Remix each of the 2 components (parts A and B) every time before using.

1. Manually
1.1 - Catalysis
BLUESIL RTV 8352 LV A&B should be mixed thoroughly in proportions of 100:100 by weight, by hand or with an electric stirrer rotating at low speed, to prevent the entrapment of air into the mix

1.2 - Degassing
The mixture of the two components should be degassed to remove air bubbles which would reduce the mechanical and dielectric properties.
Degassing is generally performed in a vacuum of 30 to 50 mbars for about ten minutes, releasing the vacuum twice in the chamber.
Degassing will be quicker in a container with a large diameter to height ratio.

2. Mixing machine
Equipment consisting of two metering pumps enables the control of volumetric flow rates of parts A and B which are thoroughly mixed when they go through a dynamic mixing head or a static mixer.

3. Preparing of materials and pouring
BLUESIL RTV 8352 LV A&B can be poured on to metals, glass, laminates or moulded articles containing organic resins or silicones, or on all other materials.
The following procedure is recommended:

  • Clean the surfaces and remove grease with the appropriate solvent. Silicone elastomer surfaces should first be roughened, if possible, by rubbing with sandpaper.
  • Slowly pour the degassed BLUESIL RTV 8352 LV A&B mixture at the lowest point of the volume to be filled, to prevent the formation and entrapment of air bubbles.

The container should not be filled completely, to allow the RTV to expand at working temperatures.

4. Curing
At a temperature of , BLUESIL RTV 8352 LV A&B cures in approximately 8 hours.
Curing can be accelerated by external heat, and the higher the temperature the faster curing will be. For example, at 120 °C the product cures in about 1 hour.

5. Remarks
Curing of the RTV may be inhibited by contact with certain materials

  • Natural or synthetic rubbers vulcanised with sulphur derivatives.
  • RTV catalysed with metallic salts.
  • PVC stabilised with tin salts.
  • Epoxies catalysed with amines.

In case of doubt, a test should be made by pouring the mixture of the two components on to a small area of the object. It is also advisable to keep degassing apparatus exclusively for this type of RTV, as use with other substances might contaminate it and affect curing of BLUESIL RTV 8352 LV A&B.
Ensure that the packaging is hermetically sealed again each time it is used.

BLUESIL RTV 8352 LV A&B is a two-component silicone elastomer which cures at room temperature by a polyaddition reaction. The curing can be accelerated by heating.
BLUESIL RTV 8352 LV A&B is supplied in the form of a viscous liquid which is transformed, after mixing parts A&B and then curing, into a strong, elastic material.






  • Dissipation of calories (encapsulation).
  • Low viscosity (easily refilled).
  • Advantageous mixing ratios (1/1):
  • Unaffected by inaccurate dosage.
  • Usable in two-component machines.
  • Fast curing time.

Additives range: Accelerator BLUESIL ACC PA 39 and retarder BLUESIL RTRD PA 40.


Coating and encapsulation in electro-technical and electronics applications.
