During the process of the anodizing, after the dyeing, during the boiling water
sealing treatment, the sulfate within the pore comes out together with
the dye, which can cause a declaring fault.
By pretreating with the ‘Dia Pre Seal’ before the high-temperature, sealing
treatment, it is a non-nickel, sealing, pretreatment agent that powerfully
suppresses the decoloring phenomenon when high-temperature sealing.
By responding to the RoHS certification and the environmental regulations,
the 4 biggest heavy metals (lead, mercury, chrome, and cadmium),
the substances that are regulated by the industry, and the nickel are
not contained at all.

special features

• When boiling-water sealing, the decoloration of the dyed material is powerfully suppressed.
• As it is a non-nickel, it is free from the harmfulness of nickel.
• As it suppresses the liquid ageing resulting from the mixture of the impurities, because the liquid life span is long, it is economical.
• There is no coloring contamination of the material that had been finishing treated in the silver color.
• There are no additional heating costs as the operation is performed at room temperature.
• It improves the reliability (the salt water resistance and the acid resistance) of the product that had been non-nickel sealing treated.

properties

• The external appearance: A light green liquid.
• The relative weight: 1.02 (20℃)
