SKC 769-3003 PERMEA-TEC Sensor for Aliphatic Isocyanates
PERMEA-TEC Sensor for Aliphatic Isocyanates
Katse. Che. 769-3003
The PERMEA-TEC Sensor colorimetric screening method determines the effectiveness of chemical-protective gloves and clothing under actual use conditions. CLI’s microencapsulation detection indicator changes color, indicating permeation for many common aliphatic isocyanates. Results enable professionals to select the gloves/clothing best suited for protection, acceptance, and cost-effectiveness. Easy-to-use PERMEA-TEC sensors are adhered to a worker’s skin at points of greatest contact and abrasion before gloving or covering and are observed for color change at time intervals.

To determine a user-safe time period for the particular glove, double gloving is recommended.
- Affix PERMEA-TEC sensors to the thumb, middle finger, and palm on the outside of the glove currently being worn. Place the glove to be evaluated over the first glove.
- After one hour, remove the outside glove and the underlying PERMEA-TEC sensors.
- Evaluate the sensors for breakthrough. A positive indication of breakthrough results in a color change to red-orange.
- If no breakthrough is indicated, apply fresh PERMEA-TEC sensors and continue to wear the outside glove for another hour. Follow Steps 2 and 3 to determine if breakthrough has occurred.
- Repeat Steps 3 and 4 to determine a user-safe time period for gloves.
Other PERMEA-TEC sensors are available for:
- Aromatic Amines: MDA, aniline, o-toluidine, methylene-bis(2-chloroaniline) (MOCA)
- Aromatic Isocyanates: TDI, MDI
- Aliphatic Amines: N,N-dimethyl cyclohexylamine, triethanolamine, diet hanola mine, and triethylenediamine
- Acid/Base: HCI, HF, HSO, and NH,
- Phenols Solvents: Bisphenol A
