the aromatic odor through the facility.
2. Shelf life limitations of the resin requirerefrigerated storage below
608 F( 158 C) to extend useful life.
Table 1.7 provides comparative chemical resistance for two types of
polyester and vinyl ester resinm ortarand grouts.
1.3.2 Inorganic
Inorganic materials predate their organic counterparts, offer fewer choices,
and consequently are somewhat easiert ou nderstand. The most popular
materials are
1. Hot-pour sulfur mortars
2. Ambientlym ixed and applied silicate mortars
For years,all categorieswere referred to as “acid-proof mortars” because
their capabilities are limited to am aximum pH of 7. They are not intended
for alkaline or alternately acid and alkaline service.
