Tec7 Adhesive

Bond, Mount and Seal, Even Underwater

Available in White, Grey & Black 310ml cartridges and 600ml sausages

TEC7 is an all-in-one, offering just one product instead of seven to get the job done.

Not to be confused with a silicone sealant, TEC7 is a solvent free MS polymer based product that bonds, seals and mounts...even under water! TEC7 is the original all-rounder. For more than 25 years now, TEC7 has been the best-known sealant for bonding, sealing and fastening.

When it really has to be good, professionals and experienced handymen reach for the TEC7 tube. And rightly so! TEC7 is the first choice for 80% of all applications. For all applications: in the construction and sanitary sectors and general maintenance. TEC7 replaces mounting, wood and PU adhesive, silicone sealant, sanitary silicone sealant, acrylate adhesive and butyl caulking.
