Abstract: Adhesive beads comprise a core comprising a pressure sensitive adhesive material and an essentially discontinuous organic polymer disposed about the core. The beads are free-flowing at room temperature. Upon application of heat and/or pressure the core is activated and blends with the coating to provide a pressure sensitive adhesive.

Abstract: Curable epoxy resin compositions, preferably solvent-free, wherein a fluorene amine curative is partially melt dissolved and partially dispersed as a solid in at least one aromatic polyepoxide. The compositions provide prepregs which exhibit tack with surprisingly good shelf life properties. Cured composites comprising the prepregs are also provided. The cured composites exhibit little resin migration and glass transition temperatures that are comparable to those of cured neat resins.

Abstract translation: 可固化的环氧树脂组合物，优选无溶剂，其中芴胺固化剂部分熔融溶解并部分地以固体部分分散在至少一种芳族聚环氧化物中。 组合物提供展示粘性的预浸料，其具有惊人的良好的保质期特性。 还提供了包含预浸料的固化复合材料。 固化的复合材料显示出与固化的纯树脂相当的树脂迁移和玻璃化转变温度。
