BeGel 8715 A & B is a two component silicone elastomer that crosslinks at room temperature by polyaddition reaction.The polymerisation can be accelerated by heat ( max. 150℃ ).
The silicone components are delivered as two component low viscous liquids, which once mixed and cured,transforms into a transparent coloured,solid, elastic,self rebound and resistant material. Polymerisation occurs without formation of heat.
The cured gel is used in some medical applications with high strength, such as mattress, headrest, goggles, skin sticker.
• Fast mixing ( 1:1) and easy processing due to the low viscosity.
• Room curing at normal.
• Very fast curing kinetics at elevated temperature.
• Adhere and elastic surface
• good tensile strength

Mixing the two components
BeGel 8715 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.
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)
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.
