APPLICATION
Stir product mechanically until a uniform liquid has been achieved. Use a low speed electrical stirrer (300–400 rpm) to avoid air entrapment. For roller application use short piled roller.
For airless application use tip sizes from 0.38 to 0.53 mm and angle from 40° to 60°.
CLEANING OF TOOLS
Clean all tools with water immediately after use. Hardened and/or cured material can only be removed mechanically.
