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, butyl caulking.
As a universal adhesive, Tec7 adheres to most substrates and does not attack synthetic materials.
To mirrors (vertical adhesive beads), natural stone (does not bleed through), metal, polyester, polystyrene foam, moist substrates, even under water.
To seal steel, welded steel and tack welded steel( also stainless steel type 316 and 316L), thus preventing rust.
Overpaintable with most common paints.
