World Leader (cont'd) -
As a
result of our quarter century head start in developing sophisticated
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. 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 upon its
high strength, plus other indoor laboratory testing is a waste because
even on the same day, an installation is different at 7 AM vs. 10 AM vs. 1
PM, 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.
A
profitable outdoor installation requires an adhesive that has a “wide
outdoor working window”; a 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 adhesives even extend the installation season
by making them easier to use in cool/cold weather.
For
indoor installations, we prefer a new generation of one-part
urethane adhesives like our NORDOT® Adhesive #116F and NORDOT®
Adhesive #113D. In order to obtain negligible adhesive odor during indoor
installation, we had to reduce but not eliminate green strength. These
adhesives are not “oily and slippery” like most adhesives but instead
develop some "stickiness" after spreading. They also give a strong
elastomeric bond after they cure. Bonding: hardwood floors to wood or
concrete subfloors; urethane/rubber tiles and roll goods; synthetic turf
and carpet are examples where these adhesives are being successfully used
indoors.
We also expect high
use of NORDOT® Adhesive #116F and NORDOT® Adhesive
#113D as environmentally friendly adhesives for fighting harmful
mold, mildew growth and odor in climates and/or buildings that have
warm, humid and damp conditions where mold and fungi are now or could be a
problem. They are low hazard; VOC Compliant; and do not contain flammable
or toxic solvents or water.
