Applicable Base Polymer Properties

Elastomer modified epoxy resins are often used in epoxy resin formulations to increase flexibility, adhesion and fatigue resistance, particularly for adhesive, coatings, fiber sizing, binder and composites applications. An example resin is EPON Resin 58006, an adduct of diglycidyl ether of bisphenol A with carboxyl terminated butadieneacrylonitrile elastomers.

Resulting Properties

Non-Crosslinked Waterborne Elastomer Modified Epoxy (B) represents a case where a commercial epoxy resin dispersion is used to facilitate the dispersion of the other epoxy components. Here EPI-REZ Resin WD-512 is added to EPI-REZ Resin 3515-W-60, followed by addition of the elastomer modified epoxy resin. For this example, the rubber content is 7.5% by weight based on solids.

The source of this formulation is Momentive.
