FLASHBOND™ UV/LED-Cured Epoxy Adhesives

UV Cure Epoxies

FLASHBOND™ is Epoxyset’s line of cationic UV/LED-curable epoxy adhesives, formulated to combine the rapid curing advantages of light-activated systems with the strength and high glass transition temperatures typically associated with conventional epoxy chemistries. Unlike some light-curable materials, these adhesives are not affected by oxygen inhibition resulting in tack free surface. As single-component systems, FLASHBOND™ adhesives require no mixing, offer unlimited pot life prior to activation, and cure quickly when exposed to UV or LED light.

UV + Thermal Hybrid Options

Hybrid formulations offer UV tacking for rapid initial alignment, followed by a secondary thermal cure for final bond development. This approach allows components to be positioned and secured within seconds under UV exposure, then batch-processed through heat curing for completion. The result is a streamlined assembly process that supports precise placement while delivering reliable bond performance comparable to conventional thermally cured epoxies.

Frequently Asked Questions

 

1. What is a UV cure adhesive?
A UV cure adhesive is a material that hardens when exposed to light at the wavelengths specified for its formulation. It allows manufacturers to control when curing begins and can support fast assembly. Typical types are acrylated urethanes and epoxies.

2. How long does a UV adhesive take to cure?
Cure time depends on the adhesive, light wavelength and intensity, exposure time, bond thickness, and the amount of light that reaches the bond. Use the product’s recommended cure schedule and verify the bond under actual production conditions. In general, however it can be as quick as seconds (or <1 sec) up to minutes.

3. What should I consider when choosing a UV cure adhesive?
Start with the materials being bonded, required bond strength and flexibility, bond-line thickness, operating conditions, and whether light can reach the entire adhesive area. Then match the adhesive’s cure wavelength to the curing equipment and test the finished assembly under its intended conditions.

4. What are the advantages and disadvantages of UV cure adhesives?
Advantages of UV cure adhesives rely mostly on speed of cure which allows for higher throughput for manufacturing. Traditional adhesives can take hours or days to fully cure while most UV cure systems can cure in seconds. Most UV cure adhesives are one-component material which means no weighing or mixing required. Disadvantages include lack of variety when compared to traditional materials, inability to cure fully if adhesive cannot be exposed to light (i.e through opaque substrates), limitations in cure depth, and sometimes larger capital expense for UV lamps and curing systems.
