A viable alternative to solvent-based bonding agents for rubber-to-metal anti-vibration applications is now available from Dow. The new generation of MEGUM™ water-based primer and cover coat systems provides outstanding performance – equal to solvent-based formulations – with significantly reduced VOCs – all at a competitive cost.

“Making products with a lower environmental impact without sacrificing performance is a proud achievement,” said Dr. Stefan Dehnicke, global technology manager – Specialty Adhesives at Dow Automotive. “A 75 percent water-based formulation allows the possibility for new optimized manufacturing footprints with no atmospheric pollution. This accomplishment sets a new standard in rubber-to-metal bonding, including dynamically challenging applications.”

MEGUM™ water-based bonding agents are available as both primer and cover products that can be used together or separately. Product advantages include:

  • Bond strength fully compatible to solvent-based systems on natural rubber, NBR, HNBR and EPDM.
  • Excellent performance in dynamic real parts testing with EPDM – at the same levels as used for solvent-based standards
  • High salt-spray and corrosion resistance
  • Non-flammable
  • High solids, low viscosity with the opportunity to spare dilution
  • Advantaged economics versus solvent-based agents
  • High flexibility, water-based primer MEGUM W 9300
