EPIKURE™ Curing Agent 3253

 

 

Product Description

EPIKURE Curing Agent 3253, a tertiary amine, is tris (dimethyl amino-methyl) phenol. It is most often used as a co-activating accelerator for other epoxy resin curing agents including polyamides, fatty amidoamines, polysulfides and acid anhydrides. Secondary uses include catalysts for urethane elastomers, isocyanurate foams, epoxy homopolymerization and isocyanate trimerization.

 

Application Areas/Suggested Uses

  • Accelerator for epoxy resin curing agents
  • Catalyst for polyurethane elastomers
  • Catalyst for isocyanurate foams
  • Catalyst for isocyanate trimerization

 

Benefits

  • High reactivity
  • Low viscosity
  • Low vapor pressure
  • Good color

Safety, Storage & Handling

Please refer to the MSDS for the most current Safety and Handling information.

 

Please refer to the Hexion web site for Shelf Life and recommended Storage information.

 

Product will absorb moisture and carbon dioxide which may affect viscosity or create foaming when reacted with epoxy resins.

 

Exposure to these materials should be minimized and avoided, if feasible, through the observance of proper precautions, use of appropriate engineering controls and proper personal protective clothing and equipment, and adherence to proper handling procedures. None of these materials should be used, stored, or transported until the handling precautions and recommendations as stated in the Material Safety Data Sheet (MSDS) for these and all other products being used are understood by all persons who will work with them. Questions and requests for information on Hexion Inc. ("Hexion") products should be directed to your Hexion sales representative, or the nearest Hexion sales office. Information and MSDSs on non-Hexion products should be obtained from the respective manufacturer.
