Description
SERIES 140-15000 is a high quality pressure sensitive
adhesive used for the production of self adhering materials
made of paper and cardboard, rigid PVC, polycarbonate,
polyester （coated）, polyethylene and polypropylene （both
pre-treated, surface tension > 38 mN/m）, glass, metal and
industrial foams to self adhering items.
Materials bonded with SERIES 140-15000 are very difficult
to remove or even permanent depending on kind of the
substrate.
In general, the adhesive film is sufficiently light fast; however,
if placement in direct sunlight is expected, testing is
essential.
Bonded materials are resistant to water, diluted watery
acids and alkaline solutions, as well as to many mineral
oils.
Materials coated with SERIES 140-15000 can be stored for
a minimum of 1 year without any decrease of adhesive
strength, if covered with a suitable silicon release paper
and kept dry and dark at room temperature.
Application
Main application is screen printing process. Also possible
are roll and brush coating; for this a reduction of viscosity
with Series 10-02432 is necessary. When screen printing
use a medium shore squeegee （65 to 70 Shore）.
The optimal printing temperature is around 20°C / 70°F;
though, it’s suitable for application at higher room temperatures
such as: 20 -– 28°C or 68 – 82°F.
Mesh range: 18 - 43 threads/cm or 46 - 110 threads/inch.
As coarser the mesh size, as higher the adhesive strength.
So this is in relation to the film thickness （adhesive layer）.
Adhesive coverage is approx. 60 g/m² if applied to closed
surfaces s 36-100 Y PW mesh, depending on application
conditions.
As this glue is free of high aggressive solvents and water,
the most common emulsions and films can be used. Preliminary
tests are necessary by using indirect stencil materials.
SERIES 140-15000 can be dried at room temperature or
using conventional tunnel dryers for industrial production.
The adhesive must be compley dry and transparent
before a release liner is applied or further processing undertaken.
SERIES 140-15000 can be die-cut.
Back-lit windows should not be covered with adhesive as
this will change the light intensity.
Additional information
The suitability of the adhesive together with each component
i.e. substrate, ink, liner, adhesion partner etc. must be
tested before production parts are made. Special attention
should be paid to long term compatibility with component
materials. Also one must check the influences of the line
material and the state or nature of the substrate’s structure
or roughness. Silicone release agents, plasticizer migration
etc. must be checked for and ruled out before one continues.

Precautionary measures
Read material safety data sheet prior to processing.
The material safety data sheets according to OSHA form
contain indication of hazardous ingredients, TLV-level and
instructions for precautions when processing, handling and
storing as well as first aid. The information given in the MSDS
refers to processing as described in this technical leaflet. The
statements in our leaflets have been made to the best of our
knowledge and are given without any obligation. They serve to
advise our business associates, but it is absoluy necessary
to make your own printing tests under local conditions,
with regard to the intended purpose prior to starting the printing
job. In case of any doubts please contact our technical advisors.
