Properties

  • Adheres excellently to many materials, such as stone, concrete, wood, gypsum, stucco, masonry, metal and various plastics, such as Styropor, hard PU foam, polyester and hard PVC.
  • Low-expansion quality, less filling capacity, less/light foaming during curing process.
  • High output, approx. 45 litres at free expansion.
  • Versatile: fills, seals, adheres, installs and insulates.
  • Very low emission: certified VOC emission class A+.
  • Excellent acoustic and insulating properties.
  • Fast-curing, fine-celled, easy to work with and cuttable polyurethane foam.
  • Lasting resistance to weather, water, moisture and ageing; does not rot.
  • Excellent resistance to hot and cold conditions, water and many chemicals.

Application conditions

  • Application temperature (ambient and surface) between +5°C and +40°C.
  • On compatible, stable, clean, uncontaminated and grease-free surfaces.
  • Use a suitable brush to remove any loose particles from the surface.
  • Degrease the surface properly using Seal-it® 510 CLEANER.
  • Give the canister approx. 20 good shakes before use.
  • Use a plant sprayer to lightly moisten the surface in advance.
  • After full curing, any excess Seal-it® 470 PU-FOAM GUN applied can be cut off with a knife and/or trowel.
  • Grease the gun adapter before use with Vaseline and/or PTFE spray, to prevent sticking.
  • After securing the canister in the gun, the spray speed and output volume are adjustable using the setscrew on the back of the gun, for optimal economic use.
  • When not using the system, tighten the setscrew on the back of the gun until it is closed so the gun can no longer be activated. Always leave the canister in the gun until it is completely empty.
  • Remove the empty canister by holding in the trigger while unscrewing it in order to expel any remaining gas. Next, reload the gun with a full canister, or clean the gun thoroughly using Seal-it® 450 PUR CLEANER.
  • If the gun is not working properly, put Seal-it® 450 PUR CLEANER on the gun, spray through several times, let set well for approx. 15 min., spray through again and then remove the Seal-it® 450 PUR CLEANER canister.
