Mapsil® AS Coating

White conductive silicone coating for launcher antistatic protection

MAPSIL® AS is a white conductive silicone coating developed for use on launchers Ariane 5 and Vega. The coating provides superior thermal protection with excellent thermo-optical properties, a very stable electrical conductivity as a semi conductive layer and a good adhesion on thermal protections (Silicone and cork based). This coating also provides a very high resistance to typical launch pad environment (Damp heat, temperature, UV, salt spray…) and on launch environment (To avoid any electrical surface discharge due to air friction).

Applications:

MAPSIL. AS is suitable to avoid any launcher heat on the launch pad and to avoid any electrical surface discharge due to air friction. This coating finds in particular an application on several types of substrates such as thermal protections:

• Prosial® LS
• Prosial® 2000
• Cork P50
• SV2A
• SV6G

as well as on :

• Aluminium 7075T0
• Glass

Due to its exposure to a variety of mechanical, thermal and electromagnetically environments, MAPSIL® AS was tested under short and long lasting ageing tests (according to Ariane 5 and VEGA specifications – see applicable documents):

• Short lasting ageing tests: Cold exposure, dry heat, electrical measurement vs temperature, vacuum test, salt spray test, thermal shock, streaming test, paint repairing.
• Long lasting ageing tests: Damp heat test, natural ageing in Guyana.

MAPSIL® AS is developed on specific technology to avoid any risk of inhibition and to limit the risk on human health and to reduce the environment impact.
