摘要:
A method for rendering a substrate hydrophobic while maintaining its biodegradability includes treating the substrate with a reactive silane such that the reactive silane forms a resin in the interstitial spaces of the substrate. The method parameters are controlled such that the resulting hydrophobic cellulosic substrate is compostable.
摘要:
A method for rendering a substrate hydrophobic includes treating the substrate with an acyloxysilane. The treatment includes impregnating the substrate with an acyloxysilane and thereafter curing (hydrolyzing and condensing the acyloxysilane) to form a silicone resin. The method is particularly useful for rendering paper hydrophobic.
摘要:
A method for rendering a substrate hydrophobic while maintaining its biodegradability includes treating the substrate with a halosilane such that the halosilane forms a silicone resin in the interstitial spaces of the substrate. The method parameters can be controlled such that the resulting hydrophobic cellulosic substrate is compostable.
摘要:
Methods for rendering a cellulosic substrate hydrophobic include providing a plurality of halosilane compounds comprising at least a first halosilane compound and a second halosilane compound different from the first halosilane compound, wherein the plurality of halosilane compounds comprises a total halosilane concentration comprising 20 mole percent or less of monohalosilanes, 70 mole percent or less of monohalosilanes and dihalosilanes and at least 30 percent of trihalosilanes and tetrahalosilanes, and, treating the cellulosic substrate with the plurality of halosilane compounds, wherein the plurality of halosilane compounds are applied as one or more liquids.
摘要:
This invention pertains to neutralized silicone elastomer dispersions and methods for making neutralized silicone elastomer dispersions. This invention also pertains to compositions comprising the neutralized silicone elastomer and an acid reactive compound. The silicone elastomer dispersion are neutralized typically by blending the silicone elastomer dispersion with a base such as sodium bicarbonate or by adding a basic neutralizing agent to one or more of the raw materials used to make the silicone elastomer dispersion and removing the basic neutralizing agent by filtration or any other suitable means.
