English
Product Name
PP Polypropylene Bonding UV Adhesive Model: U401-x Brand: TADHE®
Introduction
This adhesive is a colorless transparent liquid (custom color available), formulated with modified acrylic UV resin. It cures under UV light at wavelength ≤395nm. It is specially designed for bonding, sealing and protection of PP polypropylene plastic parts. PP is known as difficult-to-bond plastic. This UV adhesive achieves strong adhesion on PP substrate. After curing, it features good toughness, excellent water resistance and weather resistance, low odor and eco-friendly. Suitable for manual dispensing and automatic dispensing production.
Specifications

Recommended UV Light Source
- 400W UV lamp, intensity:11mW/cm²
- 20W UV flashlight, wavelength ≤395nm
- Other qualified UV light sources that meet curing energy requirement
Operation Instruction
- Clean the bonding surface thoroughly, dispense adhesive slowly and avoid bubbles;
- Cure by UV light at distance 10–30 cm for about 15 seconds (adjust time according to UV lamp power);
- If glue layer is thick, increase UV light intensity or extend irradiation time;
⚠️ Note: Single curing layer thickness less than 1mm. Thick bonding layer should be dispensed & cured layer by layer.
- Seal leftover glue and store in cool & dark place.
Storage
Seal tightly, store at room temperature and away from light. Keep away from UV light to avoid premature curing.
Warning
- Avoid direct contact with skin and eyes. Wear gloves and goggles during operation;
- In case of skin contact, rinse thoroughly with clean water. If splashed into eyes, rinse continuously and seek medical help immediately;
- Keep good ventilation during use;
