The material
How this grade works and where it fits — exact parameters are defined in the TDS.
Hexamethylcyclotrisilazane is a six-membered ring of alternating silicon and nitrogen atoms. The material hydrolyses readily: contact with moisture forms silanol and releases ammonia. Close the container immediately after use and work in a well-ventilated area. Opening the ring is the route to high-molecular-weight polysilazanes, which is what makes this grade a starting material rather than a finished product.
Choose this grade to build your own polysilazane by ring-opening polymerisation, or as a methyl-functional crosslinker. For vinyl functionality — radical and hydrosilylation chemistry — use EK-S8002 instead.
Suitable for
Industrial applications within the TDS parameters
Metal, glass, ceramic and stone substrates — per grade
Professional application and curing processes
Not intended for
Consumer or DIY use — industrial B2B supply only
Conditions outside the parameters defined in the TDS
Food-contact or medical use unless explicitly confirmed
Applications
Recommended application areas for this grade, based on its TDS. Application fit is confirmed during technical review.
Ring-opening polymerisation to high-molecular-weight polysilazanes. Precursor for silicon carbide and silicon carbonitride ceramics. Crosslinking agent for silicone rubber. Additive for engineering plastics. Modifier for inorganic powders.

Substrates & storage
Compatibility and handling essentials — confirmed per grade in the TDS and SDS.
Suitable substrates
Steel and stainless steel
Aluminium and other metals
Glass and ceramics
Stone and mineral surfaces
Not applicable — this grade is a raw material for synthesis and formulation, not a surface treatment.
Storage, packaging & transport
Supplied in 1 L aluminium bottles. Factory standard packaging per the technical description: 25 L and 200 L drums, iron or plastic. Custom packaging on request. Stored and transported as a non-dangerous chemical. Keep containers closed, in a cool, dry, well-ventilated place away from open flame and water. Shelf life 12 months from the production date; after that the material may be used once it passes re-inspection.
