Tec-Bond^® 235 and Tec-Bond 251 from Tectorius are established pre-applied fastener adhesives and threadlockers. They provide manufacturers with a seamless, dependable drop-in solution to continue production without retooling or requalifying existing fastener lines.

Both formulations feature microencapsulated adhesive technology that activates during installation to securely lock and seal assemblies. Tec-Bond 235 provides locking performance for general industrial use up to 150 °C, while Tec-Bond 251 delivers enhanced thermal resistance for demanding environments. Each order includes the Tec-Bond Booster, which can increase torque strength by 100–200% when properly applied.

The adhesives include the following key features:

• Direct replacement for 3M™ 2353/2510, enabling seamless transition and continued performance
• Durability in harsh environments, providing resistance to oil, water, antifreeze, and gasoline
• Multiple viscosities and colors, optimizing for coating systems and inspection needs

Providing water-based and solvent-free alternatives, Tec-Bond 240-IN and 261-IN deliver comparable performance with reduced environmental impact.

“Our goal was to provide an unambiguous replacement for the discontinued 3M 2353 and 2510 so customers can sustain performance without process changes,” said Mark Thurber, CEO of Tectorius. “Tec-Bond 235 and 251 deliver the reliability manufacturers expect in demanding assembly environments.”
