New one-part
warm applied
polyurethane
sealant
Reactive Warm Melt is a new onepart
warm applied Polyurethane sealant
which is available in the UK exclusively
from Thermoseal Group.
This recent addition to the HB
Fuller range of edge sealants has, says
Thermoseal, many advantages over
other insulated glass unit sealants
available on the market, including:
• application temperature is 110-
120°C compared to traditional hot
melts with application temperatures
of 170-195°C. This means that
there is far less heat conducted
through the spacer bar and glass.
This greatly reduces the level of
deflection in units;
• the unique character of this product
means sealant depths as low
as 3mm are achievable without
compromising the quality of the
sealed unit. This can help towards
gaining higher Window Energy
Ratings;
• this sealant has a full moisture-sensitive
cross-linked curing system
which provides a strong chemical
bond to the glass and spacer system.
This is unlike all other butyl
based hot melt sealants which
rely on a purely physical bond
to the glass and spacer system;
• once cured, Warm Melt is an elastomer
which provides a solid seal
that will not move or slip in the
presence of heat;
• Warm Melt provides the same production
and handling benefits as
those of traditional hot melt
sealants.
Mark Hickox, sales director at
Thermoseal Group says: “We have
already spoken to many customers who
are thrilled that this sealant will help
to improve Window Energy Ratings,
but perhaps one of the most promising
areas for application of Reactive
Warm Melt will be in the production
of conservatory roof glass. This glass
is exposed to high surface temperatures
which can cause standard Hot
Melt’s to slump dramatically, whereas
Warm Melt will not.”

Reactive Warm Melt has been
tested to EN1279 parts 2 and 3 with
metal and foam spacer systems.
It is supplied in 20ltr and 200ltr
drums which will fit most drum
loading hot melt robots or small
drum dispensers.
