Wacker develops UV cured silicone for microelectronics

ERJ staff report (DS)

Munich, Germany -- Wacker Chimie has developed an improved range of UV-active silicone elastomers. Marketed under the tradename Semicosil UV, the new silicone grades cure at room temperature within a few minutes. The curing rate can be controlled by adjusting the UV dose as required. This enables manufacturers to encapsulate electronic components and PCBs faster and more economically. Wacker said the new grades are particularly suitable for key future markets - from automotive and power electronics through to sensor technology.

The novel UV-active silicone elastomers are easy-to-manage one- and two-component systems based on polyorganosiloxanes. The elastomers are characterised by a long shelf life, fast processing and the absence of any by-products on curing, said the manufacturer.
