The strongest sealants we offer, these combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility.

Also known as Torr Seal, this sealant forms a rigid bond that seals leaks on vacuum systems or components.

Seal joints and gaps in concrete, brick, and stone.
