Low-bleed silicone based materials are used for critical applications where out-gassing of silicone could be an issue.  This includes electronics which use optical devices, devices with hard-drives, and certain critical automotive devices. Compared to traditional non-silicone gap fillers which are generally acrylic based, L37-3L is generally softer as it is silicone based, and has a higher working temperature than non-silicone based products.  This is one small advantage of this product and allows the design engineer a degree of flexibility which can drive down costs and manufacturing times. T-Global can provide comprehensive data on these products.  For example, where they show excellent stability and long service life time, more information and reports can be provided for these characteristics. Lastly, as well as having thermal properties, issues such as vibration can often be solved with the use of their materials.
