1. Mixing the two components
The components A, B and BLUESIL ADD 11013 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.
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 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 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.
The system polymerises at . 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.
In case of doubts, it is recommended to test the substrate by applying a small quantity of the mixed silicone on a restricted area.

SILBIONE RTV 4418 ADH B
SILBIONE RTV 4418 ADH A&B is a two component silicone elastomer that crosslinks at room temperature by polyaddition reaction. The polymerisation can be accelerated by heat.
The system can be used in combination with BLUESIL ADD 11013 to glue certain fabrics with silicones.
By addition of 0.2 wt.-% BLUESIL ADD 11013 the system sticks on vertical forms. The components are available as viscous liquids, which cure after mixing to a translucent, resistance and flexible material.
- Outstanding adhesion between fabrics and silicones
- Same elastic behaviour as the substrate silicones
- Textile enforced prosthetic liners
- Textile covered insoles
