A decorative sheet according to one aspect of the present disclosure comprises a decorative plate and an adhesive layer disposed on a first side of the decorative plate. The decorative plate comprises (A) a decorative layer disposed on a second side from the first side, (B) a core layer made of a prepreg containing a fiber base material, and (C) a balancing layer including mixed paper containing an endothermic metal hydroxide as a base material.

Aspects of the present disclosure provide for composite structures including a bonding layer that adheres a substrate (e.g., including a polymeric composition such as rubber) to a material (e.g., including a polymer such as polyurethane). The adhesion of the substrate to the material through the bonding layer can include chemical bonds such as, but not limited to, siloxane linkages, silanol linkages, silyl linkages, or any combination thereof in the bonding layer.

The present application is drawn to infrared reflective ink formulations, infrared reflective dried coatings prepared from such inks, and IR-reflective substrates and adhesive tapes prepared from such inks and coatings. The inks are suitable for printing by gravure or flexo methods onto polymeric substrates such as PET, paper, or other substrate materials. The coatings are reflective in the near-infrared range. The coatings and tapes are well suited for use in manufacturing methods. The coatings and/or the tapes are ultrathin, on the order of a few micrometers, making them attractive for use in different industrial applications.

A waterproofing membrane system for waterproofing a concrete substrate is disclosed. The waterproofing membrane may comprise a first layer comprising a thermoplastic elastomeric waterproof material using advanced polymerization and squeeze technology. The second layer may comprise a carrier sheet that comprises a fabric. The third layer may comprise an adhesive to provide bonding of the first layer with a concrete substrate upon contact. In addition, the third layer may reduce migration of water and vapor traveling between the first layer and the concrete substrate. In some examples, the waterproofing membrane may also comprise a fourth layer to provide mechanical protection and ease of handling for the first layer, the second layer, and the third layer. In some examples, the first layer may comprise a thermoplastic polyolefin (TPO), the fabric may comprise polypropylene and/or polyethylene, the adhesive may comprise a C5 petroleum resin, and the fourth layer may be a protective coating comprising quartz sand (SiO2) having a reflectivity of 4.5%.
