- Can be applied onto 7 to 10 day old concrete after adequate preparation and where substrate has tensile bond strength in excess of 1.5 MPa (218 psi).
- Resists a very wide range of organic and inorganic acids, alkalis, amines, salts and solvents.
- Similar coefficient of thermal expansion to concrete allowing movement with the substrate through normal thermal cycling. It will perform and retain its physical characteristics through a wide temperature range from -40°F (-40°C) up to 248°F (120°C).
- Bond strength in excess of the tensile strength of concrete, concrete will fail first.
- Behaves plastically under impact; deforms but will not crack or debond.
- High abrasion qualities result from its pure silica aggregate structure.
- Highly resistant to fungi and mold growth.
WHERE TO USE
PUR-CLUM floors are primarily used to protect concrete substrates. Typically used in food processing plants, wet & dry process areas, freezers & coolers, dairies, breweries, wineries, distilleries, laboratories, chemical process plants, pulp and paper plants, warehouses and storage areas.
IMPORTANT NOTE: PROPERTIES @ 73°F (23 °C) and 50% R.H. Times are approximate and will be affected by changing ambient conditions, especially changes in temperature and relative humidity. The indicated mileage is calculated for flat surfaces. A porous or imperfect surface will require more material in order to cover the same mileage. *
