World Leader (cont'd) - From 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 conditions. It is not only climate but also hourly changes in weather conditions during the installation. 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. Furthermore, a high green strength (grab) is vital 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. It is adhesive handling properties and grab before cure that counts for a profitable installation. After installation, to keep the profits by avoiding “call backs”, its adequate initial bond strength, plus being sure that the adhesive does not deteriorate and later become a "time bomb" regarding outdoor weathering and durability.

Because we believe that adhesive handling properties are so important, we have developed six single component NORDOT® Adhesives for outdoor installations depending on the type of installation and method of application (spray vs. trowelling; liquid vs. mastic; etc.).

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” 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; 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.
