elasticity of the fabric.
