👷 📋 The Master Fitter's Verdict

"When you're sealing operating theatres, electronics cleanrooms, or commercial HVAC ducting, you cannot risk outgassing, corrosion, or seal degradation from heavy chemical disinfectants. S 67 is the only spec we trust for clinical and ventilation jobs. It grips bare metal perfectly without a primer, has virtually no odour, and stands up to aggressive hospital-grade cleaners day in and day out without breaking down."

Pro Tip: The S 67 non-corrosive alkoxy formula makes it ideal for sealing directly onto unprotected galvanized steel and aluminium ventilation ducts without causing any oxidation.
