352 UV Adhesive UV LED Curing 250ml Low Shrinkage Deep Cure Insulation Grade for PCB Component Fixing

352 UV Adhesive for PCB Electronic Component Fixing

The 352 UV adhesive is a single component, UV curable engineering adhesive developed for fixing electronic components on printed circuit boards. It is widely used for bonding PCB components, inductors and capacitors where fast, accurate positioning is required on high speed assembly lines.

Key Features

• Reliable component fixing – high bond strength holds SMD parts, inductors and capacitors firmly in place during handling, wave soldering and transportation, reducing rework caused by component shift.
• Moisture proof and electrical insulation – the cured layer forms a dense, non conductive barrier that protects circuits against humidity, salt mist and contamination while maintaining stable insulation resistance.
• Excellent surface and deep cure – dual curing behaviour delivers a tack free surface after short UV exposure and full depth curing in shadowed areas under the component body, ensuring no uncured residue.
• Low shrinkage – low volumetric shrinkage minimises internal stress on delicate leads, ceramic capacitors and fine pitch components, improving long term reliability.
• UV LED compatible – optimised photoinitiator system responds quickly to 365 nm and 395 nm UV LED curing systems, supporting short cycle times and lower energy consumption.

Recommended Applications

• Fixing SMD capacitors, resistors and inductors before reflow
• Protection and insulation of PCB test points and solder joints
• Bonding of electronic modules, sensors and coil assemblies
• Potting and sealing of small electronic assemblies

Typical Technical Data

Processing Notes

Apply the adhesive with a dispenser or pin transfer, position the component within the open time, then expose to a UV LED curing system. For components with large shadow areas, a short secondary cure or extended UV exposure is recommended. Store in a cool, dark place away from direct sunlight.
