DEKYsyl MS Technical Data Sheet
TECHNICAL DATA SHEET
DEKASYL MS-5
HIGH TACK ADHESIVE & SEALANT
PRODUCT
Dekasyl MS-5
is a MS Polymer based adhesive with a high green strength and is suitable for making elastic
constructive joints. Due to its high green strength clamping times can often be reduced or clamps are not needed
anymore.
Dekasyl MS-5
can also be used as sealant, if similar material (similar stiffenesses) are joined together,
or if mechanical fastening methods are used.
APPLICATIONS
Elastic bondings and sealings in e.g. bus-, train-, caravan-, camper and truck construction.
Bonding of windows in e.g. busses and trains.
Bonding of corner profiles of aluminium or polyester on trailers.
Bonding of polyester parts on metal frames.
FEATURES
Solvent-, isocyanate- and PVC free.
Very good UV-resistance and ageing properties.
In general good adhesion on several substrates without the use of a primer.
Permanent elastic within temperatures from –40°C till +120°C.
Neutral, odourless and fast curing.
Paintable after skin forming (wet on wet); this will in general not influence the curing speed.
Paint compatible with most industrial paint- or lacquer systems, both alkyd resin and dispersion based
(due to the large scale of different types of industrial paints a paint compatibility test is recommended!)
ADHESION
In general
Dekasyl MS-5
adheres well without primer on clean, dry, dust- and grease free substrates of
aluminium, stainless steel, galvanised steel, zinc, copper, brass, powder coated metal, most lacquered metal
surfaces, glass, PVC, polyester (GRP), painted and lacquered wood, etc. No adhesion on untreated
polyethylene, polypropylene and teflon. In those cases where due to great thermal or physical loads, especially
under wet conditions, high adhesion demands are needed, the use of an adhesion promotor is recommended.
For not mentioned substrates and additional information consult Dekalin
.
METHOD OF USE
Dekasyl MS-5
can easily be extruded with a hand- or air pressure gun at temperatures b5°C and 35°C.
In sealing applications
Dekasyl MS-5
should be tooled or smoothened within 12 minutes (at 20°C/50%R.H.) with
a spatula or putty knife, occasionally moistened with a mild soap solution. Avoid soap solution penetrating
between joint sides and sealant, because this will create loss of adhesion.
In bonding applications the substrates
have to be assembled within 15 minutes (at 20°C/50%R.H.) after applying
Dekasyl MS-5
. The higher the
temperature, the shorter the open time will be! In general an adhesive thickness of 2 mm is recommended if
similar materials (similar stiffenesses) are bonded. The larger the difference in thermal expansion is, the thicker
the adhesive bead should be. For more details Dekalin should be consulted.
At a temperature of 20°C and a
relative humidity of 50%
Dekasyl MS-5
can be painted with the most industrial paints already 10 minutes after
application. Best adhesion of paint coats is generally obtained if painted within 4 hours after applying
Dekasyl
MS-5
.
Cleaning tools or removing uncured residue of Dekasyl MS-2 can be done with a clean colourless cloth,
wetted with e.g. acetone or MEK. It is recommended to make a trial first to check possible attack of the substrate
by these cleaners.
