Product Highlights: UV light cure adhesives are solvent-free resins employed for rapid, low temperature curing in fabrication of electronics components. They are especially important when precise alignment of parts and/or short production time is desired. Various types of adhesives be cured by UV light, but most of the commercial adhesives are acrylate- or epoxy-based.

ACW offers epoxy-based UV cure adhesives which provide a number of advantages. The adhesives have low reactivity including no interaction with LCD and OLED materials. The cured adhesives have high Tg, low outgas, low CTE, and low gas and moisture permeability. They are compatible with solder reflow temperatures and meet many reliability standards such as Telcordia and JDEC Level 3. Bonded parts survive temperature cycling with very small shifting.

ACW UV cure adhesives are employed in electronics and optoelectronics applications such as active alignment, fiber to V-groove bonding, waveguide assembly, chip edge sealing, and LCD and OLED device sealing. They are designed for UV-transparent substrates.

Thermal post cure at 80 to 100C for 30 to 60 minutes will promote full cure and improve adhesion of bonded parts

The recommended UV cure dose is at the adhesive. If the substrates absorb curing light, then the actual cure dose needs to be increased.
TGA DATA: Conditions: scan rate 10°C/min, in air

Safety & Health

Safety and Handling: The uncured adhesive can be cleaned from apparatus with isopropyl alcohol (IPA), methyl ethyl ketone (MEK), or commercial alcohol based cleaning solution. Avoid direct skin and eye contact. Use only in well ventilated areas. Use protective clothing, gloves and safety goggles.

Storage & Handling

Storage Conditions: 15 - 25
Shipment and Storage: Shipment: no restriction on shipment and no cold shipment is needed

Storage: After the adhesive is received in black syringes or amber HDPE bottles, room temperature storage (15-30°C) in the original container is required.
