Features and Benefits
slide 1 of 1
Available sizes:
A 1-part, highly flexible, fluorescent instant adhesive for reliable assembly of flexible medical devices and other flexible components.
LOCTITE® 4902 FL offers significant performance enhancements compared to standard cyanoacrylates, including strength in flexing bond lines and resistance to leaks, with excellent sealing capability. Known performance advantages of cyanoacrylates are maintained, including speed, ease of use and strength. The fluorescing property supports automated sensing and vision systems for ease of detection of adhesive coverage and placement, resulting in production efficiency and quality assurance.
- High strength in flexing bond lines
- Excellent sealing capability to prevent fluid leakages
- ISO-10993 biocompatible
- Unique fluorescent adhesive for application and location verification

How to
Step by Step Guide
1. Preparation - Cleaning
It is recommended to use the correct LOCTITE® cleaner for the surface to be bonded (such as LOCTITE® SF 7070) to degrease and clean surfaces prior to applying the adhesive.
2. Preparation - Priming
To improve adhesion on difficult to bond plastic surfaces, apply LOCTITE® SF 770 to the bond area by brushing or dipping. Avoid applying excess primer. Allow the primer to dry.
3. Preparation - Activation
If cure speed is too slow, use activator LOCTITE® SF 7452 or LOCTITE® SF 7455 (see cure speed vs activator graph in TDS). Apply activator to one bond surface by spray, brush or dipping (not primed surfaces). Allow the activator to dry.
4. Application
Apply adhesive onto one side/part.
5. Assembly
Assemble parts immediately. The parts should be accurately located as the short fixture time leaves little opportunity for adjustment. Bond should be held or clamped until the adhesive has fixtured. Hint: if necessary, excess product can be cured by activator LOCTITE® SF 7452 or LOCTITE® SF 7455. Spray or drop activator onto excess product.
Equipment
For precise dispensing of small amounts of adhesive, the use of dispensing needles is recommended.
