Henkel Polypoxy CR
Polypoxy CR is a solvent free high build epoxy resin protective coating which provides a chemical resistant surface for concrete and steel.
FIELDS OF APPLICATION
– internal protection of concrete or metallic storage tank, certain chemicals, oil & fuel
– chemical resistant floor and wall coating for manholes, treated sewerage lines, manufacturing units, breweries, etc
New concrete surface to be treated must be 28 days old. Ensure that the moisture content of the surface is less than 5%. The surface shall be free from dust, dirt, curing compound and laitance. The cleaning shall be done by grit/captive blasting or mechanical grinding. The concrete should be sound and any cracks, pot holes shall be repaired with Polypoxy BF* or Polypoxy NF*. prior to the application of the coating make sure that the surface is absolutely dry.
The coating can be directly applied on new concrete surface, provided the surface preparation is done thoroughly to ensure good adhesion. For old and porous concrete, prime the prepared surface with Polyprime EP@ 4-5m2/L. The coating is applied when the primer is in a tacky to semitacky condition. However, in all circumstances, the coating shall be applied within 12 hours of application of the primer. If the primer surface is left open for more than 12 hours, then a fresh coat of primer has to be reapplied.
Mix part A (resin) and part B (hardener) separately for 1 minute using a slow speed drill fitted with a paddle. Then add part B into part A and mix thoroughly for 2 - 3 minutes to achieve uniform consistency. Apply immediately after mixing.
Polypoxy CR may be applied by brush, squeegee, roller or industrial sprayer. The coating shall be applied @0.3 L/ m2 /coat to achieve a dry film thickness of 300 microns. As the coating is heavy bodied, it is advisable to apply extra coats on vertical than in horizontal, to avoid sagging of the product. Each subsequent coat shall be applied only after the previous coat dries off completely. After application the coating must be back rolled to reduce surface irregularities and improve bonding. Please contact our techinical service team for specific requirement.
Clean all equipments with a Polysolvent immediately after use. Hardened materials can be removed mechanically only. STORAGE & SHELF LIFE Store in a cool, dry place and keep away from all sources of heat and sunlight. In tropical climates, store in air condition rooms. The shelf life is up to 12 months in unopened condition and if stored as per recommendations. Excessive exposure to sunlight, humidity and UV will result in the deterioration of the quality of the product and reduce its shelf life.
