Features Of Evonik Dynasylan LM 400 MEKO-free oximino crosslinker

  1. MEKO-free formulation ensures compliance with increasingly stringent VOC and regulatory requirements for construction and industrial sealants.

  2. Offers excellent storage stability in one-component moisture-curing systems without premature gelation or viscosity increase.

  3. Delivers fast surface cure at ambient humidity and temperature, enabling efficient production line throughput.

  4. Provides high crosslink density for superior mechanical strength, elasticity, and long-term durability of cured elastomers.

  5. Compatible with a broad range of silane-terminated polymers (STPs), polyethers, and hybrid resins.

Typical Applications Of Evonik Dynasylan LM 400 MEKO-free oximino crosslinker

  1. High-performance silicone-modified and hybrid construction sealants for façade, glazing, and expansion joints.

  2. Automotive under-hood and interior adhesives/sealants requiring low-odor, non-MEKO chemistry.

  3. Industrial assembly adhesives for bonding metals, plastics, and composites in electronics and appliance manufacturing.

  4. Renewable-energy applications including PV module encapsulants and wind turbine blade bonding systems.
