Bond It HT30 High Temperature Heat Resistant 300° Silicone Sealant Adhesive 310ml

Description:
A ready to use, one component, acetic curing heat resistant silicone sealant.

Benefits:
w Non sagging.
w High Temperature resistance up to 300oC.
w Mildew resistant.
w UV resistant and weatherproof.
HT30 has been specifically designed for high temperature use.
After curing HT30 will resist temperatures of +250o
C permanently
and up to +300o
C for short periods.

Uses
Bond It HT30 is generally used for sealing joints which are exposed
to high temperatures, i.e. connections on ovens, heating systems,
machines, car bodies (vicinity of engines), etc. HT30 does not
loose it’s sealing properties under extreme conditions. Not
suitable for use within 1 metre of wood burning stove flues.
HT30 can be applied to glass, ceramic tiles, enamel, epoxy paint
and polyester. It can also be used with polyamides, ABS, metals
and polyester in immersion or humid heat, however, a primer may
be required.

Preparation
Ensure all surfaces or joints are clean, dry and free from grease, oil
or any other contaminants that may hinder adhesion. Primer may
be required on certain absorbent surfaces.

Application
Apply using a standard sealant gun with the nozzle cut at an angle
of 45°, and to an opening slightly larger
than the joint to be sealed. Alternatively
HT30 can be tooled with a finger, thin piece
of wood dipped in a tooling liquid or Bond
It SEALANT APPLICATOR TOOL. Avoid any
contamination or mechanical pressure of
the sealant before skinning process has completed. Cover sealant
if it is necessary.
Apply HT30 to one of the two parts to be assembled, then bring
the two parts together. The sealant will start to cure on contact
with atmospheric humidity. After 3 to 5 minutes exposure to air, it
is no longer possible to “rework” the product. Curing can be
accelerated by increasing temperature up to a maximum of +150oC
dry heat.

Limitations
HT30 is not suitable for use with aquarium building. HT30 can also
cause stains around joints on marble, sandstone and other
extremely absorbent substrates if they are not treated carefully
with a primer. HT30 cannot be over painted, therefore substrates
to be painted must be kept free of sealant. During the curing
process small quantities of acetic acid are released which could
attack certain kinds of metal but also alkaline substrates.

Colour
HT30 comes in 2 colours: black and red.

Container Size
310ml plastic cartridge.

Shelf Life
18 months from date of manufacture when stored in original
unopened cartridges.

Storage Conditions

+30oC.

Disposal of Containers
Do not leave empty containers where residue could be harmful to
children, animals or the environment. Remove any containers to a
central disposal point in accordance with local regulations. Health & Safety
Please refer to separate material safety data sheet for full
handling, use and storage instructions. Keep out of reach of
children. It is the users responsibility to determine suitability for
use. If in doubt contact our Technical Department for advice.
Note: this information is for general guidance only, since site conditions
