A-Link 25 and A-Link 35
Technical Data Sheet
Silquest* A-Link* 25 and Silquest A-Link 35
Description
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.
Key Features and Typical Benefits
Features and Typical Benefits of Silylated Urethanes: Isocyanate Functionality
Trimethoxysilyl (Silquest A-Link 35 silane)
Reactive with -OH, -NH2, and -SH functional polyols and polymers, providing a moisture-cure silane crosslink mechanism
Provides good adhesion to difficult substrates when employed as an adhesion promoter
Offers fast hydrolysis in the presence of atmospheric moisture
Provides superior wet adhesion to glass, metal and other inorganic substrates
Resulting bond offers excellent thermal, chemical and UV stability
Triethoxysilyl (Silquest A-Link 25 silane)
Provides slower hydrolysis for applications requiring greater open time or enhanced shelf stability
Provides superior wet adhesion to glass, metal and other inorganic substrates
Resulting bond offers excellent thermal, chemical and UV stable performance
