1. Mixing of the two components
Mix Part A and Part B components according to recommended weight ratios.
The materials can be processed differently according to the version:
BLUESIL ESA 6110 A&B
Hand mixing: The two components are thoroughly mixed using an electrical or pneumatic mixer, on a low speed setting so as to limit the inclusion of air in the mixture. A dispensing machine can also be used.
After mixing A and B parts, it is preferable to degas the product to eliminate the air bubbles that would be visible in the finished part and which would reduce the mechanical and dielectric properties.
Degassing is generally carried out with a vacuum of 30 to 50 mbar releasing the vacuum several times during the operation. A recipient with a high diameter/height ratio is better suited to quick degassing however the height must be sufficient to contain the swelling of the elastomer under vacuum conditions.
Automatic mixing: A dispensing machine can also be used (refer to procedure recommended for BLUESIL ESA 6110 QC A&B).
BLUESIL ESA 6110 QC A&B
The products should only be used by means of automatic dosing equipment with a meter/static mixer, as the pot life is too short to hand-mix and efficiently degas the material.
Automatic mixing: In order to avoid any air bubbles that may affect the mechanical and dielectric properties, it is recommended to degas separately A and B part, prior to pour it slowly and regularly into the tanks of the dosing machine. The A and B Parts should be dosed and mixed with a static mixer with a standard commercial equipment (A special care is recommended in pumping the product from the tanks to avoid any air entry before dosing and mixing).
2. After mixing
BLUESIL ESA 6110 A&B or BLUESIL ESA 6110 QC A&B are poured slowly and regularly. In the case of a high thickness potting operation, it must be made at the lowest point in the volume to be filled this avoids forming and including air bubbles in the volume. It should not be filled totally to allow expansion of the mixture at service temperatures.
Certain materials that the BLUESIL ESA 6110 A&B and BLUESIL ESA 6110 QC A&B may be in contact with when curing could inhibit the reaction. Especially troublesome materials are: sulphur-containing cured natural and synthetic rubber compounds (neoprene, latex, SBR), tin catalyzed silicone rubbers, amine catalyzed epoxies, PVC stabilized with tin salts and some polyurethane elastomers.
|BLUESIL ESA 6110 QC A may be stored at a temperature between -10 °C/ 14 °F and 30 °C/ 86 °F for up to 6 months from its date of manufacturing.||Please consult the Safety Data Sheet of this product.|
BLUESIL ESA 6110 QC A
BLUESIL ESA 6110 A&B is a pourable, two component silicone rubber that cures at room temperature by a polyaddition reaction, to a very soft and optical clear silicone gel.
BLUESIL ESA 6110 A&B is particularly recommended for high transparency applications.
A quick curing version, BLUESIL ESA 6110 QC A&B is also available.
