ResinRock XL5

Resin-Fortified, Increased-Expansion Die Stone

ISO Type 5

RESINROCK XL5 has the same smoothness and high abrasion resistance you’ve come to appreciate in ResinRock. However, this ISO Type 5 die stone gives you increased expansion to compensate for shrinkage of vinyl polysiloxane and other rubber-based impression materials.

Available in four colors: green, blue, pink and ivory. Pink, blue, and green provide excellent contrast to casting waxes. The neutral tone of ivory complements all ceramic materials.


  • Ideal for use with rubber-based impression materials which may contract over time
  • Increased setting expansion of 0.20%
  • Resin-fortified for advanced abrasion resistance
  • Smooth, dense surface for superior detail reproduction
  • Thixotropic, creamy mix stacks and vibrates easily into impression

Please note the use of Gypsum Hardener is not recommended with this product
