Application Data

1. Soak a cotton pad with Topaz Indicator solution. 2. Wipe gently across the web on both the coated and non-coated areas of the sheet. The streak should be bluish and consistent in the applied area, showing a contrast with the non-coated area. 3. Color uniformity indicates the application uniformity level.


Ensure adequate ventilation. Keep away from open flames, hot surfaces and sources of ignition. Take precautionary measures against static discharges. To avoid ignition of vapors by static electricity discharge, all metal parts of the equipment must be grounded. Use only in an area containing flame proof equipment.
