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

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.
