  • Set-Up: Attach applicator gun to can (do not over-tighten), then shake well for 30 seconds.
  • Application: Dispense foam with can upside down, testing bead size on scrap metal first. Fill area about 25% full, leaving room for foam to expand. Note: To improve curing in arid regions, spray a light water mist into the cavity before applying foam.
  • Storage: Upright (50º-100ºF)
  • Foam Bonds To Skin Quickly: Wear gloves, eye protection and work clothes, use drop cloths.
  • For Best Results: Use in temperatures 60º-100º F (50% relative humidity).
  • Finish: Foam will be tack-free in about 10 minutes (50% R). Excess can be trimmed in about 30 minutes.
  • Can changeover: Once started, do not remove gun until can is empty; then purge gun and remove can. Clean gun thoroughly with acetone or polyurethane foam cleaner. Do not allow foam to harden in gun.

Caution: Contains Polymeric MDI, Polyurethane Resin & Propane/isobutene. Cure foam exposed to temperatures in excess of 240º F (116º C) may release hazardous decomposition products. Keep away from heat, sparks, flames and static electricity. Turn off sources of ignition (pilot light, etc.). Ventilate work area with moving, fresh air. Vapors heavier than air may cause flash fire or ignite explosively. Do not puncture, expose to heat or store at temperatures above 120º F 949º C). Do not leave in auto. Wear protective gloves, safety glasses, and work clothes.

First Aid Treatment – Skin Contact: DO NOT rinse with water (water helps curing). If foam is wet: remove immediately with acetone or polyurethane foam cleaner. After removal, wash with soap and water. If foam has dried: It is very difficult to remove. Do not try to remove with solvents. Cured foam wears of and it not harmful to health. Eye Contact: Flush with water for 15 minutes and get immediate medical attention. Inhalation: Over exposure to vapors may cause dizziness or headache – move to fresh air. Consult a physician if needed. Ingestion: Get immediate medical attention. Keep out of reach of children.
