CNSL-Derived Polyols: Enhancing Polyurethane Adhesive Performance with Renewable Materials

Overview

Cashew Nut Shell Liquid (CNSL) is a non-edible natural oil obtained as a by-product of the Anacardium Occidentale nut. In polyurethane applications, distilled CNSL (cardanol) can be successfully used as isocyanate blocking agent, viscosity reducer and raw material for the production of many compounds. Cardanol derivatives are suitable for both CASE applications and PU foams. We will present the performances of cardanol-based polyols in polyurethane adhesives, highlighting their benefits (e.g. hydrophobicity, chemical resistance, adhesion to various substrates) when compared to both fossil-based and natural-oil derived benchmarks, as well as their favorable sustainability profiles (LCA).
