High-temperature silicone sealers can stand up to temperature levels as high as 600 levels Fahrenheit as well as are immune to aging, vibrations and also shock. They are particularly formulated to secure and also encapsulate burner and industrial seals. High-temperature silicone is made to hold up against heats when healed, generally approximately 500 ° F, however some formulas are rated approximately 572 ° F.

WEICON SILICONE HT-300 HIGH TEMPERATURE

WEICON HT 300 adhesive and sealant is red, high-temperature
resistant (+300°C/+572°F), free of solvents, strong, and has
acetatecross-linking properties. It is resistant to weathering, ageing
and chemicals and is extremely elastic (breaking elongation of
approx. 300%).
HT 300 is particularly suitable for heat-exposed bonds and seals
and adheres very well to steel, aluminium, glass, ceramics and
many additional materials.
HT 300 can be used in industrial furnaces, flue gas systems,
heating installations, exhaust gas routing, heating cabinets and in
many additional areas.

– Resists to mechanical enforcement after curing,
– Acetoxy cure, RTV silicone,
– Will not crack, shrink or become brittle,
– One component.

APPLICATION AREAS
– Sealing and bonding applications in automotives,
– On heating systems and ovens for sealing / tightness,
– Sealing and bonding in stoves,
– Gaskets in pumps and motors,
– Sealing chimneys,
– Other bonding and sealing applications where parts must perform at
high temperatures.

ELRING Dirko Grey Silicone SEALANT

Dirko gray is a high-temperature sealing compound on a silicone base.
Dirko gray cures by reacting with the humidity in the air. The cured
sealing compound is permanently resilient. The product is characterized
by a very large range of applications.

Heat resistance:
The heat resistance of Dirko can be determined by simulating the extreme elongation behavior
of the sealing compound. Several key results of such tests are shown below. The elongation
simulated here does not occur in practice when used as a surface sealant.

Elastic modulus:

To determine the elastic modulus, the cured sealing compound is fixed in a clamping device
and is stretched 100%. The force required for this elongation is measured. The following
diagram shows the development of the elastic modulus (DIN 53504) as a function of the
pertinent temperature and time. The elastic modulus is shown as a percentage by comparison
to the value without temperature stress.

Storage:
Optimum storage conditions: cool (+5°C to +25°C) and dry
Minimum shelf life: 12 months in unopened containers

Victot REINZOSIL Gasket Maker

Material:
Anthracite coloured, solvent-free sealing, adhesive & coating compound
based on silicone. Once completely bonded, REINZOSIL is virtually
odorless

Properties:
This highly elastic universal sealing compound is resistant to mineral oils
and numerous synthetic oils, lubricants, petrol, diesel oil, greases, hot
and cold water, detergents, sunlight, ozone, and sea water.
REINZOSIL is suitable for continuous operation in the temperature
range between -50 °C and +250 °C (briefly up to 300 °C).
Hardness (softness) lies in the range of 30 to 35 Shore A.

Application:
Due to its special properties, REINZOSIL is used in the most varied
applications, e.g. as FIPG (formed-in-place gasket) for wet assembly, i.e.
for sealing small gaps under pressure as well as for cylinder liners in
piston machines, and also to compensate for extensive component
warping. Moreover, the compound is also used to seal constructional
fissures or cracks, and for seals that are subjected to considerable
relative movement.
Contrary to REINZOPLAST, the sealing layer is destroyed during
disassembly, and a new coating is required after the surfaces have been
cleaned.

The compound can also be applied to assembled components. In these
cases, after the sealing joint has been cleaned and degreased,
REINZOSIL is applied directly to the sealing gap, similar to the
procedures used in the building industry.

Storage period:
Unopened cartridges can be stored for about 12 months in a dry
environment (+5 °C up to 25 °C).
