Application Details
  • SILRES® POWDER D is a high-quality specialty product for enhancing the water repellency and water resistance of non load-bearing precast concrete products or mineral construction material mixes, e.g. premixed plasters, joint mortars and powder paints.
    • Properly formulated products exhibit:
    • Low water absorption coefficients
    • Excellent droplet effect
    • Low soiling tendency
    • Durability
  • SILRES® POWDER D can be used in both dry powder and liquid systems.
  • To produce non load-bearing precast concrete products or mineral construction material mixes such as premixed plasters, joint mortars or powder paints mix SILRES® POWDER D with the other dry materials using suitable equipment.
  • Very good water repellency and durability can be achieved with 0.1-0.5% based on the dry weight. After sufficient water has been added, mortars can be mixed by hand or machine. Since mixing by hand only generates low shear forces, it is best to allow the mixture to mature by leaving it to stand for 5 minutes, and then to stir it again.

Storage & Handling

Storage Information
  • SILRES® POWDER D should be stored in a cool place and protected against moisture.
  • Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
  • If the product is stored under pressure, in damaged or fairly long opened packaging, the powder can tend to caking.
  • Blends of SILRES® POWDER D with hydraulic binders, fillers and pigments have better storage stability because these substances prevent caking. However, blends of this type still have to be protected against humidity.
