RESEL® ~ Polyurethane Resins BLOCKING
 

PRODUCT INFORMATION

These resins have been used for more than 15 years in the areas of Telecom and E/E.

Can be used to replace unsaturated Polyester, Epoxy resins, and silicone rubber

Advantages over other Polyurethane systems:

  • Low tension up to high hardness
  • Better resistance to water permeation (including water vapor)
  • Better hydrolytic stability
  • Better absorption to sound and impact
  • Improved handling properties (low sensibility to moisture, therefore less gassing)
  • Low viscosity, excellent adhesion, chemical resistance
  • Excellent electrical properties

Advantages over other systems:

  • Cost advantage over epoxy cured systems
