RESITEL® É Polyurethane Resins BLOCKING
 

PRODUCT INFORMATION

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
  • Easy to mix, cured at room temp
  • Excellent tensile strength properties
  • Low heat emissions during cure, low shrinkage (therefore does not affect equipment sensitive to pressure and temperature)

These resins do not corrode in contact with copper and are compatible with all materials that are mostly used in electric equipment.

RESITEL resins have been widely accepted in Telecom and E/E industry.

Most frequent applications are: pressure blockage and telephone cables splicing, voltage regulators, transformers, capped cables, circuit covers, transistorized ignition systems and impact absorbers

Dielectric Constant @ 25°C (ASTM D - 150) 10 Hz
Dissipation Factor (ASTM D - 150) 10 Hz
Insulation Resistance (ASTM D-257) 10 ohms
 
RESITEL® 003 ARD
Pressurization Blocking ..(low viscosity)
Low viscosity resin used to block out moisture and pressure. It is applied using gravity method. Mostly used in cabinet cubicles, cabeçotes and CBTP kit's with pressure outlets.
