    Abstract: This invention relates to coated polyurethane foams and to a process for preparing coated polyurethane foams. More specifically, these coated polyurethane foams comprise (a) a polyurethane foam substrate, and (b) at least one bilayer of a coating composition on the foam substrate which comprises (1 ) a layer of a positively or negatively charged carbon allotrope, and (2) a layer of a positively or negatively charged polymer. When the carbon allotrope is positively charged, the other material is negatively charged, and vice versa. The final product (i.e. coated polyurethane foam) contains at least 1% by weight of the coating composition, based on 100% by weight of the coated polyurethane foam. The foams described herein have a surface resistivity of less than or equal to 1012 ohms per square.

    Abstract: The invention relates to a breathing adhesive sheet material comprising a sheet layer having apertures and an adhesive coating layer with apertures corresponding to at least part of the apertures of said sheet layer, provided on one side of said sheet layer having apertures, wherein said apertures in said adhesive coating layer constitute portions of a substantially continuous adhesive coating layer separated there from by remaining adhered to a protective sheet layer upon removal thereof. The invention also relates to a composite sheet material comprising such adhesive sheet material with a removable protective sheet layer provided to separate portions from the continuous adhesive layer upon separation thereof from the adhesive sheet material. The invention also relates to a method for manufacturing such an adhesive sheet material comprising the steps of applying a layer of uncured adhesive material to a sheet layer having apertures and a layer of protective sheet material, and submitting the sheet layer having apertures, the layer of protective sheet material and the layer of uncured adhesive material to a curing operation, thereby causing the layer of adhesive material to preferentially adhere to the sheet layer having apertures outside the apertures, and to adhere to the protective sheet layer at said apertures.

    Abstract translation: 本发明涉及一种呼吸粘合剂片材,其包括具有孔的片层和具有对应于所述片层的孔的至少一部分的孔的粘合剂涂层,其设置在所述片层的具有孔的一侧上,其中所述孔在 所述粘合剂涂层通过在除去保护片层后保持粘附到保护片层而构成从其分离的基本上连续的粘合剂涂层层的部分。 本发明还涉及一种复合片材,该复合片材包含这种粘合片材料和可除去的保护片层,所述保护片层用于从连续粘合剂层分离粘合片材料时从连续粘合剂层分离部分。 本发明还涉及一种用于制造这种粘合剂片材的方法,该方法包括以下步骤:将一层未固化的粘合剂材料施加到具有孔和一层保护性片材料的片层上,并使该片层具有孔, 保护片材料和未固化的粘合剂材料层进行固化操作,从而使粘合剂材料层优先粘合到在孔外部具有孔的片层上,并粘附到所述孔处的保护片层上。
