Metallex Wärmestop Thermal protection Torch soldering Resin & ceramic Water-soluble 250 g tube
Metallex thermal protection paste – protection for resins and ceramics during soldering
Metallex thermal paste is a protective paste designed for torch soldering and brazing procedures in dental laboratories.
It is applied to sensitive areas to limit heat propagation and protect materials close to the soldering zone, including resins, ceramics, metals and prosthetic components that have already been finished or adjusted.
Heat protection Helps insulate sensitive areas during soldering
Resin & ceramic Protects materials exposed to thermal risk
Easy rinsing Water-soluble and grease-free paste
Tube dosing Targeted application according to the area to protect
A heat-stop paste to secure soldering procedures in the laboratory
During torch soldering, heat can spread to neighbouring areas and cause deformation, marks or surface damage on sensitive materials.
Metallex Wärmestop paste forms a temporary thermal barrier around the area to be protected. It allows the dental technician to better control the impact of heat during brazing procedures.
Its 250 g tube packaging makes direct application easier in the laboratory, with precise dosing according to the size of the component and the intensity of heating.
Limit heat propagation
Metallex is used as a thermal protection paste during soldering and brazing procedures.
- Helps block heat diffusion towards sensitive areas.
- Protects materials close to the flame.
- Reduces the risk of deformation during soldering.
- Makes it possible to work closer to prosthetic areas that are already finished.
Protect fragile materials
This paste is useful when the component includes heat-sensitive materials or areas that have already been fitted or adjusted.
- Protection of resins during nearby soldering.
- Protection of ceramics and aesthetic areas.
- Protection of certain metal or precious metal surfaces.
- Reduction of rework caused by thermal damage.
Applications in the dental laboratory
Metallex thermal paste is used for procedures where one area needs to be soldered while another must remain protected from heat.
- Torch soldering on dental metal components.
- Protection of resins during repair or assembly work.
- Protection of ceramics close to the heating zone.
- Protection of metals and precious metals during certain procedures.
- Brazing work requiring a localised thermal barrier.
The paste does not replace flame control or correct component preparation. It complements the soldering protocol by limiting thermal transmission towards the protected areas.
Protection up to approximately 4,000 °C
Product sheets indicate heat protection against soldering heat up to approximately 4,000 °C.
- Suitable for torch soldering and brazing work.
- Localised thermal protection of sensitive areas.
- Reduction of the risk of marking or deformation.
- Use according to protocol and heating duration.
Thickness to be adapted according to heating
The paste thickness should be adapted to the heat intensity and the area to be protected.
- Apply a sufficient layer to sensitive areas.
- Increase the thickness if heating is more intense.
- Protect the entire surface exposed to thermal risk.
- Remove the paste after cooling and cleaning.
Benefits for the laboratory
- Fast thermal protection before soldering.
- Targeted application thanks to the tube format.
- Water-soluble for simple cleaning.
- Grease-free to help limit greasy residues on components.
- 250 g packaging suited to regular use.
Metallex allows the laboratory to secure soldering procedures close to sensitive areas, with simple and fast implementation.
Benefits for prosthetic components
- Limits heat-related surface damage.
- Helps preserve resins during repairs.
- Protects ceramics close to the brazing area.
- Reduces the risk of deformation of sensitive materials.
- Facilitates clean reworking after soldering.
The result depends on the applied thickness, heating duration, distance from the flame and compliance with the soldering protocol.

Instructions for laboratory use
The paste should be applied before soldering to the parts that need protection. The area to be brazed must remain accessible and prepared according to the laboratory’s usual protocol.
Before soldering
- Identify the sensitive areas to protect.
- Apply Metallex to resins, ceramics or exposed metal areas.
- Adapt the thickness according to the expected heat.
- Keep the exact soldering area free so as not to interfere with brazing.
After soldering
- Allow cooling according to the laboratory protocol.
- Remove the protective paste.
- Rinse residues with water.
- Inspect the protected surface before finishing.
Tips for effective component protection
Thermal protection depends on the amount of paste, proximity to the heating zone and duration of exposure to the flame.
- Apply the paste before starting heating.
- Cover the entire area to be protected, without leaving any sensitive surface exposed.
- Do not apply paste to the area where the solder must flow.
- Renew or increase the protection thickness if the heating protocol is long.
- Clean thoroughly after cooling to inspect the surface condition.
Good flame control remains essential: the paste protects sensitive areas, but should not be used to compensate for heating that is too aggressive or poorly directed.
Thermal paste, flux and anti-flux: do not confuse them
| Product | Role | Application area |
|---|---|---|
| Metallex thermal paste | Protects materials from heat | On sensitive areas to be insulated |
| Soldering flux | Promotes solder flow | On the area to be brazed |
| Anti-flux | Prevents solder from spreading | Around the area that must not be wetted |
A practical product for soldering close to sensitive areas
Metallex thermal paste is particularly useful when the laboratory needs to work with a torch without unnecessarily exposing a resin, ceramic or already finished area.
It helps reduce the risk of deformation, marking or surface alteration, while remaining easy to apply and clean after the procedure.
The 250 g tube allows regular use at the soldering workstation, with dosing adapted to each clinical or prosthetic situation.

FAQ – Metallex thermal protection paste
What is Metallex thermal paste used for?
Metallex thermal paste is used to protect sensitive areas during soldering or brazing work.
It helps limit heat propagation towards resins, ceramics, metals or already finished areas of the prosthesis.
On which materials can it be used?
Product sheets indicate protection for resins, ceramics, metals and precious metals.
The product should be applied only to the areas to be protected, leaving the exact area where soldering is to be performed free.
How should Metallex be cleaned after soldering?
After cooling, the paste can be removed and then rinsed with water.
Its formulation is indicated as water-soluble and grease-free, which makes cleaning easier before inspection and finishing of the component.
What thickness should be applied?
The thickness depends on the expected heat, soldering duration and proximity to the area to be protected.
It is recommended to cover the entire sensitive area with a sufficient layer, adapting the amount to the work being performed.
Does the paste replace soldering flux?
No, Metallex is a thermal protection paste. It is used to protect against heat, not to promote solder flow.
Soldering flux should be used on the area to be brazed if required by the protocol, while Metallex is applied to the areas that need to be insulated from heat.
What does the delivery include?
The delivery includes 1 tube of Metallex thermal paste.
The packaging is 250 g, suited to thermal protection work in the dental laboratory.
