Tec7 MS Polymer Adhesive

Bond, Mount and Seal, Even Underwater

Tec7 MS Polymer Adhesive is an all-in-one solution, replacing seven different products with a single tube or suasage to get the job done right. It’s not to be confused with a standard silicone sealant, Tec7 is a solvent-free MS polymer-based adhesive that bonds, seals, and mounts, even under water. For over 25 years, Tec7 has remained the original all-rounder and the most trusted name for bonding, sealing, and fastening across countless industries.

Tec7 is also the leading MS Polymer Adhesive for PET Acoustic Panels, making it the preferred choice for installers and professionals working with acoustic materials. When performance matters, professionals and experienced tradespeople reach for Tec7, because it works the first time, every time. Whether in construction, sanitary applications, or general maintenance, Tec7 consistently delivers. It replaces mounting adhesive, wood and PU adhesives, silicone and sanitary sealants, acrylic adhesives, and butyl caulking—making it the number one choice for 80% of all sealing and bonding tasks.
