EPIKURE™ Curing Agent 3300

 

 

Product Description

EPIKURE™ Curing Agent 3300 is a very low viscosity, light colored cycloaliphatic amine curing agent for use in formulating heat cured epoxies. Isophorone diamine can be blended with other amine-based hardeners or with epoxy accelerators to achieve ambient curable epoxy compositions. As a sole curing agent, EPIKURE Curing Agent 3300 can yield epoxy systems with relatively high heat distortion properties when properly cured.

 

Application Areas/Suggested Uses

  • Resistant to blush or “sweat-out”
  • Low color
  • Good physical properties
  • Good chemical resistance

 

Benefits

  • Laminates
  • High build glaze, sealer or gel coat
  • Light color castings
  • Heat curable binders for textiles

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 the product quality and prevent product discoloration, it is recommended a nitrogen blanket be maintained on the head space of an opened or in-use container. Spillage around the opening of the container from dispensing operations will form a white crystalline residue. This residue is not soluble in the curing agent or the resin, and certain measures must be taken to prevent contamination of the remaining container contents. Remove all signs of crystalline residue by wiping with a warm damp wash cloth prior to opening the container for dispensing. Wear proper personal protection at all times.

 

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.
