Industrial flooring




Epoxy resin based floors last longer The properties of an Epoxy resin based floor topping are governed by the type of resin/hardener binder system used, and the type and amount of filler added. Floor toppings with special properties can be formulated by selecting the most suitable binder system. Epoxy resin epoxy floorings in general exhibit the following characteristics : Low dirt and dust retention Easy cleaning Minimal maintenance costs Decorative effects Impermeability to water High abrasion resistance No gaping joints due to shrinkage Antiskid effects (imparted by dusting with highly abrasive chips] Good resistance, especiallyto Oils & fats Alkalies Acids Household chemicals Solvents Detergents, etc.
The mechanical properties of the Epoxy resin based topping are clearly superior to those of the cement mortar screed, particularly as regards flexural strength. In addition, the Epoxy resin topping offers other advantages such as better resistance to chemicals and excellent adhesion to a large variety of substrates. However, when planning to lay a new floor it is always advisable to seek the advice of our experts working for established flooring projects. We can recommend the most suitable system for a given application. The following table provides comparative figures for the mechanical properties of an Epoxy resin based topping (binder-to-silica sand ratio 1:6 pbw) and a high grade B 400 cement mortar screed :


	Epoxy Resin floor toppping	Cement mortar screed

Density	c. 2000 kg/m³	2400 kg/m³
Compressive strength	90 - 110 N/nm²	40 N/nm²
Flexural strength	25 - 35 N/nm²	5 N/nm²
Modulus of elasticity	15,000 N/nm²	30,000-40,000 N/nm²
Coefficient of linear thermal expansion	25 - 40 10⁶ cm/cm⁰C	10 - 15 10⁶ cm/cm⁰C

Factors determining the choice of floor topping

The planning stage is the best at which to decide where Epoxy resin based floor toppings are to be laid; the subfloors cansider carefully the stresses to which the floor will later be subjected, special attention being paid to t be correctly designed for strength, surface finish, evenness, etc. It is also the best stage to conhe following points:

     Mechanical stresses
a) Static loads?
b)   Dynamic loads?
    Type of traffic
a)   Foot traffic, e.g. rubber-soled shoes,
      hobnailed boots?
b)   Wheeled traffic, e.g. rubber or steel tires?
c)   Impact stresses, e.g. dropped tools?
    Indoor or outdoor site ?
    Likely variations in ambient temper-
       ature and pressure of expansion
       joints in the subfloor
a)   Normal room temperatures?
b)   Wide temperature variations?
c)   Localized zones of high or low
      temperature?
    Chemical attack
a)   Types of chemicals?
b)   concentrations?
c)   Temperature of chemical solutions?

    Duration of exposure to chemicals
a)   Splashes?
b)   Occasional exposure?
c)   Constant exposure?

    Cleaning methods
a)   Brooms?
b)   Scrapers?
c)   Water under pressure, steam, etc.?
d)   Other methods?

Intervals at which floor will be cleaned

    Safety factors required
a)   Antiskid properties
b)   Spark resistance
c)   Antistatic properties
d)   Other properties

   Appearance requirements
a)   Plain industrial floor?
b)   Aesthetic appeal needed?
c)   Other requirments
