High Capacity Solder Mask Stripper

MaskStrip (RD-85) MaskStrip (RD-85) is designed to remove uncured UV and thermal solder mask from printed circuit boards and screens. It contains no methylene chloride, other chlorinated solvents or aromatic organic compounds.

MaskStrip (RD-85) is fully water rinsable and does not affect laminate or metal plating. With proper dilution, rinse waters may not require special treatment. MaskStrip (RD-85) will not attack plated metals, so spent solutions will have no heavy metal content. Screening frames and fabrics will not be harmed with this process.

MAKE-UP:
MaskStrip (RD-85) is used at full strength and at room temperature.

OPERATION:
Circuit boards and screening equipment should be immersed from 5 minutes to one hour, depending on the thickness, type of mask and age of deposit. Some solder mask formulations will dissolve completely. Others may require additional scrubbing or spray rinse to completely remove all material. Water rinse with spray or agitated immersion.

Optimum life and effectiveness is achieved by using a two tank system where the second tank of MaskStrip (RD-85) functions as a clean rinse before the final water rinse. When the first tank becomes heavily loaded it is replaced by the contents of the second tank, and the second tank is refilled with fresh MaskStrip (RD-85).

Do not allow water to contaminate MaskStrip (RD-85), as this will shorten bath life significantly.

EQUIPMENT:
MaskStrip (RD-85) can be stored in polypropylene, polyethylene, or stainless steel. Tanks should be covered to keep out water spills.

SAFETY:

MaskStrip (RD-85) contains a non-aromatic solvent blend. Avoid contact with skin and eyes. Wear protective clothing, and avoid breathing vapors. Consult Material Safety Data Sheet for further information.

DISPOSAL:
Dispose of in accordance with Federal, State and local regulations. Contact your RD Chemical representative for further information.

PACKAGING:

MaskStrip (RD-85) is available in 5 gallon pails and 55 gallon polyethylene drums.
