HM-242 is pressure sensitive hot melt adhesive for labels. With great tack and holding power, high
peel strength, great heat-resistance performance, excellent resistance to oil-bleeding and ageing,
HM-242 has good heat effect.

Its adhesion performance will be affected by substrates, release paper and application environment, so
trial run is necessary to determine whether the adhesive is suitable.
There should be no dust or oil on the surface of substrates and release paper, also the
substrates and release paper should be treated to constant temperature and humidity before
Application methods: roller or spray
Operating temperature: the 150-170ºC, is recommended in the glue viscosity can be adjusted by the
temperature of summer appropriate Down 5-10 ºC, raised 5-10 ºC in winter.
Application-temperature of the labels between +5°C and 50°C,Temperature resistance of the applied
label from -20°C to +60°C
Packaging and Storage:
Shelf Life: 12 Months in dry and cool environment
Packaging: 20kg/Carton, About1kg/cake, Wrapped with fusible films
The residual adhesive can be rubbed off by wooden shovel before it is totally cooled.
Cooled glue can
be cleaned with specialized detergent. Applicators can be cleaned with mineral oil at 120ºC,
then purged with hot melt adhesive.
Don't mix the product with other adhesives.
Keep the adhesive containers covered to avoid dust or contamination.
Stop heating if you don't use it for a long time to avoid the carbonization of the adhesive
Wear safety glasses, safety gloves and safety clothes when using hot melt adhesive to avoid scald.
