SC4003E

Silicone Resin

SC4003E is a two-part silicone potting and encapsulating resin designed for the protection of electronic devices.

It has excellent high temperature properties, suitable for use in applications where the operating temperature will

be up to 200°C

 Good flow characteristics to allow the potting of difficult and complex geometries

 Simple 1:1 mix ratio, for ease of processing

 Wide temperature range ideal for applications requiring high temperature resistance

 Soft resin, exhibits low stress on components

this without introducing air. Containers of Part A (Resin) and Part B (Hardener) should be kept sealed at all times when not in use to prevent the ingress of moisture. Bulk material must be thoroughly mixed before use. Incomplete mixing will result in erratic or partial curing. General Sedimentation of the resin has been minimised by careful attention to the formulation. However, any sediment which may have occurred over long periods of time must be dispersed before removing any material from the container.
