Reactive polyurethane hot melt adhesive strong bond PUR1100

PUR hot melt adhesive is a moisture-reactive polyurethane adhesive with 100% solid content, formulated as an isocyanate (NCO) terminated polyurethane prepolymer. It cures by reacting with moisture in the air, resulting in an adhesive that offers an excellent balance of cohesive strength and flexibility, making it both tough and durable. With its high flexibility, PUR is suitable for diverse climates and has found extensive applications in packaging, textiles, woodworking, automotive, electronic assembly, and other industries.

Reactive polyurethane hot melt adhesives are widely used in the field of paper-plastic and paper-aluminum composites.
This hot melt adhesive can effectively bond paper to plastic film or aluminum foil to form a strong and durable composite material.
Its advantages include fast curing, high-strength bonding, good temperature resistance and chemical stability, making it very suitable for food packaging, medical device packaging and industrial applications where high-performance bonding is required.
This adhesive can not only improve the physical properties and durability of the composite product, but also provide good appearance and printability, thus meeting the requirements of different industries for material bonding strength and aesthetics.

  • Details

The application cases of PUR adhesive (polyurethane hot melt adhesive) are very wide. Here are some specific application areas and their detailed cases:

Packaging industry:

In the packaging and reinforcement of cartons, PUR adhesive provides excellent bonding strength and can withstand the impact and vibration during the transportation of heavy objects. In addition, its moisture-proof properties ensure that good bonding effects can be maintained even in high humidity environments. It is widely used in the packaging of goods such as food and household goods.

Appearance Viscous liquid

2.Recommended Technology

Open time ≥5min
Coating temperature 80-110℃
Melt temperature 80-110℃
Coating methods Spraying or Roller coating
Glue amount The general coating amount is 2.5-4 g/m2, for reference only.
Preprocessing The substrate needs to be clean, dry and free of grease. For low surface energy substrates, corona or flame treatment may be required.
Preparation before gluing Please prepare the glue melter, heating plate, feed pump and discharge gun, and set the appropriate temperature. Excessive heating will cause the adhesive to decompose. It is recommended to use it below 130 degrees. Users who use glue melt tanks must use nitrogen for protection. The humidity of nitrogen must be below 5ppm, otherwise it will accelerate the formation of skin. After opening the package, please use it up as soon as possible.
Curing conditions In order to achieve complete curing, the compounded product can be stored at a suitable temperature and humidity (e.g. 25°C and 50% RH, or above). Under suitable conditions, curing will be completed within 7 days. At lower temperature and humidity, it will take longer to achieve complete curing.

3.Storage and safety

  • In a dry and clean environment at 5-30℃, the shelf life of the original unopened product is ≤9 months. The opened but unused product should be used up as soon as possible.
  • Be careful! Empty containers of adhesive also contain hazardous materials. Please follow the instructions on the container label and do not use empty containers without professional cleaning.
  • If you need more safety information, please refer to our product safety data sheet.
