Williams Honors College, Honors Research Projects
The purpose of this project was to determine and qualify suitable, environmentally friendly replacement(s) for the current Chemlok 233 adhesive cement used by UTC Aerospace. Chemlok 233 was discontinued by the manufacturer based on the availability of a hazardous solvent (Trichloroethylene – TCE). The Chemlok 233 Control and four Experimental alternates with similar properties were lab tested for adhesion strength in various UTC proprietary cement specifications. The specifications modeled Chemlok’s uses in the construction of pneumatic de-icers. Chemlok 2332 was selected for use in Cement A, and Chemlok 402 was chosen for use in Cement B based on their highest …
