A skin-to-core bond line mapping system and method is disclosed. Layered composite components formed by “sandwiching” multiple materials together require a continuous bond between those materials with voids below particular thresholds that can vary by application. The skin-to-core bond line mapping system can include a laminate, an adhesive, a separator film, a core, a breather, a layup tool, bagging material, sealant, and a vacuum port. By employing systems and processes that layer separator film over adhesive and applying a core proximate the adhesive, a bagging material can be disposed over the materials to facilitate vacuum compaction, thereby impressing core impressions on the adhesive to map the areas between the skin and core that have good contact. An iterative process is disclosed, in which additional adhesive can be used to build the bond line until contact is made (or engineering tolerance is reached).

A coating created entirely from plant-derived ingredients is disclosed. Illustrative embodiments of the coating may be particularly well suited for use on leather-like materials created from epoxidized natural rubber-based formulations. Illustrative embodiments of the coating created may be comprised of substantially the reaction product between epoxidized vegetable oil and a polyfunctional naturally occurring acid (such as citric acid). Illustrative embodiments this reaction product may be used to produce porosity-free castable resins and vulcanize rubber formulations based on epoxidized natural rubber. Materials made from disclosed materials may be advantageously used as leather substitutes.

The present disclosure relates to a pressure sensitive adhesive composition, comprising: a) a first (meth)acrylate copolymer comprising from 0.1 to 12 wt % of (meth)acrylic acid monomer units, based on the weight of the first (meth)acrylate copolymer; and b) a second (meth)acrylate copolymer comprising from 15 to 40 wt % of (meth)acrylic acid monomer units, based on the weight of the second (meth)acrylate copolymer. According to another aspect, the present disclosure is directed to a multilayer pressure sensitive adhesive assembly comprising a pressure sensitive adhesive composition as described above in the form of a first pressure sensitive adhesive polymeric layer, and which further comprises a second pressure sensitive adhesive layer adjacent to the first pressure sensitive adhesive polymeric layer. In another aspect, the present disclosure is directed to a method of manufacturing a pressure sensitive adhesive composition as described above and to uses thereof.
