Amino Silane
Crosslinkers & Silazanes
Crosslinkers are agents that form covalent bonds between polymer chains, creating a three-dimensional network. This process enhances mechanical strength, thermal stability, and chemical resistance. Silane crosslinkers, containing functional groups like alkoxy or acetoxy, react with polymers to form durable Si-O-Si bonds, improving properties such as elongation and tear resistance.
Silazanes, compounds with Si-N bonds, serve as crosslinkers in polymer chemistry, offering unique properties for advanced material applications.

Silico Silane Crosslinkers & Silazanes for High-Performance Polymers
Silico provides high-quality silane crosslinkers, also known as silane crosslinking agents, for global customers. These crosslinkers enhance the mechanical and chemical properties of various organic polymers, including polyethers, polyesters, acrylates, and polyurethanes. They improve elongation, tear resistance, and abrasion resistance, making materials more durable and reliable.
Main Silane Crosslinkers
Silico offers a range of crosslinkers, including:
- VTAS (Vinyltriacetoxysilane, CAS No. 4130-08-9)
- MTAS (Methyltriacetoxysilane, CAS No. 4253-34-3)
- VOS (Vinyltris(methylethylketoxime)silane, CAS No. 2224-33-1)
- MOS (Methyltris(methylethylketoxime)silane, CAS No. 22984-54-9)
- TEOS (Tetraethyl orthosilicate, CAS No. 78-10-4)
VTAS and MTAS are widely used in one-component room temperature vulcanized silicone rubber (RTV), adhesion promoters for medical silicone rubber, and curing agents for silicone putty. TEOS acts as a silica source for zeolite synthesis and as a key crosslinking agent for silicone rubbers.
Silazanes & Applications
Silico also offers high-performance silazanes:
- Hexamethyldisilazane, CAS No. 999-97-3 – Used as a blocking agent, adhesion promoter for photoresists, and alternative to critical point drying in electron microscopy.
- 1,3-Divinyl-1,1,3,3-Tetramethoxydisilazane, CAS No. 7691-02-3 – Ideal for silicone resins and rubbers, especially in vinyl silicone resin production and photoresist adhesion improvement.

How to Select a Crosslinkers & Silazanes？
Selecting the right crosslinkers and silazanes depends on key factors:
- Compatibility – Ensure the crosslinker works with your polymer type (e.g., amines, carboxyls) and dissolves in your medium.
- Functionality – Choose between homobifunctional (same reactive ends) for simple reactions or heterobifunctional (different ends) for controlled processes.
- Flexibility & Stability – Spacer arm length affects material strength and flexibility.
- Reversibility – Some crosslinkers can be broken down under specific conditions if needed.
- Reaction Conditions – Consider pH, temperature, and buffer systems to ensure effective crosslinking.
Selecting the right type ensures durability, chemical resistance, and performance for your application.
