COATING COMPOSITIONS FOR BUILDING MATERIALS AND COATED BUILDING MATERIAL SUBSTRATES
PROBLEM TO BE SOLVED: To provide coating compositions which can be used on porous substrates particularly porous nonwoven substrates, while providing desired water vapor permeance at a low relative humidity.SOLUTION: A coating composition to selectively retard water vapor as a function of humidity when cured into a barrier layer comprises: a. a hydrophobic component including a latex; and b. a hydrophilic component including a polyvinyl alcohol, polyvinylpyrrolidone, starch, cellulose, polyacrylate, polyacrylic acid, highly carboxylated latex, amine, inorganic hydrophilic filler, polyethylene oxide, vinyl ether, highly hydrolyzed polymer, polysaccharide or combination thereof. The water-vapor permeability according to ASTM E96 at 21°C after curing the composition applied onto kraft paper is about 1 perm or less at 25% average RH and about 15 perms or more at 95% average relative humidity.SELECTED DRAWING: Figure 2
【課題】低相対湿度で望ましい水蒸気パーミアンスを提供しつつ、多孔性基材、特に多孔性不織布基材で使用可能なコーティング組成物の提供。【解決手段】ａ．ラテックスを含む疎水性成分及び、ｂ．ポリビニルアルコール、ポリビニルピロリドン、デンプン、セルロース、ポリアクリル酸塩、ポリアクリル酸、高カルボキシル化ラテックス、アミン、無機親水性充填剤、ポリエチレンオキシド、ビニルエーテル、高加水分解ポリマー、多糖類、これらの組合せを含む親水性成分を含み、クラフト紙上に組成物をコーティングし、硬化後のＡＳＴＭ Ｅ９６に従った透湿度が、２１℃２５％平均ＲＨにおいて約１パーム以下、かつ９５％平均相対湿度において約１５パーム以上である、バリア層へと硬化した際に湿度に応じて水蒸気を選択的に凝結遅延するコーティング組成物。【選択図】図２
