EPIKOTE™ Resin 3515-W-60

 

 

Product Description

EPIKOTE Resin 3515-W-60 is a moderate viscosity, non-ionic, aqueous dispersion of a bisphenol A epoxy resin. EPIKOTE Resin 3515-W-60 is supplied at typically 60 percent non-volatiles and is mechanically stable. No organic solvents are present.

 

Application Areas/Suggested Uses

EPIKOTE Resin 3515-W-60 offers a solvent-free approach to the formulation of for example:

  • Industrial textile binders of fibre finishes
  • Adhesives
  • Coatings and electrical dip coatings
  • Varnishes.

It can also be incorporated into formulations which are traditionally water-based and which require good strength and outstanding chemical or water resistance. EPIKOTE Resin 3515-W-60 is used to modify polymer lattices, especially those containing sufficient amine or carboxyl functionality to react with available epoxy groups.

EPIKOTE Resin 3515-W-60 can be cured with many of the same curing agents that are used with liquid or solution epoxy resins. Curing agents most conveniently employed are those which are water soluble or dispersible and which are stable in an aqueous medium. Examples of such curing agents include dicyandiamide, substituted imidazoles, aliphatic and aromatic amines and various EPIKURE Curing agents.

When applied at room temperature, EPIKOTE Resin 3515-W-60 coalesces to form a clear, continuous, tacky film after evaporation of the water.

 

Benefits

  • High epoxy functionality
  • Water reducible, providing wide latitude for viscosity reduction
  • Imparts good chemical and water resistance properties
  • Compatible with most synthetic polymer lattices
  • Curable with most water soluble curing agents

Safety, Storage & Handling

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

 

EPIKOTE Resin 3515-W-60 should be stored in tightly sealed containers in a dry location at temperatures between 10 and 38°C. Under these conditions the shelf life should be a minimum of one year from date of certification. Elevated temperatures or freezing conditions will accelerate particle settling which will require re-dispersion with moderate agitation. Do not allow the product to freeze.
