Chemical Family: Isocyanates, SilanesIsocyanatesSilanes
Molecular Weight: 205.0 - 205.0 g/mol

Silquest™ A-Link 25 silane and Silquest™ A-Link 35 silane are 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.
