Appeal No. 2003-1251
Application 09/226,128
Although the remaining portions of the two pages of this
technical data sheet are silent as to the relationship of
temperature and curing, it appears that room temperature is all
that is necessary for the curing process to be effected in 24
hours. It is noted as well that the cured material has
different, distinct properties than the uncured material.
Of particular note is the statement from the definition
of thermosetting materials taken from the Condensed Chemical
Dictionary attached to the end of the reply brief. It is
indicated that alkyds are usually considered to be thermosetting
in nature. Consistent with this, the uncured material properties
of the Loctite 408 data sheet indicates that the chemical type of
this material is alkoxy-ethyl cyanoacrylate as noted at the top
of column 1 of page 1 of this data sheet. It appears then that
the artisan would consider Loctite 408 material as a form of
alkyd which is considered to be a thermosetting material.
These observations of ours with respect to the Loctite 408
data sheet are confirmed by Hawley's Condensed Chemical
Dictionary, Eighth Edition, page 250 (1971). This dictionary
defines cyanoacrylate adhesives at page 250 as being alkyl-based
adhesives having excellent polymerization and bonding properties,
and that they are used in printing environments. This is
