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.
