Abstract:
Bio-renewable sources used during manufacturing of polyurethane (PU) adhesives
have been used extensively from last few decades and replaced petrochemical
based PU adhesive due to their lower environmental impact, easy
availability, low cost and biodegradability. Bio-renewable sources, such as
vegetable oils (like palm oil, castor oil, jatropha oil, soybean oil), lactic acid,
potato starch and other bio-renewable sources, constitute a rich source for the
synthesis of polyols which are being considered for the production of
“eco-friendly” PU adhesives. Various bio-renewable sources for synthesis of
bio-based PU adhesives and their potential applications are discussed in this
review. This paper will focus on the progress of research in bio-based materials
for adhesive application.
