Selecting Epoxy Resin for Flooring
There are thousands
of possible combinations of epoxy resin polymer, curing agents and aggregates
for use in the epoxy flooring systems. Each combination offers a different
performance property.
Much of the decision of which system to use is based on what type of surface
you plan to coat, and on the environment of the area to be coated. Whether
you want to paint your garage floor (using some epoxy paint) or coat a large
industrial hall it is essential that the designer prioritizes the performance
requirements before selecting materials for a particular epoxy flooring application.
Basically, we can classify epoxy resins as:
100% solids, solvent-based
resins, and emulsions.
Resins that are 100% solids refer to the fact that all the material in the
resin is used in the curing phase and becomes solid epoxy.
The solvents in resins evaporate during the curing cycle, they can be smelly
for a period of time, and in some cases are a fire hazard.
Emulsion resins primarily contain water as the carrier with small amounts
of solvent. These materials are nonflammable, have much less smell, and are
recommended for interior use.
Resins that are 100% solids can be roughly classified as:
1. Semi-rigid
Biphenyl A epoxy
Used for high
traffic areas, automotive service areas, impact areas, and floors that must
stand up to acid or other chemicals
2. Novolac/Bisphenol
F epoxy
Used for
applications under more severe chemical exposure, high acid / chemical handling
areas, higher temperature areas, lower temperature areas (such as refrigeration
or freezer floors), coatings for high impact floors such as industrial or
manufacturing environments
100% Solids epoxy
coatings are typically used in commercial and industrial settings. They provide
the highest level of durability and resistance. However, they are more costly,
and more difficult to apply than epoxy coating products that have a lower
percentage of epoxy solids.
