Foundation footing system for a load-bearing structure comprising a hole in the ground and a post in the hole extending above the hole. A gap present between the sides of the post and the sides of the hole contains a cured, hydrophobic, closed-cell, polyurethane foam to firmly hold the post in place and protect the post from moisture. Alternatively, a foundation footing system for a load-bearing structure comprising a hole in the ground filled with a cured, hydrophobic, closed-cell, polyurethane foam and a post place on and connected to the top of the foam.

Polyurethane foam in foundation footings for load-bearing structures

A cured coating or molded article prepared from a composition comprising an actinic-radiation curing polymer, wherein the composition is cured with actinic radiation at a temperature of at most 150&#xb0; C. to form the cured coating or molded article; wherein the cured coating or molded article has a thickness of at least about 0.5 mm and a hardness of about Shore A 90 to about Shore D 90.

Actinic radiation curable coating compositions

A gasket or other comprising a core and a flexible outer layer prepared by co-dispensing at a temperature of about 15&deg; C. to about 30&deg; C., a core composition and an outer layer composition, wherein the core composition is an elastomer or a foam and comprises at least two reactive components, wherein each component has a viscosity at 25&deg; C. of less than 10 cps. The core and outer layer compositions are applied in a non-solid state. The outer layer is preferably at least a two reactive-component elastomer or foam. A method for producing a gasket or other object comprising co-dispensing a core composition and an outer layer composition at a temperature of about 15&deg; C. to about 30&deg; C., wherein the core composition is an elastomer or a foam and comprises at least two reactive components, wherein the composition has a viscosity at 25&deg; C. of less than 10 cps.

Co-dispensed compositions for gaskets and other objects

Non-conductive, flexible, substrates having a conductive coating which are useful for EMI/RFI shielding applications. The conductive coating is compatible with the nonconductive substrate and provides continuous conductivity and complete EMI/RFI shielding.

Conductive coating on a non-conductive flexible substrate

An electrically conductive flexible polyurethane foam including a polyurethane and at least one conductive filler dispersed therein in an amount effective to provide EMI/RFI shielding, wherein the polyurethane comprises an isocyanate component to active hydrogen component in a ratio of at most about 0.20:1. Preferably, the foam has compression deflection value at 50% compression of at most about 25 psi, a foam density of at most 0.95 g/cm and/or noise shielding effectiveness at a frequency of about 20 to about 1000 MHz of at least about 10 dB.
