Pictures of on-site application of  PUR hot melt adhesive for flat lamination

Fast curing speed and high peel strength

Excellent fluidity and wettability, good initial adhesion.

Good high and low temperature resistance and excellent aging resistance

A large number of boards can be bonded and can be fully cured in 72 hours.

How to use PUR flat lamination hot melt adhesive?

1. Confirm the board（density board, melamine board, multi-layer board, solid wood board, Chevron board, wood plastic board, aluminum board, glass magnesium board etc.） and material (PVC film、PET film、PP film、Acrylic、Leather、Paper etc.) to be bonded, and ask the hot melt adhesive supplier to provide the appropriate glue.
2. Set the machine’s melt temperature, the pressure of the glue roller, the amount of glue applied, etc.
3. Let the board pass through the conveyor belt into the dust removal device to remove dust on the surface of the board.
4. Apply the PUR hot melt adhesive evenly on the surface of the board, and then press the bonding material flatly on the board.
5. It is recommended to let the bonded board stand for more than 24 hours before proceeding to the next processing step.

Materials suitable for flat lamination

(PVC film、PET film、PP film、Acrylic、Leather、Paper 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 flat lamination hot melt adhesive FAQs

Q1. Why can’t the board and material be bonded together after using PUR flat lamination hot melt adhesive?

A1. a. The bonding was performed after the glue open time. b. The bonding pressure was insufficient. c. The board surface was overheated before bonding. d. The amount of glue applied was insufficient. e. The surface dyne value of the bonding material was lower than 38.

Q2. Why do wrinkles appear on the surface of the board after bonding with PUR flat lamination hot melt adhesive?

A2. a. Too much glue applied. b. The material to be bonded is too thin. c. The material to be bonded has too good tensile strength. d. The temperature of the sheet is too high. e. The material is overstretched before bonding.

Q3. Why does “bubbles” appear on the surface of the board after bonding with PUR flat lamination hot melt adhesive?

A3. a. The board is not flat and has impurities. b. The board temperature is too high. c. The initial adhesion of the glue is insufficient. d. The thickness of the bonding material is too thick. e. The amount of glue applied is insufficient. f. The bonding pressure is insufficient.
