WHY THIS PAGE EXISTS
Topsil Silicone Gel TP-012 is part of our silicone solutions for potting and encapsulation applications. It is a pourable, addition-curing RTV-2 silicone gel developed for HEPA filter sealing and related air filtration applications. It cures at room temperature into a soft, tacky gel that can provide reliable sealing, environmental protection, and long-term flexibility.
Compared with rigid sealing materials, silicone gel can offer softer contact, better cushioning and more adaptable sealing performance in selected filter systems. It is suitable for applications where a soft gel seal is preferred over traditional gasket-style sealing.
The cured gel can reform after contact, helping maintain sealing performance in HEPA filter systems where seal integrity matters.
Suitable for applications where a softer seal is needed instead of a rigid sealing material.
Helps reduce bypass leakage and supports more stable sealing performance in demanding environments.
Designed for filtration applications that require sealing consistency and long-term material stability.
