SILBIONE RT GEL 4725 PM B may be stored at a temperature between -10 °C/ 14 °F and 30 °C/ 86 °F for up to 3 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.

SILBIONE RT GEL 4725 PM B

SILBIONE RT GEL 4725 PM A&B is a low density silicone premix, which once mixed with additives will transform into a soft and elastic gel.

This multi-components system cures at room temperature, the polyaddition reaction can be accelerated by heat.

Remix each of the two components (part A and B) every time before using.

1. Preparation of the two components

Before mixing A and B components together, BLUESIL ADDITIVE PM A must be introduced into SILBIONE RT GEL 4725 PM A, and BLUESIL ADDITIVE PM B1, BLUESIL ADDITIVE PM B2, BLUESIL STOPPER BR1 must be introduced into SILBIONE RT GEL 4725 PM B.

SILBIONE RT GEL 4725 PM A&B does contain fillers which tend to rise to the surface, so it is necessary to stir both components to get homogeneous product prior to use. The homogenised components are stable for up to one hour without the need for remixing. After one hour it is strongly advised to remix the components before further use.

Alternatively, the two silicone parts can be kept in slowly stirred tanks. Using this method requires temperature control in order to avoid alterations of potlife and degradation of the product.

2. Mixing the two components

After introduction of the additives, the components A and B are mixed according to 1:1 ratio as indicated below.

The mixing can be carried out either by using a low-speed electric or pneumatic mixer to minimise the introduction of air and to avoid any temperature increase.

It is also possible to use a special mixing and dispensing machine for the two silicone components. Further information is available upon request.

3. Degassing

The mixture should be degassed preferably at 30 to 50 mbar to eliminate any entrapped air. If a dispensing machine is used, the two components are degassed separately prior to mixing.

The silicone mixture expands 3 to 4 times its initial volume and bubbles rise to the surface. Wait a few minutes to complete the degassing and then release the vacuum. The silicone is ready for pouring, either by gravity or under low pressure.

Note: Release the vacuum once or twice accelerates the degassing. It is recommended to use a container with a high diameter / height ratio.

4. Polymerisation

The system polymerises at 23°C. The curing may be slowed down at lower temperature or accelerated by heat.

Contact with certain materials can inhibit the crosslinking. See list below:

  • natural rubbers vulcanised with sulphur,

  • RTV 2 silicone elastomers catalysed with metal salts, e.g. tin-compounds,

  • PVC stabilised with tin salts and additives,

  • epoxy resins catalysed with amines,

In case of doubts, it is recommended to test the substrate by applying a small quantity of the mixed silicone on a restricted area.
