Description
1. DIRECTIONS
• For small runs and service applications, the easiest way to apply PLASTIK 70 is from anaerosol
can. Spray from a distance of 20 to 30 cm on the dry and degreased surface. As
pre-cleaning of PCB’s, we do recommend the use of KONTAKT PCC to remove greases,
dirt and flux residues. When finished spraying, clean the aerosol valve by turning the can
upside down and pressing the button until only propellant escapes.
• For serial production runs, PLASTIK 70 in bulk can be applied by brush or by dipping. For
spraying, two parts per volume PLASTIK 70 is diluted with up to one part of THINNER
FOR PLASTIK 70. The precise mixing ratio must be determined by trials with the
equipment concerned.
• For dip coating it is also necessary to fix the immersion time and the withdrawal speed.
The faster the removal from the bulk, then thicker the film will be. Dipping baths have to
be carefully protected to ensure no entrapment of conductive stuck-on residues.
• PLASTIK 70 contains solvents like ethyl acetate and butyl acetate. Printed circuit board
materials and electronic components generally have a good compatibility with these
solvents. In case of plastic surfaces (e.g. housings) a compatibility test is always
recommend. It is necessary in particular, to test its suitability for plastics susceptible to
stress cracking (e.g. polycarbonate).
• PLASTIK 70 contains flammable solvents and hence when working with the product,
make sure there is good ventilation in the workplace. Remove all possible ignition
sources.
• A safety data sheet (MSDS) according to EU directive 91/155/EEC and amendments is
available for all CRC products.
