Supex 2010 2K PU Adhesive
Supex 2K 2010 is a solvent free two component metal bonding glue based of polyurethane chemistry. Part A is terminated by hydroxyl group and part B is an isocyanate. A hard elastic product is formed through chemical reaction when mixed in a ratio of 5 : 1 (part A : part B).
USES
USES of Supex 2010 metal bonding glue
- Bonding of metal, fibre cement, wood and glass fibre reinforced polyester to expanded and extruded polystyrene foam, polyurethane foam and mineral wool in the manufacturing of sandwich elements and other constructions.
- Attaching ceramic tiles and mosaics onto wooden countertops or within kitchen areas to establish a waterproof base.
- Adhering ceramic tiles, stone materials, and various types of mosaics within showers and on pre- fabricated bathroom panels.
Why Use It for Metal Bonding?
- High Bond Strength: Capable of bonding metal surfaces such as steel, aluminum, copper, and stainless steel.
- Gap Filling Ability: Good for uneven or rough surfaces.
- Durability: Resistant to water, chemicals, UV light, and temperature fluctuations.
- Flexibility: Absorbs vibration and thermal expansion differences between bonded metals.

METHOD OF APPLICATION
Surface preparation: Prepare the substrates for bonding to ensure optimal adhesion and strength. Ensure to have a clean and dry surface. Certain substrates might require a physical or chemical pre-treatment. The type of pretreatment must be determined by tests.
Application: Adhesive components can be mixed manually, with stirring application or two- component mixing equipment. The product may be applied by spatula. The adhesive is only to be used Within a limited pot life. After this time the mixture gels up and is not suitable for use. Therefore only the amount that can be applied within the time of pot life should be mixed. The pot life depends on the quantity and temperature of the mixed batch. With larger quantities and an increase in temperature, the pot life decreases. Lower temperatures extend the pot life. Adhesive components should not come into contact with moisture during storage or application. Contact with moisture (water vapour) generates foaming of the adhesive and weakens the bondline. Therefore all packaging should be sealed properly and protected against humidity during storage.
Pressing: It is to be made sure that there should be no voids between substrate and the adhesive or adhesion defects might take place. Vacuum press is generally recommended for removal of air traps. The specific pressure is, however, dependent on the core material and must be determined by tests. The pressure must always be below the maximum compressive strength of the core. After starting the press process do not release the pressure until the press time has elapsed.
