● Features
- If adsorbed films are formed by temperature difference of aqueous solution, PAG films are formed on treated surfaces when red heat metal is soaked in GCOL-A solution and forming of vapor blanket is restrained. As a result, cracking does not occur and deformation is reduced because uniform heat is extracted and uniform hardening is performed even on complex structures.
- Low risk of fire because both diluted and undiluted chemicals are non-flammable so it is environmentally safe.
- It does not deteriorate because it is semi-permanent use possible by refilling.
- Enables the attainment of an ideal cooling curve, through the control of concentration, fluid temperature and flow speed.
- Concentration can be measured by saccharometer and is easily controlled.
- Prevents problems usually associated with uniform quenching because of its excellent antifoaming power.
- Enables tempering without prior degreasing.
