Fast cure potting silicone

Written by: Tom Austin-Morgan | Published:

LOCTITE has released LOCTITE Si 5611, an alkoxy silicone that is claimed to bring gap filling and sealing capacity, durability and resistance to humidity and UV radiation to electronic component assembly. Typical applications are in 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.A cartridge press gun with mixing nozzle is said to ensure the efficiency of this process; standard and customised automatic dispensing equipment is also available.

LOCTITE Si 5611 is also self-levelling and non-corrosive, making it suitable as a potting silicone to protect electronic components, increasing the quality and span of their service life.Service temperature is up to 200°C.

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.
