Features Of Evonik Dynasylan LM 200 MEKO-free oximino crosslinker

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

  2. High hydrolytic stability enables extended shelf life and reliable performance in moisture-sensitive systems.

  3. Excellent compatibility with silanol-functional polymers, including silicone hybrids and silane-modified polymers (SMPs).

  4. Fast room-temperature curing kinetics without requiring external catalysts or elevated temperatures.

  5. Low odor and improved workplace safety compared to traditional alkoxy- or acetoxysilane crosslinkers.

Typical Applications Of Evonik Dynasylan LM 200 MEKO-free oximino crosslinker

  1. One-component (1K) moisture-curing sealants for construction and façade applications.

  2. High-performance adhesives in automotive assembly and bonding of elastomeric substrates.

  3. Weather-resistant coatings and protective finishes for metal, concrete, and glass substrates.

  4. Hybrid polymer-based grouts and repair mortars requiring low-shrinkage, durable crosslinking.
