Plastic Bonding UV Adhesive Fast Surface Dry Tack Free for PC ABS PMMA Acrylic

Plastic Bonding UV Adhesive (3303) 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, ABS, PMMA and acrylic. It is recommended for medium-area plastic-to-plastic bonding in assembly and packaging applications.

Technical Specifications

Key Features

• Fast curing with a surface dry, tack free finish
• Good adhesion to PC, ABS, PMMA and acrylic
• Medium viscosity for controlled dispensing and flow
• 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 of PC, ABS, PMMA and acrylic parts
• Medium-area plastic assembly
• Acrylic and PC display panel bonding
• 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 this UV adhesive mainly used for?
It is a plastic bonding UV adhesive recommended for medium-area plastic-to-plastic bonding, with good adhesion to PC, ABS, PMMA and acrylic.

Q2: Which plastics does it bond?
It provides good adhesion to PC, ABS, PMMA and acrylic, as well as other common plastics.

Q3: What does surface dry mean?
The adhesive cures quickly to a 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?
It 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.
