The product exhibits low-temperature resistance capabilities down to -90℃ or below, making it suitable for special ultra-low-temperature elastomers and adhesives.
It is designed for materials requiring high elongation, ultra-low-temperature resistant adhesives and elastomers, as well as solid TJJ applications.
The primary differences lie in the hydroxyl value and viscosity: the HP type has a hydroxyl value of 11.8～15.2 mgKOH/g and viscosity ≤60 Pa.s (at 40℃), while the HT type features a hydroxyl value of 18.0～23.2 mgKOH/g and viscosity ≤80 Pa.s (at 40℃).
Both the HP type and HT type share the same number average molecular weight range of 7000～9000.
Both HP and HT types maintain an acid value limit of ≤0.10 mgKOH/g and a water mass fraction of ≤0.10%.
