Permabond UV620 Medical Grade UV glue with High Optical Clarity, Very Clear, Transparent, thicker slow flow

Product Name

Permabond UV620 Medical Grade UV glue with High Optical Clarity, Very Clear, Transparent, thicker slow flow

Brief Description

Permabond UV620 is a single-part, fast-curing, UV-curable methacrylate ester adhesive. It is distinguished by its excellent optical clarity, resistance to yellowing, and medical device grade formulation. This adhesive forms high-strength bonds across a variety of substrates, including glass, metals, and plastics.

Popular Applications & Uses

- Bonding glass and crystal for a high-quality finish- Assembly of glass furniture- Creation of decorative ornaments and other glass objects- Medical device assembly, including catheters, syringes, diagnostic tools, and wearable sensors- Bonding of optical lenses, fiber optics, prisms, and highly-aligned plastic assemblies- General bonding of metal and plastic components in various manufacturing processes

Industries that Commonly Use It

- Medical Device/ Prosthetics- General Manufacturing- Furniture- LED/Electronics- Plastic Fabrication- Metal Fabrication

Special and Unique Features

- Medical Device Grade formula- Exceptional optical clarity and resistance to yellowing- Cures on demand when exposed to UV light- Achieves fast curing even with low-power UV lamps- Composed of 100% solids with no solvents- Provides high-strength bonds- Features a medium viscosity for controlled flow and effective gap-filling

Comparison Note

Permabond UV620 is a single-part, fast-curing UV adhesive that offers superior optical clarity and resistance to yellowing, making it particularly suitable for applications where aesthetics and transparency are critical, especially in medical devices and glass bonding. Its medium viscosity allows for controlled application and effective gap-filling, differentiating it from very low viscosity optical bonders or general-purpose adhesives.
