DURABILITY: CHEMICAL AND THERMAL RESISTANCE + HYDROLYTIC STABILITY
CNSL curing agents, and diols and polyols exhibit excellent chemical resistance and thermal resistance due to the aromatic ring and the hydrophobic aliphatic chain in their backbones. In addition, they are designed to deliver high bond strength, which in combination with their chemical and thermal resistance, results in very good anti-aging properties under different strenuous conditions. Exposure to high and cycling temperatures, and immersion in water and solvents cause limited weakening (accelerated failures) of the bonds.
Different from other renewable polyols, CNSL-based diols can be used as binders or in NCO terminated prepolymers to provide excellent hydrolytic stability after exposure to water and acid and alkaline solutions. Their good compatibility with other diols such polyethers and polybutadiene allows formulators to design blends that meet different performance requirements.
