result of our quarter-century head start in developing
outdoor adhesives for synthetic turf, we learned that there
is much more to selecting an adhesive than just its price, strength and
ability to stick. For example, the adhesive must be practical to handle
under widely variable weather conditions, and in sub-freezing to hot
desert temperatures. It is not only climate that has
an effect, but also hourly changes in weather conditions during the
installation. Hence, we believe that selecting an adhesive based merely upon its
"strength", plus other indoor laboratory testing is a waste because
even on the same day, an installation is different at 7:00 a.m. vs. 11:00
a.m. vs. 3:00 p.m. etc., as the sun rises and sets.
Because "installation time is money",
installers can’t wait for ideal weather but instead need an adhesive that
they can use when it is hot, cold, damp, dry, windy, high humidity, low
humidity, etc. Additionally, it’s vital that the
adhesive have a high "Green Strength" (high grab) in order to
overcome the troublesome forces of “wind lift”; edge curl; creep;
wrinkling; surface buoyancy from unexpected rain; expansion and/or
contraction due to surface temperature changes from sunlight, shadows and
passing clouds, etc.
outdoor installation requires an adhesive that has an “installer-friendly"
working window; high green strength; and excellent handling properties
before it cures, regardless of the weather. Furthermore,
to keep the profits after cure, it’s not only a good
initial bond but also avoiding call backs by using adhesive with
proven long term outdoor durability.
Because we believe that adhesive handling properties are so important, we
have developed several single component NORDOT® Adhesives for
outdoor installations depending on the type of installation and method of
application (spray vs. troweling; Newtonian vs. Thixotropic liquid; glue
box; etc.). Some of our new "4-Series" of adhesives even extend the installation season
through the winter by making them easier to use in cool/cold weather.
