UV Curing Plastic Bonding Adhesive Medium Viscosity Fast Cure Surface Dry for Multi Plastics

UV Curing Plastic Bonding Adhesive

3303 UV Curing Plastic Bonding Adhesive is a light yellow transparent UV adhesive with medium 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 medium-area plastic-to-plastic bonding in assembly and packaging applications.

Technical Specifications

Key Features

• Medium viscosity for controlled dispensing and flow
• Fast curing with a good surface dry (tack-free) finish
• Good adhesion to PC, PS, ABS, PMMA, PVC and APET
• Reliable bonding across multiple plastic substrates
• Recommended for medium-area plastic-to-plastic bonding
• High hardness (Shore D 58) for a durable bond
• Consistent performance for assembly and packaging

Applications

• Plastic-to-plastic bonding
• Medium-area plastic assembly
• Bonding of PC, PS, ABS, PMMA, PVC and APET parts
• Consumer electronics and appliance plastic housing
• Display and packaging plastic assembly

Operation and Curing Guide

1. Surface preparation: clean the plastic 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 700 mJ/cm² until fully cured.
5. Inspection: verify a uniform bond with a clean, surface dry finish and no bubbles.
6. Rework: gently separate bonded parts, clean the surfaces and re-apply the adhesive when repair is needed.

FAQ

Q1: What is the 3303 adhesive mainly used for?
3303 is a UV curing plastic bonding adhesive recommended for medium-area plastic-to-plastic bonding, 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 medium viscosity useful?
The medium viscosity gives good control for covering medium bonding areas without excessive flow or squeeze-out.

Q5: What bond strength does it provide?
3303 has a Shore D 58 hardness, a shear strength of 7.5 MPa on PC/PC and 6.5 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 packaging.
