H.B. Fuller

Applications & Uses

Application Instruction

Adhesive Application Process: Slot-die, Roller Coating, Spraying, Extrude Bead Strip.
Suitable hot melt equipment and adhesive application systems are required.
Please contact the local H.B. Fuller sales representative for more application recommendations and suitable product packaging that meet your actual production process needs.
Lamination Wrapping Process: Infrared Lamp Heat Activate Cold Press Mold, Hot Press Mold Lamination, Vacuum Pressure Holding Laminate.

Application Instructions

Do not open the package before complete the thawing
Thawing to temperature (160°C) before using.
Seal any remaining material and store immediately at temperature not up to 40°C.
We do not recommend thawing material more than three times

Curing Profile

To achieve complete curing, it is recommended that the laminated products be stored in an environment with suitable temperature and humidity of 25°C and 50% RH or above.
If the thickness of the adhesive film is 0.5 mm or less, curing will be completed within 7 days under suitable conditions.
At lower temperatures and humidity, it will take a longer time to reach complete curing.
The curing rate will be affected by various factors such as ambient temperature and humidity, adhesive film thickness, and substrate type.
Please contact the corresponding regional H.B. Fuller representative for detailed information about related products and processes.

Working Instruction

Substrate Surface Pretreatment: The bonding surfaces must be clean, dry and free of grease. Low surface energy substrates such as polyolefin materials must undergo plasma, flaming or other pretreatment.
Preparation: Prepare the glue melting machine, and set appropriate temp. for equipment such as heating plate, delivery pipes, pumps, gun heads, and glue rolling machines. Excessively high temperature for a long time will cause the glue to decompose and age. According to the structure of the equipment, set the temp. of heating plates, delivery pipes and pumps to within 160°C.
Glue Application: Adjust the parameters of the gluing equipment to achieve an ideal and reasonable amount of glue applied according to the surface condition of the substrate.
Lamination Wrapping Bonding: Adjust parameters such as the pressure, temp. and gap of the lamination mold to achieve the ideal lamination wrapping bonding effect. During lamination wrapping bonding, the temperature of the glue layer must reach above the required activation temperature.
Curing: The finished wrapped bonded parts need to be placed in the recommended temperature and humidity environment for curing.
Maintenance and Cleaning of Gluing Equipment: The application equipment must be cleaned regularly. It is recommended to use the cleaning agent Swift®clean 2018 to rinse the uncured glue remaining in closed glue melting equipment, gluing equipment and hoses, and use PUR-C60 to clean the uncured glue remaining on open equipment such as roller coating machines. For cured glue, it can only be removed by mechanical means.

Technical Details & Test Data

Curing Profile

The formation of the swift®lock 2077SP adhesive polymer is based on a moisture- curing mechanism; it depends on the temperature, humidity, applied glue thickness and permeability of substrates.
The ideal curing conditions should follow conditions:
Temperature:15~40°C
Relative humidity: 50~75%
Film thickness: <0.5mm
