Appeal No. 2003-1251
Application 09/226,128
cyanoacrylate-based adhesives. Both are shown according to the
tables presented at the top of page 4 of this reference to
include the use of water as a solvent.
The discussion at the bottom of page 7 of the principal
brief on appeal appears to admit that the Loctite 408 material is
a form of heat-curable adhesive since it is admitted that it is
cured by heating. The polymerization process admitted here at
this portion of the brief indicates a permanent chemical change
such as to fairly characterize the Loctite 408 material as a
thermosetting adhesive in accordance with the Condensed Chemical
Dictionary definition attached to the reply brief.
When the Loctite 408 technical data sheet associated with
the reply brief is reviewed, we reach a similar conclusion. As
argued at the bottom of page 3 of the reply brief, this data
sheet does indicate that the Loctite 408 material is cured by
surface moisture. The data sheet does not indicate that it is
not cured by heating. Under the topic TYPICAL CURING PERFORMANCE
at column 1 of page 1 of this technical data sheet, it is stated
that "the surface moisture initiates the hardening process." It
appears that the data sheet intends the use of the word hardening
here to indicate curing since the paragraph continues by
indicating in turn that "curing" continues for at least 24 hours.
