Guardrail fasteners are critical components of a life-saving safety system. They are engineered to endure the highest level of catastrophic impact force imaginable, absorbing and transferring kinetic energy that can exceed hundreds of tons. These bolts are constantly under attack from relentless traffic vibration, extreme temperature cycling, and continuous corrosive environmental exposure. Fastener failure renders the guardrail system structurally compromised, leading to massive injury, fatality, and liability during a crash event.

For the engineering and infrastructure professional, securing these bolts is the ultimate act of public safety and structural assurance.

This is the non-negotiable territory of the INCURE Re-Lok™ Red Series—featuring the B72 Heavy Duty and B77 Extreme Duty Threadlocking Adhesives. They are engineered to create a unified, impact-resistant structure that maintains integrity at the moment of collision.

The Problem: Maximum Force Meets Environmental Decay

Are your safety barrier assemblies secured against these life-critical threats?

• Impact Shear Failure: The sudden, massive, multi-directional force of a vehicular impact will exploit any weakness or micro-movement in the joint.
• Corrosion Degradation: Perpetual exposure to road salt, water, and pollution accelerates rust and thread wear, systematically reducing the bolt’s load-bearing capacity.
• Vibrational Loosening: Constant traffic vibration works to strip the clamp load, enabling the guardrail to rattle loose before an impact even occurs.

Only a permanent, high-strength anaerobic lock can eliminate internal micro-movement and guarantee structural integrity against catastrophic dynamic forces.

The Position: Unyielding Structural Bond for Extreme Safety Barriers

The INCURE Re-Lok™ Red Series is the defined solution for permanent, high-strength applications where structural failure is unthinkable. By curing into a durable thermoset plastic, the threadlocker completely fills all microscopic gaps, transforming the rail-to-post joint into a single, unified component that withstands the most severe impact forces.

Here is the strategic defense the Re-Lok™ Red Series offers for guardrail fasteners:

1. INCURE Re-Lok™ B72 Red Threadlocking Adhesive – Heavy Duty

The High-Temperature and Anti-Fatigue Lock.

Guardrails endure extreme thermal cycling. The B72 (Heavy Duty) is essential for its ability to maintain its permanent, high-strength lock under extreme operating temperatures up to 230∘C. This guarantees the critical clamp load is maintained despite continuous thermal expansion and contraction.

2. INCURE Re-Lok™ B77 Red Threadlocking Adhesive – Extreme Duty

The Environmental and High-Shear Fortress.

The B77 (Extreme Duty) is engineered for maximum overall resistance to dynamic shear and chemical degradation. Its high viscosity formulation ensures superior gap filling for maximum resistance against impact forces, while its excellent chemical resistance creates an impenetrable seal against water, salt, and corrosion, preserving the thread’s long-term strength and crash-worthiness.

The Strategic Payoff

By investing in the targeted, high-performance security of the INCURE Re-Lok™ Red Series, you are making a non-negotiable commitment to public safety and infrastructure integrity. You are guaranteeing the permanent security of the life-saving barrier, ensuring it performs exactly as designed at the moment of impact.
