Notes on the Source of the Red/Gray Chips
At the time of this progress report, the identity of the product from which the red/gray chips were generated has not been determined. The composition of the red/gray chips found in this study (epoxy resin with iron oxide and kaolin pigments) does not match the formula for the primer paint used on iron column members in the World Trade Center towers (Table 1).16 Although both the red/gray chips and the primer paint contain iron oxide pigment particles, the primer is an alkyd-based resin with zinc yellow (zinc chromate) and diatomaceous silica along with some other proprietary (Tnemec ) pigments. No diatoms were found during the analysis of the red/gray chips. Some
small EDS peaks of zinc and chromium were detected in some samples but the amount detected was inconsistent with the 20% level of zinc chromate in the primer formula.
Material Safety Data Sheets (MSDS) contain some information about product materials. According to the MSDS currently listed on the Tnemec website,17 55 out of the 177 different Tnemec coating products contain one or two of the three major components in the red layer: epoxy resin, iron oxide and/or kaolin (aluminum silicate) pigments. However, none of the 177 different coatings are a match for the red layer coating found in this study.
Excuse my ignorance, but what good are unidentified chips? What does it prove?" Please enlighten me, so I can understand the significance of this study. Thank you.

Can you please explain how you get into the shafts and plant these bombs? Obtaining access into the hoistways in a building like the WTC - covertly wouldn't be possible. ACE Elevator had technicians on property 24 hours a day. Eighty Mechanics were on duty on 9/11. You need to be a licensed elevator technician to be allowed access into these areas. IF you know anything about the unions in NYC, you too would realize your plan is bunk.
There were people that worked in the building that reported that they saw ceiling dust on tables in the morning in the week or so leading up to 9/11. Drop ceilings are good access points.
Really? Drop ceilings are a good access point to elevator hoistways? You are obviously not familiar with design and construction of elevators.
