Darbond® 2598G RTV Silicone Sealant  (Instant Sealing)

Darbond 2598G is one component, de-oxime, room temperature vulcanizing silicone sealant. It has good properties of non-sagging, instant sealing, high elongation, low odor, no corrosion. Typically suitable for online and low pressure air impermeability test before cured, suitable for dispensing by pneumatic gun.


Typical Advantages & Application

  • Mainly used for flange sealing, 

  • good oil resistance and large joint movement resistance. Such as pressing metal cover (for example gear cover, oil sump tank etc.).
