PE-CREXT

Extreme chemical resistant epoxy

PE-CREXT is a high-built solvent less two components epoxy novalac coating system designed for severe service coating. It exhibits very good finish and chemical properties. It exhibits very good solvent and chemical resistance. It is suitable for use in direct exposure in manufacturing facilities, warehouses, laboratories, dairies, breweries, chemical plants, paper mills, food processing and pharmaceutical manufacturing.

Advantages

  • Dense surface, resistant to bacteria and moisture and easy to clean
  • May apply several layers on itself
  • Contains no solvent, allowing for interior application without harmful odors
  • Excellent adhesive properties, allowing application on other firm and hard coating, as well as a good bond to the substrate
  • Superior chemical and solvent resistance
  • Exceptional abrasion resistance

Technical Data

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. *
