Product Description

  • tough-elastic with shore hardness of approx. A 98 / D 54
  • high rebound elasticity
  • good flowabilityfast curing
  • high tensile strength and high abrasion resistance

Characteristics and Advantages

  • Insensitive to moisture
  • Good abrasion resistance
  • good impact resistance and tensile strength
  • good chemical resistance
  • good temperature resistance
  • dyeable with Biresin® Farbpasten
  • with Biresin® U1419L for increased potlife (see separate Technical Data Sheet )


  • That shore hardness of around A 98 offers highest abrasion resistance of core boxes also opposite the shootingnozzles due to the high rebound elasticity. Biresin® U1419 with its 6-7 min potlife is suitable forsmall core boxes and short demoulding times
  • Casting of abrasion and impact resistant mouldings and tools, e. g. core boxes
  • Casting of tough-elastic coatings


As casting resin for the foundry industry: coloured-transparent
As vacuum casting resin: yellowish-transparent
