Chemipat Adhesives
Imagine being faced
with the task of applying a flexible coating to a cotton fabric for the
purpose of waterproofing, and then the current coating material imparted
too great a stifness for the intended use; and yet, here was a coating
material known as rubber which was available only as large lumps. Those
early pioneers, amongst whom Charles Macintosh is perhaps the best
known, faced a daunting problem.
With today's
knowledge it must appear simple: dissolve the rubber in a suitable
solvent to gain tractability, apply as a "liquid" coating to the cotton
fabric and dry. Subsequent cutting and stitching followed by sealing the
stitching with "garment varnish" completed the production of a
relatively comfortable and yet waterproof garment. The industry fathers
would be gratified to find that the principle they established remains
unchanged but would undoubtedly be amazed at the vast array of webs,
coatings and end products found today.
