EPIKURE™ Curing Agent 3202

 

 

Product Description

EPIKURE Curing Agent 3202 is a modified aliphatic amine. It is compatible with both reactive diluent modified epoxy resins and conventional bisphenol A epoxy resins. EPIKURE 3202 is compatible and can be used in combination with most aliphatic and cycloaliphatic amine curing agents to modify handling characteristics or cured state properties.

 

Application Areas/Suggested Uses

  • General purpose casting and encapsulation
  • Low VOC

 

Benefits

  • Low viscosity
  • High reactivity at room temperature
  • Low color
  • Good chemical resistance

General Information

EPIKURE 3202 is an effective converter for most types of epoxy resin. It has a tendency to form complexes with atmospheric carbon dioxide, particularly in humid conditions, and can be formulated, adducted or otherwise reacted to inhibit amine blush.
