Product Description
  • A hard, steel filled, high strength, wear resistant, thermally conductive, brushable tool and mold surface coat.
  • Used as a high performance mold or tool surfacing material and a mold or tool patching material.
  • Available in easy to use, two part pre-measured kits, which mix to a brushable, creamy consistency.
  • Reproduces exact surface detail and produces a hard, durable surface, that is both heat and chemical resistant

Advantages:
  • Has a very low shrinkage characteristic, which enables exact surface detail and dimension reproduction.
  • Used where moderate wear resistance is required.
  • Provides continuous high temperature service up to 350° F.
  • Highly resistant to mold release agents and mold cleaners.
  • Creamy, and spreads easily by brushing over a model or pattern.
  • Can be readily machined, drilled, tapped, or milled with conventional metal working tools.
  • Can also be used for changes and repairs in tooling.

Applications:
  • Foundry Patterns
  • Tracing masters
  • Molds and fixtures where high performance and exact detailing is required.
