Dymax Ultra Light-Weld 3069 Flexible Laminating And Bonding Material 30Ml Syringe (Pack Of 10)
Dymax Ultra Light-Weld 3069 Flexible Laminating And Bonding Material 30Ml Syringe (Pack Of 10)
Dymax Ultra Light-Weld® 3069 is a UV-cure adhesive designed for rapid bonding and laminating of both flexible and rigid substrates, including PVC, polycarbonate, polyurethane, PET, PETG, and ABS. Bond strength on polycarbonate and PVC typically exceeds the strength of the substrate itself. The cured adhesive remains flexible, making it well-suited for applications involving flexible lamination, plastic housing assembly, appliance assembly, and speaker assembly where rigid bonds would crack or delaminate under stress. Lead time is 1–2 weeks. Sold in packs of 10 x 30mL syringes.
Sold in packs of 10 syringes (30mL each).

Curing and Dispensing Guidance
The PDS reports fixture times of 1 second with a 2000-EC at 50 mW/cm², 1 second with a 5000-EC at 200 mW/cm², and 0.4 second with a BlueWave 200 at 10 W/cm². Those results are based on the stated test conditions and light transmission; they are not universal full-cure schedules. Dymax says actual cure time is typically three to five times fixture time, but full cure must be established empirically for the actual assembly by measuring cured properties.
Keep surfaces free of grease, mold release and other contaminants. Minimize exposure to ambient and artificial light before curing. Dispensing needles and fluid lines must be 100% light-blocking, not merely UV-blocking. Oxygen can inhibit surface cure; air-exposed surfaces may need high-intensity UV or an inert-gas process. Let parts cool after cure before testing or loading. Follow the PDS and SDS for processing and handling.
Frequently Asked Questions
What substrates is Ultra Light-Weld 3069 designed to bond?
3069 is formulated for bonding and laminating PVC, polycarbonate, polyurethane, PET, PETG and ABS. Dymax reports that strength on polycarbonate and PVC usually exceeds substrate strength, but the actual result depends on preparation, cure and the assembly. Test the intended materials rather than assuming universal compatibility.
Why is a flexible adhesive useful for lamination?
Dymax positions 3069 for flexible lamination and plastic assembly. Its typical elongation at break is 175%. Flexibility can be useful where bonded components move; validate durability under the application's actual loads and environment.
How is Ultra Light-Weld 3069 cured?
It cures with UV/Visible light. Lamp output, distance, bond gap, required cure depth and substrate transmission affect the process. The PDS fixture examples do not establish a universal full-cure time.
What is the difference between the 30mL and 10mL syringe options?
Both contain Ultra Light-Weld 3069. The 30mL syringe can suit higher-volume runs or larger deposits, while the 10mL option can suit smaller jobs and development work. This listing is specifically a pack of ten 30mL syringes.
What is the shelf life?
The PDS lists 18 months from manufacture at 10–32°C in the original unopened container. This does not mean every shipment has 18 months remaining. Keep material covered in a cool, dark place and protected from light.
Does Ultra Light-Weld 3069 contain solvents?
The PDS specifies no nonreactive solvents. Consult the SDS for safe handling; this statement does not eliminate the need for exposure controls or protective equipment.
Can I use ordinary transparent dispensing tubing?
No. Dymax specifies 100% light-blocking dispensing components, including needles and fluid lines, because both UV and visible light can initiate curing.
Is the 68°C glass-transition temperature the service limit?
No. Glass-transition temperature is a material property, not a validated operating-temperature range. Confirm service conditions with Dymax and test the bonded assembly.
