Basics of...Foam Adhesives/Sealants/Void Fill

Foam Sealants: insulate and deliver an air-tight seal for building envelopes, providing cost savings. Cured product is completely inert and can easily be cut, sanded and shaped in 1 hour. Foam sealants also have a superior yield compared to caulk sealants. Wear eye protection and nitrile gloves; protect exposed skin; avoid breathing vapors; provide good ventilation.

Disposable Spray Foam Kits: come in user-friendly dispensing systems, which contain all materials needed to spray. Foam spray kits provide superior insulation performance and deliver an air- seal at merely 1�?�2�? depth. Kits use a non-flammable, non-ozone depleting propellant. Wear eye protection and nitrile gloves; protect exposed skin; use a respirator or an air-purifying organic vapor pre-filter device. All respirators or air purifying devices require medical evaluations and training under a certified respiratory program. Provide good ventilation.

Void Fill Foam Kits: can be sprayed into voids before curing. Longer cure times allow the product to fill any cracks and voids completely. Void fill foam can be used to add structural support, deaden sound, prevent vibration and provide buoyancy. Wear eye protection and nitrile gloves; protect exposed skin; use a respirator or an air-purifying organic vapor pre-filter device. All respirators or air purifying devices require medical evaluations and training under a certified respiratory program. Provide good ventilation.

Polyurethane Foam Adhesives: are moisture cured products that create an extremely strong bond between various materials. These foam adhesives will expand to fill all uneven surfaces and voids without the use of solvents that degrade polystyrene. They provide 10-30 times the yield of caulk-based adhesives, with up to 5 times the bond strength. Please see MSC′s safety section in Tab 12 for safety related products.
