Description

The LOCTITE 4902 FL Fluorescent Cyanoacrylate Adhesive, Clear, 20 g Bottle (SKU: 2103947) is engineered for demanding applications such as medical device assembly and flexible component bonding. This one-component adhesive delivers exceptional flexibility in bond lines, excellent seal resistance to leaks, and fluorescent traceability under UV light for quality-inspection systems. It maintains the speed and strength associated with cyanoacrylate adhesives while enhancing performance in applications subject to flexing.


Key Features

• Highly Flexible Bond Line: Designed to retain strength and durability even when assemblies bend or flex.

• Fluorescent Under UV: Enables automated sensing or visual inspection to confirm adhesive coverage and placement.

• Low Viscosity, One-Component Cyanoacrylate: Easy to apply without mixing, ideal for production line efficiency.

• Leak-Resistant Sealing Capability: Suitable for assemblies requiring a fluid-tight bond in dynamic environments.

• ISO 10993 Compliant: Meets biocompatibility criteria for use in medical device assembly.


Applications

• Flexible Medical Device Assembly: Bonding plastics, rubbers, metals in assemblies that flex during use.

• Inspection-Driven Production: Ideal when adhesive placement must be verified under UV light by vision systems.

• Dynamic Bonding Situations: Suitable for substrates and assemblies subject to stress, vibration or motion.


Benefits

• Superior Performance in Flexing Assemblies: Maintains bond integrity where standard adhesives may fail.

• Enhanced Quality Assurance: Fluorescent visibility ensures full coverage and placement—reducing defects and rework.

• Simplified Application: Single-component formula reduces process steps and downtime.

• Broad Substrate Compatibility: Bonds plastics, rubbers and metals—supporting streamlined inventory.

• Production-Ready Speed: Fast fixture time supports efficient manufacturing flow.

FAQs

What type of adhesive is LOCTITE 4902 FL and what makes it special?

LOCTITE 4902 FL is a one-component cyanoacrylate adhesive designed for high-performance applications. It is highly flexible, ensuring durability under stress and flexing. It also fluoresces under UV light, enabling easy inspection for adhesive coverage and placement, especially useful in automated quality control systems.

What materials can LOCTITE 4902 FL bond?

LOCTITE 4902 FL is suitable for bonding a variety of substrates including plastics, rubbers, and metals. It is commonly used in flexible medical device assemblies and applications that involve dynamic bonding situations, such as stress, vibration, or motion, where a reliable bond is required.

What are the performance specifications of LOCTITE 4902 FL?

LOCTITE 4902 FL has a fixture time of approximately 20 seconds on steel, with a shear strength of about 12 N/mm² (1,745 psi) on grit-blasted mild steel. It is resistant to temperatures between –40°C to +80°C (–40°F to +180°F), making it suitable for a wide range of applications.

Why is the fluorescent feature beneficial in LOCTITE 4902 FL?

The fluorescent property of LOCTITE 4902 FL makes it easy to visually inspect the adhesive placement and coverage under UV light. This feature enhances quality control by allowing quick verification of adhesive application, reducing defects and rework in manufacturing environments.

What are the storage and handling recommendations for LOCTITE 4902 FL?

LOCTITE 4902 FL should be stored in a dry location at temperatures between 2–8°C (35–46°F). Once opened, the adhesive should be used promptly to avoid contamination. It should not be stored in pure oxygen environments or near strong oxidizers.
