Table 1: Tensile lap-shear strength at 23 °C / 50 % r.h. CURE MECHANISM Sikaflex®-268 PowerCure cures by reaction with moisture provided by the accelerator paste and largely independent from atmospheric moisture. For typical strength build up data see table below. CHEMICAL RESISTANCE Sikaflex®-268 PowerCure is generally resistant to fresh water, seawater, diluted acids and diluted caustic solutions; temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils; not resistant to organic acids, glycolic alcohol, concentrated mineral acids and caustic solutions or solvents.
