How to use pur profile wrapping hot melt adhesives

1. Understand the boards to be bonded (MDF, solid wood, aluminum alloy, plastic, etc.) and the wrapping materials (PVC film, PET film, solid wood veneer, Leather, etc.), and ask the glue supplier to provide suitable PUR hot melt adhesive.
2. Open the temperature panel of the wrapping machine, set the temperature (130-150°C), and preheat the pur hot melt adhesive.
3. Set the glue application amount and wrapping speed of the machine, and start wrapping.
4. Place the finished product in a natural environment for 48 hours before proceeding to the next processing step.

Materials suitable for profile wrapping

( PVC film, PET film, PP film, Solid wood veneer, Paper, Leather, etc. )

Application notes

1. The PVC film needs to be back-coated, the MDF surface needs to be flat and clean, and the plastic steel, wood plastic and acrylic boards need to be activated.
2. The recommended ambient temperature is 15-30℃. If it is lower than 10℃, heating equipment needs to be added.
3. The glue cannot come into contact with air or water vapor before use.
4. The glue port needs to be sealed when production is stopped. If the machine is shut down for more than 1 week, it is recommended to clean the hose and glue port.

Pur profile wrapping hot melt adhesives FAQs

Q1. What are the advantages of PUR profile wrapping hot melt adhesive compared with EVA profile wrapping hot melt adhesive?

A1. PUR profile wrapping hot melt adhesive is a reactive polyurethane adhesive, which has stronger bonding strength, high temperature resistance, moisture resistance and solvent resistance than EVA hot melt adhesive. Therefore, the finished product is more suitable for transportation in high temperature and high humidity shipping containers, and is also more suitable for use in harsh environments such as outdoor and humid toilets.

Q2. Why can’t the wrapping materials be adhered after wrapping with pur hot melt adhesive?

A2. a. No pretreatment (such as heating, electric shock, application of affinity agent, etc.) was performed on the special wrapping material. b. Insufficient pressure from the pressing wheel. c. Too little glue was applied. d. The glue started to bond before reaching the required heating temperature.

Q3. Why is there “bubbling” on the surface of the board after wrapping with pur hot melt adhesive?

A3. a. The board has not been dusted or surface polished. b. The moisture content of the board is too high. c. The pressure of the pressure wheel is insufficient. d. The ambient temperature is too high.
