According to Henkel, LOCTITE Si 5611 provides good gap filling and sealing capacity along with high durability and resistance to humidity as well as UV radiation. Typical applications include the production of solar and lighting systems, illuminated signage, switches and electronic connectors.

This two-part, low viscosity silicone is designed for both bonding and sealing. The basic resin is a white liquid and the hardener is black, creating a grey liquid when combined. A LOCTITE cartridge press gun with mixing nozzle ensures the efficiency of this process; standard and customised automatic dispensing equipment is also available. It is also self levelling and is particularly useful as a potting silicone to protect electronic components, increasing the quality and span of their service life. Service temperature is up to 200C.  

This addition to the LOCTITE silicone range has been formulated for applications that require a fast cure at room temperature. For example, a full strength bond on aluminium can be typically achieved in 12 minutes on a 0.13mm gap.
