PowerFoam is a single component, moisture curing expanding polyurethane foam. The adhesive strength of PowerFoam allows it to be set on various types of building elements including concrete, brick, wood, metal, aluminum and steel. When installing the foam, consideration should be given to the 2-3 times expansion of the foam after it leaves the plastic tube. The surface of the foam initially dries within 1- 5 hours and becomes fully cured in 12-15 hours. The foam works best at room temperature. It is dispensed through a straw-like plastic tube that is packaged with the can. The structure of the hardened foam provides excellent insulation against heat and noise. The foam has a R-5 equivalent value when used in place of traditional installation methods. PowerFoam is used in applications where it is not necessary to control the size of the bead or the rate of flow. PowerFoam can be used in a wide variety of applications. Use it to fill, seal or insulate. It blocks drafts, stops leaks, saves energy, adheres to all types of construction material, deadens sound, acts as a buoyancy material once cured, controls radon, confines asbestos fibers, and can be used in HVAC applications. PowerFoam also seals and keeps out insects and rodents. After installation, it is recommended that a full 24 hours elapse prior to scraping, sanding staining or painting.
