    PLATING RESIST MR-303F油墨

    PLATING RESIST MR-303F是適合用于部分鍍金用的遮蔽的單液性, 堿性剝離型抗鍍油墨.此外也適合用于ITO用的蝕刻油墨.

     
    PLATING RESIST MR-303F is one component, alkaline removable type Resist Ink developed for masking of partial Au plating.
    Moreover, it is possible to be used as etching ink for ITO.

    Main Feature
    1. Cured film has flexibility, and available for a flexible board and a rigid board.
    2. This ink has excellent resistance to Au plating( Electro-less),since the contamination to the plating solution
    is very small, control of the solution is easy.
    3. Possible to be used as etching ink for ITO.

    The above information obtained by actual measurement at our lab., and do not specified values.
    < Shelf-life > Main body: 6 months --- Stored in 25 deg.C or below (cool and dark place).
    Usage and handling precautions
    1. If dilution is needed due to viscosity variation during operation, dilute with exclusive reducer #70 within 5%.
    2. Drying should be done at the range of 100deg.C~130deg.C. Since drying time will vary based on s heat efficiency and ventilation capacity of used oven, please confirm your oven and set optimum condition.
    3. This resist can be used for general Ni/Au plating solution without any inconvenience.

    However, if it is used for special plating solution, it may cause the change in characteristics, depending on its composition. Please use it after checking fully.

    Elusion amount in Electro-less Ni Plating 

     

     ・Absorbance is high=Quantity of elution is large ・Absorbance is low=Quantity of elution is small Compared to Ni Plating new solution, absorbance peak which arise from elusion content from coated film can be confirmed at around 280nm for conventional product though, the peak can not be confirmed in MR-303F.
