Product Application Method Of Activator for Polyurethane/PU Sealant

  1.  Clean bonding surfaces with cotton swabs to remove dust, grease, and water. If rust is present, pre-clean with a wire brush.
  2.  Cut the nozzle to the desired size, screw it onto the sealant tube, then apply manually or using a compressed air gun.
  3.  To ensure optimal bonding performance and compatibility with substrates, conduct preliminary tests using actual substrates under corresponding environmental conditions.
  4.  For heavy components, use auxiliary tools (tape, positioning blocks, etc.) to secure the bonded parts after application.

Product Precautions Of Activator for Polyurethane/PU Sealant

  1.  Once opened, sealant must be used within the same day; otherwise, store strictly according to specifications.
  2.  Optimal working conditions: 15-35°C temperature and 55%-75% relative humidity.
  3.  When ambient temperature falls below 10°C or extrusion process requires it, we recommend baking the sealant in an oven below 50°C for 30 minutes.
