The present invention provides solvent-based compostable cold seal release lacquers for use in packaging structures. The lacquers of the invention comprise resins, such as polyamide resins, comprising greater than 90% biobased carbon, generally prepared from renewable sources, e.g., plants such as rice. The present invention also provides the use of the inventive compostable lacquers as cold seal release lacquers in cold seal packaging, along with eco-friendly packaging film, etc., and has the potential to make the cold seal packaging fully compostable.

Adhesives comprising a silyl-terminated polyether and a tackifying resin provide a considerably reduced tack at relatively slight increases in temperature, undergo purely adhesive failure at such increased temperatures, and have reversible properties (i.e., such properties are substantially retained upon cooling). Such adhesives may be used to reversibly bond a first substrate surface coated with the adhesive to a second substrate surface by adhering the substrate surfaces together at a first temperature; heating the adhesive to a second temperature at least about 20? C. above the first temperature and below the thermal degradation temperature; and separating the substrate surfaces from one another at the second temperature, wherein the adhesive comprises the cured product of a silyl-terminated polyether and a tackifier. Such adhesives may also be cleanly transferred from to a different substrate at such elevated temperatures. Such adhesives may be used for tapes suitable for easy removal at elevated temperatures.

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%.
