Polysulfide Adhesives, Sealants and Coatings

Polysulfide Adhesives, Sealants and CoatingsMaster Bond polysulfide formulations offer corrosion protection, superior electrical insulation and good flowability. These elastomeric compounds are 100% reactive and are designed to cure at ambient temperatures or at slightly elevated temperatures.

Properties of Polysulfide Adhesive Systems

  • Underwater curing capability
  • Exceptional chemical resistance
  • High dielectric strength
  • High physical strength
  • High and low cryogenic temperature serviceability
  • Resistance to vibration, impact, shock and thermal cycling
  • Metal free
  • Long-term resistance to gasoline, natural gas, gaseous fuels, kerosene, alcohol, crude oils and its derivatives
  • Easy application with no drip feature
  • Excellent adhesion to similar and dissimilar substrates
