Description
Silway 9201 is a linear polydimethylsiloxane with an alcoholic hydroxyl on both
ends (ABA glycol siloxane). Unlike other ABA glycol siloxanes, Silway 9201 does not
contain excess unreacted monofunctional organic glycol which can impair the isocyanate
reactivity of a polyurethane, resulting in a polyurethane with inferior crosslinking.
Because of its high purity, Silway 9201 reacts to form a high quality polyurethane. It
is therefore most suitable as a urethane modifier for synthetic or artificial leather where a
high degree of softness is required.
Typical Applications
As urethane modifier to improve softness, flexibility, lubricity, breathability, compatibility, abrasion resistance and water repellency of synthetic leather.
Key Feature
--React with isocyanate group to
--silicone/PU polymer
--Improved centrifugation type
--Good lubrication
--Provide abrasive-resistance and scratch- resistance
--Provide hydropgobic ability
--Improve softness and folding-resistance
--Superior moisture penetrability
