Instructions
For The
Surface SWYPE鈩?
Aliphatic Amines
1. Lightly spray the area or item (workbench, tool, control knob) with cleaning
solution.
2. Wait at least 30 seconds, then wipe with a Surface SWYPE餂? pad.
3. Allow 3 minutes for the color to develop. A fuchsia color indicates that
aliphatic amines may be present. This color reaction relies on detecting the
alkaline pH of aliphatic amines.
Aromatic Amines
1. Lightly spray the area or item (workbench, tool, control knob) with developing
solution.
2. Wait at least 30 seconds, then wipe with a Surface SWYPE餂? pad.
3. Allow 3 minutes for the color to develop. A red-orange color is specific for
isocyanates.
Aliphatic Isocyanates
1. Lightly spray the area or item (workbench, tool, control knob) with the
developing solution.
2. Wait at least 30 seconds, then wipe with a Surface SWYPE餂? pad.
3. Allow 3 minutes for the color to develop. A red-orange color is specific for
isocyanates.
Aromatic Isocyanates
1. Lightly spray the area or item (workbench, tool, control knob) with developing
solution.
2. Wait at least 30 seconds, then wipe with a Surface SWYPE餂? pad.
3. Allow 3 minutes for the color to develop. A red-orange color is specific for
isocyanates.
Hydrazine
1. Lightly spray the area or item (workbench, tool, control knob) with deionized
water.
2. Wait at least 30 seconds, then wipe with a Surface SWYPE餂? pad.
3. Allow 3 minutes for the color to develop. A color change from yellow to blue
indicates the presence of hydrazines.
Acids / Bases
1. Lightly spray the area or item (workbench, tool, control knob) with developer
solution.
2. Wait at least 30 seconds, then wipe with a Surface SWYPE餂? pad.
3. The acid detector will change from neutral (orange) color to fuchsia/magenta
at pH 3. For caustic exposures, the indicator will change to blue at pH 9.5.
