BR 127 by Syensqo offers exceptional structural durability and environmental resistance, performing reliably across a wide temperature range from –67°F to 300°F (–55°C to 149°C). This aerospace epoxy primer enhances bond-line integrity by preventing hydrolysis of oxide layers, inhibiting corrosive undercutting, and improving hydrolytic stability at the adhesive–substrate interface. Its compatibility with nearly all 250° F film adhesives, along with its application flexibility — usable both within bonded areas and as a standalone protective coating — makes it ideal for critical aerospace structures.
