Silway 9201
 
 
Silway 9201 is a linear polydimethylsiloxane with hydroxypropyl  terminated on double ends . Various properties of Silway 9201, such as wear resistance, softness, etc., are better than the general polyether modified silicone oil with primary hydroxyl groups.    Unlike other polyether modified silicone oil, Silway 9201 does not contain excess unreacted monofunctional hydroxyl group which can impair the isocyanate reactivity of a polyurethane, resulting in a polyurethanewith inferior crosslinking.
 
Silway 9201 polyurethane modifier (PU modifier) is a modifier used in polyurethane production. Moreover, Carbinol Silicone Oil (CAS No.222416-17-3) is often used for the modification of polyurethane resins.
 
Typical Applications
  • PU dry resin  
  • PU waterborne resin  
  • PU surface treatment agent
Key Features
  • Reactive with isocyanate to give silicone/PU copolymer
  •  Increase release properties
  • Good lubricity
  • Provide abrasion and scratch resistance
  • Provide water repellency
  • Softening and flexibility
  • Good water vapor permeability
Usage
The general effective concentration of Silway 9201 is 1.0~5.0% of the formula weight. The specific amount depends on the type of formulations, solvents and resin systems. It is recommended to add Silway 9201 to PU prepolymer formula in the front section.
