Product Description

Silicon gel is a special silicone rubber, which is divided into A and B components, mixed in 1:1 ratio and then cured. Before solidification, it is a liquid, and after solidification, it becomes a sticky, soft and elastic object on the surface. It is widely used in circuit board sealing, filter slot sealing, smart water meter sealing, and internal component sealing of difficult to stick plastic shells

Casting Adhesive Sealant Elastomer Product  code:  0105440/0105441

JOMS 5708 A/B
Two components soft gel elastomer Used for semiconductor devices

Description :
JOMS  5708  A &  B  is a two component silicone elastomer that crosslinks at room temperature by polyaddition reaction.The pueolymerisation can be accelerated by heat ( max. 150ºC ).
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 mattress, headrest, skin sticker, electric parts, IGBT module, junction box, auto control, and inverter.
Advantages :
 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
 High tensile strength

Processing
1.   Mixing the two components
JOMS  5708 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)
Used for semiconductor devices
3 .    Polymerisation
The  system,  as  indicated  in  the  technical  data, polymerises  at  25ºC .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.
In case of doubts, it is  recommended to test the substrate by applying a small quantity of the mixed silicone on a restricted area.
Storage and Packaging
The  JOMS  5708 A &  B  must  be  used  within  12 months with respect to the manufacturing date.
In   order   to    preserve    best    properties    it    is recommended   to   follow   strictly   the   following guidelines:
 Store the original packing tightly sealed and at a temperature below 30ºC
 Use the product as soon as the packaging has been opened.
JOMS  5708 A &  B is delivered in 10kg/10kg containers.
If  needed  special  containers  are  available  on request.
