Shifting Adhesive Supply Chains: Hydrocarbon and Rosin Ester Tackifier Outlook
Global tackifier supply chains continue to shift as tariffs redirect trade flows and geopolitics disrupt sourcing and pricing. This presentation examines the global supply and demand fundamentals for hydrocarbon resin and rosin ester tackifiers used in adhesive applications, and explores how trade policy and geopolitical uncertainty are reshaping regional and global markets.
Combining Leonardo Siqueira’s expertise in pine based tackifiers with Steve Williams’ deep experience in C5 chemistry and hydrocarbon resin value chains, this presentation delivers a cross feedstock perspective on evolving global tackifier markets.
Drawing on insights regularly shared at leading industry forums, including the Adhesive and Sealant Council (ASC) Annual Convention, the FEICA European Adhesive and Sealant Conference, and the Pine Chemicals Association (PCA) International Conference, the session highlights key market trends, risks, and opportunities across both hydrocarbon resins and pine chemical based tackifiers.
