UV Curing Plastic Bonding Adhesive
3309 UV Curing Plastic Bonding Adhesive is an amber transparent UV adhesive with high viscosity and fast curing. It provides a quick surface dry (tack-free) finish and good adhesion to a wide range of plastics including PC, PS, ABS, PMMA, PVC and APET. It is recommended for small to medium area plastic-to-plastic bonding such as phone quicksand cases.

Operation and Curing Guide
- Surface preparation: clean the plastic surfaces to remove oil, dust and contaminants for maximum adhesion.
- Dispensing: apply the adhesive evenly to the bonding area.
- Assembly: position and join the parts, pressing to spread the adhesive and removing any excess before curing.
- UV curing: expose the adhesive to UV light at 500 mJ/cm² (UV) until fully cured.
- Inspection: verify a uniform bond with a clean, surface dry finish and no bubbles.
- Rework: gently separate bonded parts, clean the surfaces and re-apply the adhesive when repair is needed.
FAQ
Q1: What is the 3309 adhesive mainly used for?
3309 is a UV curing plastic bonding adhesive recommended for small to medium area plastic-to-plastic bonding such as phone quicksand cases, with good adhesion to PC, PS, ABS, PMMA, PVC and APET.
Q2: Which plastics does it bond?
It provides good adhesion to a wide range of plastics including PC, PS, ABS, PMMA, PVC and APET.
Q3: What does surface dry mean?
The adhesive cures quickly to a good surface dry (tack-free) finish, so bonded parts can be handled sooner after UV exposure.
Q4: Why is high viscosity useful?
The high viscosity gives good control for covering the bonding area without excessive flow or squeeze-out.
Q5: What bond strength does it provide?
3309 has a Shore D 65 hardness, a shear strength of 9.5 MPa on PC/PC and 7.2 MPa on PC/PVC.
Q6: What are the storage conditions and packaging?
Store at 8-28°C in the original sealed container. Shelf life is 12 months. Available in 1kg / 5kg packaging.
