    Application:

    1)KH-621 is phenyl-contained Silane, which is used as cross-linking agent for silicone resin; it also used as starting material for phenyl silicone oils or phenyl-modified silicone polymers. ( leads to silanol groups that in a subsequent condensation reaction, can form stable siloxane (-Si-O-Si-) bonds.)

     2)This product also exhibits excellent thermal stability and brings flexibility to sol-gel coating systems because of its phenyl group.

     

    Usable life and storage:

    when stored at or below 25℃ in the original sealed containers, this product has a usable life of 12 months from the date of production.

    Sealed in container,keep the warehouse cool,dry and draughty.avoid dampness and water,away form fire and heat source.
