Core wash and mold paint FURANCLEAN

FURANCLEAN is a core wash and mold paint for high-quality casting and easy application.Kao-Quaker offers a range of unique products for a variety of applications, from aluminum castings to thick cast iron and cast steel castings.

Features of FURANCLEAN

  • Superior in preventing collapse of spheroidal graphite particles in ductile cast iron castings unique to furan resin molds.
  • We can propose products suitable for all applications, such as spraying, dipping and brushing.
  • Superior burn-on resistance and prevention of veining helps to reduce finishing processes.
  • We can propose a range of quick-drying, water-based core washes and mold paints.
  • Water-based core wash and mold paints for full-mold casting demonstrate a high resistance to burn-on and reduces residue defects in foam molds.

Quick-drying water-based coating agent FURANCLEAN    DF-900

FURANCLEAN DF-900 is a water-based coating agent with excellent performance on "quick drying" and "burn-on resistance".



Product features

(1) Quick drying

  • Excellent in quick drying, can shorten the drying time and simplify the drying equipment.

(2) Burn-on resistance

  • It has excellent burn-on resistance and can reduce the removal work of the burn-on part.
  • It has the same burn-on resistance as general alcoholic coating agents.

Drying speed evaluation example (1)

Because it can be applied with a low moisture content, it dries faster than general water-based coating agent products with the same penetration depth.In addition, it can be dried even with simple equipment such as panel heaters.

The FURANCLEAN OSK-7507NE reduces the three loads of "management", "work" and "cost".




Product features

(1) Japanese organic and specialization rules:
Not applicable

  • Since it does not fall under the japanese organic rule or the specialization rule, it can reduce the burden on compliance with laws and regulations.

(2) Reduction of coating film correction work

  • Since a uniform coating film is formed at the time of flow coating application, streaks after sagging is reduced and the load such as correction work is reduced.

(3) Reduction of usage

  • Low penetration characteristics can be expected to reduce the amount used.
  • Contributes to cost reduction by reducing the amount of expensive ethanol solvent used.

Merits of not falling under various laws and regulations

By utilizing OSK-7507NE, the following laws and regulations are not required*.
* Compliance with the japanese Fire Service Act is necessary
