Polyether Modified Polysiloxane LA-0190
LA-0190 is a siloxane/propylene oxide copolymer. It is a 100% active polyether silicone oil with strong moisture permeability. The copolymer is water-soluble and can be dipped or sprayed to make the leather substrate water-absorbent and breathable.
Introduction
Application
It can be used for water and solvent-based leather coating, provides good flow-out, wear & scratch resistance, and silky feel.
When used in water and solvent-based paints, inks, and coatings, it has the properties of being smooth, scratch-resistant, and anti-adhesive.

Storage and Expiration Date
When stored in an unopened container at or below 25°C (77°F), the LA-0190 polyester modified polysiloxane has a usable life of 24 months from the production date.
When stored at 16°C (61°F) or below, it will atomize and solidify into wax that can be heated back into a liquid state.
Long-term storage will cause yellowing, but it will not affect the use.
