Features Of Evonik Dynasylan LM 100 MEKO-free oximino crosslinker

  1. MEKO-free formulation ensures compliance with increasingly stringent VOC and occupational health regulations.

  2. Highly reactive oximino functionality enables rapid, ambient-cure crosslinking with silanol-terminated polymers.

  3. Excellent hydrolytic stability supports extended shelf life and consistent performance in moisture-sensitive formulations.

  4. Low volatility and favorable odor profile enhance workplace safety and operator acceptance.

  5. Enables high-performance, non-yellowing elastomeric networks ideal for demanding architectural and industrial sealants.

Typical Applications Of Evonik Dynasylan LM 100 MEKO-free oximino crosslinker

  1. One-component (1K) neutral-cure silicone and silane-terminated polymer (STP) sealants.

  2. High-end construction joint sealants requiring low modulus, high movement capability, and UV resistance.

  3. Automotive under-hood adhesives and anti-vibration gaskets where thermal stability and low emissions are critical.

  4. Industrial bonding agents for glass, metal, and coated substrates in façade and curtain wall systems.

  5. Specialty encapsulants and potting compounds for electronics protection in humid environments.
