3-Isocyanatopropyltrimethoxysilane(CAS:15396-00-6) is a silane with isocyanate functional groups, which is used as a crosslinking agent and adhesion promoter in adhesives and sealants. It can adhere to various substrates, common and uncommon; outstanding wet adhesion performance on glass, metal and other inorganic substrates; also can adhere to difficult-to-adhere substrates, such as nylon and other plastics products. It can be hydrolyzed quickly in the presence of atmospheric humidity and has very good thermal stability, chemical stability and UV stability. Suitable polymers: acrylics, silicone resins (Si), PU-prepolymers, etc.

Silane OSi HIOSil SL35 is unique Isocyanate functional silane. The Isocyanate functionality exhibits the typical reactivity of an alkyl Isocyanate and will react with the most active hydrogen-containing compounds. The silane portion of the product can then crosslink with each other or be used to adhere to a variety of substrates.
● 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
1. NCO-free polyurethane systems.
2. Moisture curing at room temperature.
3. Can be used as one-component or two-component.
4. It has a wide range of synthesis and formulation design.
5. Improved adhesion to different substrates.
6. Improved UV stability.
7. good storage stability.
8. Excellent chemical resistance.
9. Can be used as a low, medium and high modulus sealant.
Their unique functionality makes them excellent candidates for use as:
● Crosslinkers for one-part moisture-curable urethane adhesives, sealants, and coatings when used to end cap diol or polyol polymers.
● Adhesion promoters for one-part moisture curable and two-part reactive urethane systems.
● Adhesion promoters for silicone sealants or coatings seeking enhanced adhesion to organic substrates on which active hydrogen species are present, such as nylon or other plastics.
