Processing

  • Can be applied directly from the cartridge/bag using a suitable caulking gun (manual, air, battery) or using automatic dispensing equipment
  • The product can be spread using a spatula or brush on the surface
  • For large area bonds, the product can be applied with a notched trowel on the surface
  • The spray pattern can be applied with an air and application quantity controlling spray caulking gun. All structure types according to OEM (Original Equipment Manufacturer) can be set.
