LOCTITE® SI 5248
Known as LOCTITE 5248
Features and Benefits
This versatile 1-part light-curing silicone material is used for the assembly, potting and coating of medical devices, especially those comprised of silicone or requiring high flexibility. Combined with a secondary moisture cure mechanism it allows for shadow curing.
LOCTITE® SI 5248 is a translucent, straw-colored, thixotropic light-curing acetoxy silicone sealant. It has deep light cure capability – both ultraviolet and visible – combined with a secondary moisture cure mechanism for shadow curing. It combines high strength with high flexibility on a variety of substrates: it is suited to plastics and highly suited to glass, ceramics and metals. It fluoresces under UV light – great for quality control – and has a tack-free time >30 secs and a fixturing time also >30 secs. ISO 10993 quality tested.
- Highly flexible sealant/adhesive
- Secondary moisture cure for shadow curing
- Extremely versatile: well suited to glass, ceramics and metals
- 1-part: no mixing required
- ISO-10993 biocompatible
