Screen Printing Ink
Drying
Physically very fast drying,dries at 20℃ air temperature within
5-10min to be overprinted,at 50℃ in a tunnel dryer and stackable
within 20-30 sec.With high dryer capacity and good ventilation
provided,the drying temperature can be lowered to 40℃,for less
material distortion.If the SR is mixed with hardener PUH,the drying
time and block resistance of the ink is reduced.
Stress resistance
After proper and thorough drying,the ink film exhibits outstanding
adhesion as well as rub,scratch,and block resistance and is
weldable(SR 173 Black).SR colour shades have a high chemical
resistance to petrol(except SR170).Due to its high
pigmentation,Opaque White SR170 is unsuitable for moulding.Please
use White SR070 or SR270 instead.To achieve a maximum rub
resistance,the SR can be overvarnished with printing varnish SR910
or SR911.
Application
The high gloss Marastar SR is the ideal solution for printing high
quality labels,stickers,displays,industrial lettering of all
kinds,scales,and memebrane switches.Marastar SR is highly
block-resistant,considering that it is a high gloss ink,and
excellently suited for fast printing machines such as flat-bed
presses or fully automatic cylinder machines,but can also be used
for manual printing or on semi-automatic machines.SR can also be
processed with a spray gun,but preliminary trials are necessary for
this process.We recommend to filter the thinned press-ready ink(25
μm screen)before processing,as otherwise there could be bubbles in
the ink film.
