SILBIONE RT GEL 4021 QC B TRANSPARENT may be stored at a temperature between -20 °C/ -4 °F and 30 °C/ 86 °F for up to 12 Months from its date of manufacturingPlease consult the Safety Data Sheet of this product.

SILBIONE RT GEL 4021 QC B TRANSPARENT

SILBIONE RT GEL 4021 QC A&B and SILBIONE RT GEL 4021 QC TRANS A&B are two component silicone elastomers that crosslink at room temperature by polyaddition reaction. The polymerisation can be accelerated by heat.
The silicone materials are delivered as two low viscous liquid components, which once mixed and cured, transform into an elastic and resistant gel. Polymerisation occurs without formation of heat.

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

1. Mixing the two components

The components A and B are mixed by weight in the above indicated ratio. The mixing can be carried out either by hand or 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.

2. 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 to 3 to 4 times of its initial volume and bubbles rise to the surface. The bubbles progressively disappear and the mixture returns to its initial volume after 5 to 10 minutes. 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.

3. Polymerisation

The system polymerises at 23°C. The curing may be slowed down at lower temperature and contrary 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,

  • Certain organic solvents, e.g. ketones, alcohols, ether etc.

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