ODAKE CT8886 UV Adhesive: ISO 10993-5 Certified Biocompatible UV Shadowless Glue for PVC and PC Bonding
In medical device manufacturing and food contact material processing, the selection of UV adhesive directly impacts product safety and reliability. When adhesives need to contact the human body or food, biocompatibility and food contact safety become non-negotiable requirements.
ODAKE CT8886 UV Adhesive is a professional-grade biocompatible UV shadowless glue developed for these applications. It is a medium viscosity, fast-curing, one-component UV curing adhesive that has passed ISO 10993-5 biocompatibility testing. It can be safely used in medical devices and food contact applications, and is specially recommended for bonding rigid or flexible PVC to polycarbonate (PC).
1. What Is Biocompatible UV Adhesive?
A biocompatible UV adhesive is a UV-curable adhesive that has been validated through biological evaluation (such as ISO 10993-5 cytotoxicity testing) to have no cytotoxic effects on human tissue. It is primarily used in medical devices, food contact materials, wearable devices, and other applications with strict human safety requirements.
CT8886 is ISO 10993-5 certified and can be safely used in:
-
Medical catheters, masks, and sensor assemblies
-
Food contact grade transparent plastic bonding
-
Precision assembly of medical devices
