Chemical Resistance Test Methods
Chemical Resistance Test Method
1, 1, 1-Trichlorethane Solvent resistance was determined using cured (24 hrs RT + 2 hrs 160°F [71°C]) samples (1/2 in. x 4 in. x 1/8 in. thickness) immersed in the test solvent for 1 hour and 1 month. After the allowed period of time, the sample was removed and visually examined for surface attack as compared to the control.
