Molecular Formula: C10H21NO4Si

Chemical structure: 

Equivalent Brand: A-Link25 (Momentive); KBE-9007 (ShinEtsu)

Silane RJ-887 is colorless clear liquid. It is unique isocyanate functional silanes. The isocyanate functionality exhibits the typical reactivity of an alkyl isocyanate and will react with most active hydrogen containing compounds. The silane portion of these products can then crosslink with each other or be used to adhere to a variety of substrates.
