Simson Primer M
The Simson Industrial Special Range consists of a range of high tech. quality products, especially developed for
industrial applications.
PRODUCT
Simson Primer M is a “wash primer” for the improvement of the adhesion on closed substrates of several specific
Simson products, based on Silyl Modified Polymer (SMP). Consult the technical information leaflet of the
particular product.
APPLICATIONS
■
Pretreatment of plain aluminium, steel, copper and brass surfaces.
■
Pretreatment of powder coated metals.
■
Pretreatment of lacquered metals (first make a test on the substrate to check possible effects).
■
Pretreatment of ceramic coated glass.
■
Pretreatment of polyester (GRP).
■
Pretreatment of ABS.
■
Pretreatment of PVC.
FEATURES
■
Fast drying; approximately 5 minutes.
■
Easy to use as “wash primer”.
■
Efficient in use.
METHOD OF USE
The substrates should be clean, dry, dust- and grease free. Keep the packaging well closed until the moment of
use. Simson Primer M can be used directly from the original packaging, provided primer contamination and
viscosity increase is prevented. Therefor make two openings in the aluminium seal at the top of the bottle. Take
care to close the bottle after use. Simson Primer M is used as a so-called “wash primer”. The primer should not
be applied in too thick a coat. Firmly rub the surface by means of a clean, colour free cloth or tissue paper, wetted
with Simson Primer M. In this way the surfaces will be cleaned and primed in one operation. After a drying time of
approximately 5 minutes (solvent should be evaporated) the sealant or adhesive can be applied. Best results are
obtained when the bonding/sealing will be realised within 6 hours after applying of Simson Primer M. Therefore do
not apply more primer than can be sealed within 6 hours. Avoid contact with the primed surface, because greasy
fingers can cause a bad adhesion.
Note 1: Simson Primer M should not be applied on those areas which have to be painted afterwards, due to the
bad paint compatibility of Simson Primer M. In this case only apply Simson Primer M on that area where the
sealant or adhesive will be applied by use of e.g. masking tape (however it is possible to remove residues of
Simson Primer M afterwards from the cleaned surfaces by use of e.g. Simson Cleaner 14, Simson Liquid 1 or
Isopropylalcohol (IPA)).
Note 2: If a surface is strongly contaminated clean first with e.g. Simson Cleaner 14. It is recommended to make
a trial first to check possible attack of the substrate by Simson Cleaner 14.
