Dear Mr. Ringelstetter,

Rohm and Haas, as you are aware, supplies a wide range of adhesives to the packaging industry. requested that we share our isocyanate e xposure data as discussed in our telecom of 10 December.

We use OSHA Method 47 to assess exposure of affe cted workers to MDI (methylene diphenylene diisocyanate). Method 47 may be reviewed at http://www.osha.gov/dts/sltc/met hods/organic/org047/org047.html . In 2004, we assessed the exposure of our personnel to MDI. We chose Mor-F reeTM 403A as the test adhesive. This adhesive has a high level of MDI monomer (18.6% based on our data contained in our Certified Product Data Sheet). Three staffers were tested for potential exposure to MDI with the solventless laminator running, enclosure door open, and personnel in front of the machine. The three levels found were:

0.00055 ppm 0.00041 ppm 0.00067 ppm

In January of 2006, our industrial hygienist monitored personnel in the use of Mor-Free 403A and Coreactant C-411, this time at a customer’s site. Since this was a more formal investigation, an external analytical laboratory was employed to perform the analysis of samples in accordance with OSHA 47.

Two samples were collected from a point inside the lami nator above the adhesive pool that is typical in a solventless lamination machine. The samples showed airborne concentrations of 0.0072 and 0.0086 ppm MDI. Normal operations of solventless laminators in clude an exhaust system above the adhesive pool to collect, filter, and exhaust adhesive mists – to mini mize MDI exposure. To test the effectiveness of the enclosure, several area samp les were collected outside the enclosure around the exterior of the laminator. Samples collected outside the enclosure yielded results of <0.00014 ppm (below level of detection) and 0.00034 ppm. One of the operators was tested in duplicate during normal laminator operation and both results showed low exposure levels of <0.00018 ppm (below level of detection) and 0.00029 ppm. The

continuous nature of the tasks associated with th e operation of a solventless laminator and the close agreement of the consecutive measurements of MDI concentration are reasonable estimates of full-shift

exposure.The information presented herein is based upon our own research and general experience and is believed to be accurate and relia ble.

In addition, note that the airborne concentrations inside the enclosure

above the adhesive reservoir were extr emely low (0.0072 and 0.0086 ppm MDI).
