Operation and Curing Guide

1. Surface preparation: clean the surfaces to remove oil, dust and contaminants for maximum adhesion.
2. Dispensing: apply the adhesive evenly to the bonding area.
3. Assembly: position and join the parts, pressing to spread the adhesive and removing any excess before curing.
4. UV curing: expose the adhesive to UV light at 50 mJ/cm² until fully cured.
5. Inspection: verify a uniform bond with no whitening or bubbles.
6. Rework: gently separate bonded parts, clean the surfaces and re-apply the adhesive when repair is needed.

FAQ

Q1: What is the 3327 adhesive mainly used for?
3327 is a UV curing PET bonding adhesive used for PET packaging, window lenses and APET folding boxes.

Q2: How fast does it cure?
3327 cures extremely fast and can position in as little as 1 second under UV light at 50 mJ/cm².

Q3: Does it bond PET materials well?
Yes. 3327 provides very strong adhesion to PET, APET and PETG.

Q4: Why is low viscosity important?
The low viscosity makes dispensing easy and allows the adhesive to flow for a thin, uniform bond line.

Q5: What strength does it provide?
3327 has a Shore D 52 hardness, a tensile strength above 14 MPa and a shear strength of 6 MPa.

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 and 5kg packaging.
