Mixing Ratio (By Volume):  100A to 100B

Combine Part A and Part B in the correct ratio and mix thoroughly until the color and consistency are uniform. Mixing the adhesive just prior to use is recommended. Heat buildup during or after mixing is normal. Do not mix quantities more than a pound as dangerous heat buildup can occur causing uncontrolled decomposition of the mixed adhesive. Mixing smaller quantities will minimize the heat buildup.
