- Description
- Technical specification
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.

FAQ
This is a result of stress cracking. Leaving uncured liquid CA remaining on some plastic substrates (such as polycarbonate, acrylic, and polysulfone) in a stressed condition, may cause the formation of cracks in the plastic. Some remedies for avoiding/minimizing stress cracking are closing the bond joint quickly, using reinforced grades of plastic, anneal parts, or speed cure the adhesive with accelerator or light (for light cure products only).
All necessary H&S measures and PPE (personal protection equipment) requirements can be found on the product material safety data sheet, all of which are available via our website.
This is called blooming. This often occurs when there is an excessive amount of product being applied. To avoid blooming, use proper ventilation, less product, lower humidity, use a primer/accelerator, or a low bloom product.
Yes, instant adhesives should be stored in the refrigerator prior to opening, but DO NOT refrigerate them once they have already been opened. After opening, the product should be used within 30 days for best performance.
