Evonik Dynasylan MKS Hydrolyzed Polyethyl Silicate Silicate Coupling Agent

Evonik Dynasylan MKS is a hydrolytic polyethyl silicate coupling agent, optimized for single-component zinc-rich coatings. Its amino-curing system enables moisture-triggered crosslinking, forming durable anti-corrosion layers on steel. With excellent anti-settling properties and solubility in aliphatic/aromatic solvents, it ensures long-term storage stability. Ideal for heavy-duty industrial protection, compliant with REACH standards.

Features Of Evonik Dynasylan MKS Hydrolyzed Polyethyl Silicate Silicate Coupling Agent

  1. Moisture-Curing - Amino groups facilitate ambient humidity curing, eliminating oven drying needs

  2. Anti-Settling - Maintains zinc particle dispersion for >12 months without hard sedimentation

  3. Corrosion Resistance - Forms SiO₂-rich networks, achieving >1,000 hours salt spray resistance.

  4. Process Flexibility - Compatible with spray/brush application and solvent blends (e.g., xylene/butanol)

Typical Applications Of Evonik Dynasylan MKS Hydrolyzed Polyethyl Silicate Silicate Coupling Agent

  1. Marine Coatings - Zinc-rich primers for ship hulls/offshore platforms.

  2. Industrial Maintenance - Steel structure protection in chemical plants

  3. Automotive Undercoats - Anti-rust treatments for chassis/components
