Impregnation of low-fired ceramic products with silicones

Water rolls off ceramic roof tiles that have been impregnated with silicone resins.

Roof tiles, floor tiles and planters made of clay ceramics are exposed to moisture and temperature fluctuations on a daily basis. In addition to efflorescence, water ingress can also lead to the formation of moss and frost damage, which can affect the appearance, quality and useful life of the products. With SILRES® BS silicone products, we offer high-performance solutions for the hydrophobic impregnation of low-fired ceramic products. SILRES® BS provides lasting protection against water ingress, salts, and dirt, while maintaining water vapor permeability and, consequently, breathability.

Product characteristics

Siliconate and a solvent-free, water-dilutable concentrate based on silane/siloxane

The hydrophobic impregnation with SILRES® BS penetrates deep into the low-fired ceramic product (orange dots), providing reliable protection against moisture and dirt while maintaining water vapor permeability.

Advantages:

  • Effective protection against water, salts, and dirt
  • High water vapor permeability
  • High frost resistance

Applications:

  • Roof tiles
  • Facing bricks
  • Floor tiles
  • Planters

FAQs on the impregnation of low-fired ceramic products

Hydrophobic impregnation with SILRES® BS provides lasting protection against water ingress and frost damage, as well as against salt efflorescence and moss growth. At the same time, it maintains its water vapor permeability and, consequently, its breathability.

SILRES® BS penetrates deep into the pores of the substrate without blocking them. In contrast to film-forming systems, this preserves vapor permeability and breathability

SILRES® BS is suitable for roof tiles, facing bricks, floor tiles, and planters. Applying the product during the production process ensures uniform and long-lasting protection

The ceramic products are dipped in or sprayed with the diluted water-repellent agent after firing. This retains the natural appearance while providing maximum protection and long-lasting durability.
