EPIKURE™ Curing Agent 3200, 3223, 3234 & 3245

 

 

Product Description

EPIKURE™ Curing Agents 3200, 3223, 3234, and 3245 are unmodified aliphatic amines. They are used in a variety of applications including epoxy curing agents. Due to their tendency to form complexes with atmospheric carbon dioxide, particularly in humid conditions, they are most often formulated, adducted or otherwise reacted to inhibit amine blush.

 

Application Areas/Suggested Uses

  • Epoxy curing agents
  • Polyamides for inks and adhesives
  • Wet strength resins
  • Corrosion inhibitors
  • Oil and fuel additives
  • Chelating agents

 

Benefits

  • As members of the ethylene amine family, they lend themselves to a wide variety of chemical reactions and enduse applications.

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.

 

To preserve product quality and prevent discoloration, it is recommended that a nitrogen blanket be maintained on the headspace of an opened container and that storage / handling temperatures in excess of 50°C (122°F) be avoided. Spillage around the opening of the container from dispensing operations will form a crystalline residue. This residue is not soluble in the curing agent nor the resin, and certain measures should be taken to prevent it from contaminating the remaining contents of the container. The crystalline residue should be removed with a warm damp wash cloth PRIOR to re-opening the container for dispensing.

 

EPIKURE 3200, 3223, 3234, and 3245 Curing Agents should be kept in tightly closed containers in a cool, dry place. They will absorb moisture and carbon dioxide which will react. Avoid contamination with galvanized iron, copper, and its alloys.

 

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.
