ALBIDUR® EP 5340 A is a white, 40 % concentrated Dispersion of a high performance elastomer in a cyclo- aliphatic epoxy resin (EEC). It is used as a toughness modifier for rigid and brittle epoxy resin systems. The elastomeric component is a special silicone rubber which is distributed in the liquid resin as a very finely dispersed second phase.
Typical Applications
Like other ALBIDUR® resins, ALBIDUR® EP 5340 A is used in all applications where improved toughness of the cured resin is desired without sacrificing other properties, especially heat deflection temperature. Examples of possible uses for ALBIDUR® EP 5340 include
- Fibre-reinforced materials and composites
- Applications in electrical/electronic equipment, e. g. casting, potting, encapsulation
- Protective or decorative solvent-free coatings
- Structural adhesives
Benefits at a glance
In comparison to equivalent unmodified epoxy resins, cured ALBIDUR®-modified resins shows the following benefits
Unlike conventional toughness modifiers, ALBIDUR® does not significantly degrade physical properties at high temperatures. This is due to the unique properties of the elastomer and the complete phase separation between the elastomer phase and the resin matrix. Due to the low glass transition temperature of the elastomer (below -50°C) the toughness increase can be achieved at very low temperatures.
- Improved toughness (fracture energy, fracture toughness, impact resistance)
- Essentially unchanged deflection temperature as compared to unmodified resins
- Enhanced surface properties of the cured resin
- No significant reduction in hardness, thermal or chemical resistance, ageing or weathering stability
