Web2.7 Sprayed Polyurethane. Polyurethane foam is sprayed over the surface of the prepared substrate. The polyurethane foam is coated with acrylic, urethane, or silicone rubber coatings. Roofing granules may be broadcast into the wet coating to improve weatherability. Uncoated foam “rusts” (forms a brown dusty layer). Often, the solid foams have lower nodal connectivity to that of the other cellular structures such as truss lattices and honeycombs, and therefore, their failure mechanism can be dominated by the bending of members. Ultimately, the low nodal connectivity and the resulting failure mechanism lead to their … See more Let us look at the types of foam or foam spray in detail.
