Recent advancements in Reactive Liquid Polymer Chemistry as New Tougheners for Epoxy Adhesives

Presented at China Adhesive 2015. Conclusions: CTB/CTBN combined adduct provides improved low temperature toughening while maintaining room temperature performance, does not phase separate, and results in less Tg decrease compared to traditional CTBN adduct. Glycidyl ester tougheners produce glycidyl ester with polybutadiene backbone directly and provide excellent room- and low-temperature toughening with less viscosity impact and less Tg decrease.
