| XT-507B is a thixotropic paste version of XT-500B, the RTV-2 silicone for ultra-low temperature potting, encapsulating and sealing applications. In this formulation, the crosslinker has been added to the Base to enable curing via the addition of a tin catalyst. XT-507 is excellent for cast-in-place heat shielding, thermal insulation, low and high temperature bonding and the potting and encapsulation of electrical assemblies that will be exposed to very low temperatures and where the rubber must remain in place or adhere to a vertical surface. |
