BeGel 8706 A/B Two components soft silicone gel

1. Components

2. Mixed components

3 . Cured compound 

Test at 25℃ after curing 7days at RT

Used for junction box, cable, connector whice need good warterproof.

Processing

1. Mixing the two components

BeGel 8706 A & B are mixed by weight in a fixed ratio given above.

The two components may be thoroughly mixed either by hand or using a low-speed electric or pneumatic mixer to minimise the introduction of air and to avoid any temperature increase.

Note: It is also possible to use a special mixing and dispensing machine for the two silicone

components.

Further information is available upon request.

2 .  Handling

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 2 to 3 minutes. Wait a few minutes to complete the degassing and then flash the vacuum. The silicone is ready for pouring, either by gravity or under low pressure.

Note: Flashing the vacuum once or twice accelerates the degassing. It is recommended to use a container with a high diameter/height ratio(3 to 4 times of the initial volume)

3 .  Polymerisation

The system, as indicated in the technical data, polymerises at 25℃ .The curing may be slowed down at lower temperature and contrary accelerated by applying heat.

Note: in general contact with certain materials can inhibit the crosslinking of RTV.

See list below:

• Natural rubbers vulcanised with sulphur
• RTV elastomers catalysed with metal salts,e.g. tin compounds
• PVC stabilised with tin salts and additives
• Epoxy catalysed with amines
• Certain organic solvents, e.g.Ketones, alcohols, ether  etc.
