Abstract: Structured adhesive constructions are provided. The adhesive constructions comprise a layer of a first adhesive with a first property and a layer of a second adhesive with a second property. The layer of the first adhesive comprises a plurality of spaced apart stripes of adhesive, coated on or laminated to a facestock or release liner. The layer of the second adhesive comprises a plurality of spaced apart stripes of adhesive, coated on or laminated to the facestock or release liner and located between the plurality of stripes of the first adhesive. The use of two different adhesives enables manipulation of desired adhesive properties in a single adhesive construction. The resulting adhesive may have two or more different desired properties, such as adherence at both high and low temperatures, or initial repositionability followed by permanent adhesion, or other combinations of desired properties. A coating die and a method of coating structured adhesive constructions are also provided.

Abstract translation: 提供结构化粘合剂结构。 粘合剂结构包括具有第一特性的第一粘合剂层和具有第二特性的第二粘合剂层。 第一粘合剂的层包括多个间隔开的粘合剂条，涂覆在面层或剥离衬垫上或层压到面材或剥离衬垫上。 第二粘合剂层包括多个间隔开的粘合剂条，涂覆在面层或剥离衬垫上或层压在面材或剥离衬垫上并位于第一粘合剂的多个条之间。 使用两种不同的粘合剂可以在单一粘合剂结构中操作所需的粘合剂性质。 所得粘合剂可具有两种或更多种不同的期望性质，例如在高温和低温下的粘附性，或初始重新定位性，随后永久粘合，或所需性质的其它组合。 还提供了涂覆模具和涂覆结构化粘合剂结构的方法。
