EPIKURE™ Curing Agent 3292-FX-60

 

 

Product Description

EPIKURE™ Curing Agent 3292-FX-60 is a high molecular weight amine adduct supplied at 60 percent nonvolatiles in butanol/xylene. It is specifically designed for use in two-package, air-dry epoxy coatings. When combined with a liquid epoxy resin (WPE = 190), such as EPON™ Resin 828, EPIKURE 3292-FX-60 will produce cured coatings at temperatures as low as 20 °F.

 

Application Areas/Suggested Uses

  • Industrial maintenance primers, midcoats, and topcoats
  • Marine coatings for immersion service in fresh and salt water
  • Zinc-rich primers
  • Methanol resistant tank coatings
  • Concrete floor coatings
 

 

Benefits

  • Cures at temperatures as low as 20 °F
  • Outstanding solvent resistance
  • Water, mineral acid, and corrosion resistance
  • Rapid film hardness development
  • Adhesion to properly prepared metal surfaces
  • High gloss and good color

General Information

EPIKURE Curing Agent 3292-FX-60 , when combined with liquid epoxy resin, such as EPON Resin 828, will produce coatings possessing a remarkably broad range of performance properties. A unique combination of chemical, water, and corrosion resistance can easily be obtained from coatings based on EPIKURE Curing Agent 3292-FX-60 and EPON Resin 828.

 

The most outstanding feature of EPIKURE 3292-FX-60 Curing Agent is that it allows the formulation of coatings which will form tough, high performance films at application temperatures as low as 20 °F. The coatings obtained are glossy, free of amine sweat-out and resistant to high humidity conditions. High reactivity coupled with the high molecular weight of EPIKURE 3292-FX-60 provides very fast cure responses at low temperatures. Although excellent properties are obtained at low temperatures, maximum resistance to solvents is rapidly achieved following exposure to temperatures above 60 °F. Epoxy resins of higher molecular weight (WPE approx. 500), such as solutions of EPON Resin 1001F, can be used successfully with EPIKURE 3292-FX-60 Curing Agent. Lower cost formulations are possible in applications that do not require maximum solvent resistance. Coatings formulated with an epoxy solution such as EPON Resin 1001-X-75 and EPIKURE 3292-FX-60 possess good humidity and salt spray resistance.

Formulating

 

When formulating for low temperature applications, solvents that have slow evaporation rates and are appreciably miscible with water should be avoided. However, for improved flow and leveling, small quantities of solvents such as 2-butoxyethanol can be used. Recommended solvents are glycol ethers, alcohols, and ketones. Use of any additional aromatic solvent should be limited.

 

Pigmentation can be accomplished satisfactorily in either the epoxy resin or curing agent portion. When dispersing pigments in EPIKURE 3292-FX-60, avoid excessive heat to minimize solvent loss and exposure to solvent fumes. EPIKURE 3292-FX-60 is an excellent pigment wetter allowing very fast dispersion times for most common pigments.

 

A combining ratio of 62.5 percent liquid epoxy resin (WPE = 190) and 37.5 percent EPIKURE 3292-FX-60 Curing Agent, based on resin solids (BOS), provides the best overall properties. Increasing the curing agent level increases solvent resistance at the expense of water and acid resistance.

 

Reactive diluents such as HELOXY™ Modifiers 8, 505 and 48 and NC-5131 are not recommended for low temperature applications. However, they may be employed at levels up to 15 percent based on total resin nonvolatiles in room temperature applications.

 

Dimethylaminomethylphenol accelerators such as DMP-302 and DMP-102 are not recommended, since they reduce the water, acid and corrosion resistance of the coatings. Accelerators, such as bisphenol A, can be used, and levels up to 8 phr based on curing agent nonvolatiles have demonstrated no adverse effects on coating performance. When using accelerators, careful attention should be given to their effect on pot life. Coatings based on EPON Resin 828 and EPIKURE 3292-FX-60 Curing Agent have a typical pot life of 2 to 4 hours, depending on the percent resin nonvolatiles of the formulation. Accelerators will shorten this time considerably.

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.

 

 

EPIKURE 3292-FX-60 Curing Agent should be stored in tightly sealed, lined containers in a dry location at normal room temperatures.

 

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.
