Mapei Roof Foam G Mapei 750 cm3 polyurethane foam can (spray application)

MapePUR Roof Foam G is a one-component expanding foam contained in a pressurized spray can that is used in combination with a special MapePUR Gun Standard gun to feed the product. It is a one-component expanding foam made from a blend of polyurethane prepolymer, blowing agents and special additives and does not contain ozone-depleting CFCs. The extruded products expand on contact with moisture in the air and then rapidly harden to form a stable, closed-cell structure with excellent mechanical characteristics and high insulation and soundproofing properties.

The products are made from a blend of polyurethane pre-polymer, foaming agents and special additives and do not contain CFCs that can damage the ozone layer.

CARACTERISTICS

MapePUR Roof Foam G is characterized by its reduced rate of confined expansion to prevent them from lifting the bonded component in place, and are waterproof and resistant to temperatures from -40°C to +90°C, moisture and the effect of aging. The foam adheres well to all materials normally used in the construction industry, such as masonry, concrete, plaster, wood, metal, glass, Styrofoam, PVC and rigid polyurethane foam, and is also resistant to mold and mildew. Once hardened MapePUR Roof Foam G can be cut, sanded, ground, drilled, skimmed with cementitious products and painted. According to German DIN 4102 standards they are in flammability class B2. MapePUR Roof Foam G is certified as windproof.

AImportant caveats

A.

Neither version of the product, hand application and gun application, will adhere to polyethylene, silicone or Teflon. In addition, once hardened, the foam must be protected from direct UV exposure to prevent surface damage.

The amount of foam that expands depends on the size and shape of the cavity or space to be filled, the amount of moisture in the substrate, the temperature of the can and how well the various components of the can are mixed.
