Improved durability and water repellency are provided to porous substrates by the use of a novel penetrating treatment composition comprising (A) C₁₀ to C₂₂ alkyl acrylate(s) or methacrylate(s) which are non-oxidizing and polymerizable to form homopolymers having a glass transition temperature of about 0°C or less and (B) autoxidative compound(s) which function as polymerization initiator-oxygen scavenger, wherein the weight ratio of (A) to (B) is about 50 to 95 to about 50 to 5.
通过使用新型渗透处理组合物,可提高多孔基材的耐久性和憎水性,该组合物包含 (A) C₁₀ 至 C₂₂ 烷基丙烯酸酯或甲基丙烯酸酯,它们是非氧化性的,可聚合形成均聚物,其玻璃化转变温度约为 0°C 或更低,以及 (B) 自氧化化合物,其作用是聚合引发剂-氧清除剂、其中(A)与(B)的重量比约为 50 比 95 至约 50 比 5。
