SURFACE PROTECTION ARTICLES AND METHODS

Painting in commercial, residential, and retail environments requires extreme care to avoid paint being deposited where it is not required. Drop cloths are commonly used to protect a floor or furniture during the painting process. However, these are generally simply plastic sheets to provide a barrier to the liquid paint and nothing more. Accordingly, it would be advantageous to provide a drop sheet or tarp that supports a liquid material drying process such as by dehydration, coagulate, etc. or form solid materials thereby reducing the instances of subsequent paint transfer from the drop sheet or tarp directly or indirectly to other surfaces and / or objects. It would also be advantageous to drop sheet or tarp that provides a non-slip surface which prevents the drop sheet from sliding around and remains well in place without additional weights, tape, etc.

Gelatinous triblock copolymer elastomer particles in polyurethane flexible foams

Combinations of gelatinous elastomer and polyurethane foam may be made by introducing a plasticized triblock copolymer resin and/or a diblock copolymer resin at least partially cured into gel particles into a mixture of polyurethane foam forming components including a polyol and an isocyanate. The plasticized copolymer resin is polymerized to form a cured gelatinous elastomer or gel, which is then reduced in size, for instance to give an average particle size of 10 millimeters or less. Polymerizing the polyol and the isocyanate forms polyurethane foam. The polyurethane reaction is exothermic and can generate sufficient temperature to at least partially melt the styrene-portion of the triblock copolymer resin thereby extending the crosslinking and in some cases integrating the triblock copolymer within the polyurethane polymer matrix. The gel component has higher heat capacity than polyurethane foam and thus has good thermal conductivity and acts as a heat sink.
