APPLICATIONS
DOW CORNING 1205 Primer is used to
improve both the quality and speed of
adhesion development of room
temperature vulcanizing silicone sealants
to various substrates, particularly plastics.
APPLICATION METHOD
Surfaces to which primer will be applied
should be thoroughly cleaned using an
appropriate solvent on a coarse lint-free
cloth. Please ensure that the cleaning
solvent selected does not affect any plastic
surfaces. Surfaces should be wiped dry
immediately after cleaning. Please consult
the relevant product information sheet for
recommendations on cleaning products.
Prior to application, sufficient primer
should always be transferred to a working
container and not used directly from the
original container. Do not decant more
primer than can be used in one hour. This
procedure will prevent wastage and
contamination of the bulk material.
DOW CORNING 1205 Primer should be
applied using a lint-free cloth to form a
thin film on the surface of the substrate. If
more suitable, a brush may be used to
apply this primer, but care has to be taken
to avoid over application.
After application of the primer, brushes
and working containers should be cleaned
with an appropriate solvent. Any unused
primer that has been decanted should be
discarded in an appropriate manner and
not returned to the original container.
