- Application
- Andisil® 35 Silane is a colorless, low viscosity liquid. It has unique isocyanate functionality that 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.
- Application and Performance
- Provides good adhesion to difficult substrates when used as an adhesion promoter
- Provides superior wet adhesion to glass, metal and other inorganic substrates resulting in a bond that offers excellent thermal, chemical and UV stability
- Used as crosslinker for Polyurethane polymers (SPUR)

Technical Details & Test Data
- Reactivity
- Andisil® 35 Silane can react with -OH, -NH2, and -SH functional polyols and providing a moisture-cure silane crosslink mechanism. For primary OH-functional materials with two- or more –OH functions per molecule such as polyether, polyacrylate, and polycarbonate, the isocyanate group will rapidly react at relatively low temperatures (40 - 80C). This allows the conversion of a thermoplastic material to a thermoset material once reacted with moisture. Generally, a 3-10% excess of isocyanate is needed to assure a thorough reaction of all –OH.
