NGC Test Report #RCB-1003.

The proportioning equipment shall be manufactured specifically for heating, mixing and spray application of polyurethane foam and be able to maintain 1:1 metering by volume with + 2% variance. All proportioners shall have adequate main heating capacity to deliver heated and pressurized materials up to 140º F. Heated hose shall be able to maintain pre-set temperatures for the full length of the hose. 2:1 ratio feeder pumps and ¾ inch supply hoses are recommended to transfer material from container to the proportioner.

Recommended equipment (contact PSI for more details):

  • Graco Reactor proportioners or equivalent set at 1:1 volume ratio
  • Graco GAP or Fusion air-purge spray gun with #2 mixing chamber
  • Graco T2 2:1 transfer pumps or equivalent

Keep containers tightly sealed and stored at 50° to 75°F. for maximum shelf life. Storage temperatures must not exceed 85°F. Do not store in direct sunlight. Open the container slowly to allow any pressure to be released before removing the bung. Keep drums tightly sealed when not in use to avoid contamination. Water, solvents or oil in the liquid components will degrade foam quality. Protect from heat, sparks and open flame. Do not cut or weld near this container. Do not smoke near container. Do not store near food or feed.

Staycell ONE STEP 255 has a shelf life of approximately three (3) months from the date of manufacture when stored in original, unopened containers between 50° to 75°F. Staycell 265 has a shelf life of approximately three (3) months from the date of manufacture when stored in original, unopened containers between 50° to 75°F. As with all industrial chemicals, these products should be stored in a covered, secure location and never in sunlight or direct sources of heat. Storage temperatures above the recommended range will shorten shelf life and may also result in elevated headspace pressure within containers.
