ZJ-POR550
Polyolefin hot melt adhesive

ZJ-POR550 is an amorphous polyolefin hot melt adhesive obtained by copolymerization of ethylene, propylene, or butadiene. It has low VOC, is environmentally friendly, and has good adhesion performance to low polarity substrates. At the same time, it has good acid, alkali, and weather resistance. It is used in the fields of paper folding, edge filling, and sealing.

Product features

It has excellent adhesion strength to plastic materials such as PE, PP, PET, and also has good adhesion to substrates such as metals (such as aluminum) and paper;

Good weather resistance;

Excellent heat resistance stability;

Environmentally friendly, extremely low VOC.

Operation and Safety
  • Construction:
  • surface treatment
  • The surface of the adhesive substrate should be kept clean, dry, oil-free, and dust-free.
  • More information will be provided by our technical personnel.
  • Coating operation
  • Spraying or spot coating through heating equipment
  • Recommended application temperature is between 160~200 ℃, and the adhesive amount should be determined based on the actual bonding interface
  • Adhesion during opening hours (approximately 60 seconds @ 20 ℃)
  • After applying the adhesive, the temperature should not exceed 130 ℃, as repeated heating may alter the performance of the hot melt adhesive.
  • In order to achieve optimal bonding performance, the temperature of the substrate to be bonded should preferably be between 15 and 30 ℃.
  • According to the expected process parameters of processing time, such as opening time and curing rate, it may depend on the type of raw material quality, weight, and thickness. Please contact
  • Technicians investigate together the best choice you need.
  • Health and safety instructions:
  • Ensure a ventilated environment;
  • Do not come into contact with skin and eyes;
  • Wear protective gloves and glasses.
  • *In order to eliminate potential problems on site, Zhijiang samples various materials used for adhesives and determines the optimal adhesive to be used in advance
  • Agent to develop the best surface preparation method to obtain the best adhesive performance. Please consult the technical personnel of Zhijiang for specific information. The above information is in our possession
  • The laboratory provides that due to the large number of materials available in the market and different usage methods, it is beyond our influence and control
  • We cannot take any responsibility for the results of your work.
