As previously indicated, adisadvantage inherent in acrylic systems is the
aromatic odor for indoor or confined space applications.
Theu rethanes ystems arei ntendedt ob em onolithicfl oors with
elastomeric properties installed in thicknesses of 1/8 to 1/4 in. (3–6 mm).
Similar to the acrylics ystems, the urethanes are intended for protection
against moderate to light corrosion environments. Standard systems are
effective at temperatures of 10–1408 F( K 24 to 608 C). High-temperature
systemsa re available for exposure to temperatures of 10–1808 F( K 24 to
828 C). Manyo ft he urethane systemsa re capableo fb ridging cracksu pt o

The monolithic urethane flooringsystems offer the following advantages:
1. Theyare easy to mix and applyusingthe pour-in-place, self-level
application technique.
2. Systems area vailable for indoor and outdoor applications.
3. The elastomeric quality of the systems provides underfoot comfort
for production line flooring applications.
4. Because of their being elastomeric, they have excellents ounddeadening properties.
5. Theyh ave outstanding resistance to impact and abrasion.

The comparative chemical resistances of acrylicand urethane systems are
presented in Table1.11.
The physical properties of acrylic systems are substantiallydifferent from
those of the urethanes. The acrylic flooringsystems are extremely hard and
should be considered too brittle for applications subjectedt oe xcessive
physical abuse such as impact from large-diameter steel pipe, steel plate,
