Furan binders for casting sand KAO LIGHTNER

Furan binders hold a high market share in the field of labor intensive molding processes for high-mix, low-volume production, mainly machine castings.Furfuryl alcohol, the main ingredient in furan resins, is made from "non-edible biomass material" such as corn kernels and sugarcane chaff.This resin is made to react with a curing agent, such as organic sulfonic acid to cure the mold.

Features of KAO LIGHTNER

  • Because KAO LIGHTNER helps to create a stronger mold, it is possible to create a mold with less additives (generally 0.6-0.9% recycled sand), low resin viscosity, and superior sand fluidity and mold loading.
  • Because its pot life and mold release time can be broadly controlled, KAO LIGHTNER is suitable for a range of mold sizes and shapes.
  • There is little gas release from thermal decomposition during the pour, reducing the occurrence of gas defects.
  • Kao-Quaker offers products with a range of features, such as binders that reduce the amount of formaldehyde during the molding process and sulfurous acid gas during pouring.
  • We also have non-hazardous resins under the Fire Service Act, which have less restrictions on handling and storage.
  • We are working proactively to reduce our green house gas emissions, which contribute to global warming. 100% of the power used to manufacture our furan resin is renewable energy.

Super fast hardening furan resin (Non-flammable),
KAO LIGHTNER EF-1132

KAO LIGHTNER EF-1132 is a furan resin with the features of "fast hardening" and "improvement of working environment".

Fast hardening icon

Improvement of the work environment icon

Product features

(1) Fast hardening

  • Since the molding extraction time can be shortened, mold productivity can be expected to improve.
  • It is suitable for mold making lines where fast hardening characteristics are required.

(2) Improvement of the work environment

  • Sulfur remaining in the mold and in the reclaimed sand can be reduced, and SO₂ generation during pouring can be reduced.

Increased productivity

Because it is a fast-hardening type resin, stripping time can be shortened and the mold productivity is improved.

    Type of catalyst: US-3/C-21=38/2(5℃), US-3/C-21=12/28(35℃)
    Dossage of catalyst: 40% based on resin

Improvement of work environment (reduction of sulfur amount)

Since the amount of S (sulfur) in the mold can be reduced, SO₂ gas generation during pouring is suppressed.
