Funcosil WS, SNW or SNL [ultra]?
Which product replaces the familiar Funcosil SNL?
For many years, Funcosil SNL was one of the best-known Remmers products for hydrophobic facade impregnation. However, the original Funcosil SNL is no longer available as the current product in the markets concerned. Remmers has developed and introduced newer water-based products that take over this type of application.
The important point for customers throughout Europe is that the replacement does not have the same name in every country. Depending on the market, customers may encounter Funcosil WS, Funcosil SNW or Funcosil SNL [ultra]. These are not simply different labels for the old SNL, but current products with their own technical specifications.
If you are searching for the old Funcosil SNL, do not automatically assume that a product carrying the name SNL [ultra] is the same formulation. The original SNL was a different, solvent-based product. The newer products are water-based formulations.
What happened to Funcosil SNL?
The original Funcosil SNL has been discontinued as the previous generation of Remmers hydrophobic facade impregnation. It has been replaced by newer water-based products.
What makes the situation confusing is that Remmers uses different product names in different European markets. A customer in Germany may therefore search for one product name, while a customer in the Netherlands, France, Spain or another European country encounters another.
For this reason, searching only by the old product name is not always sufficient. The application, formulation, article number and current technical data sheet should be taken into account.
| Product generation | Product | Market / naming | Formulation |
|---|---|---|---|
| Previous generation | Funcosil SNL | Former product name | Solvent-based |
| Current generation | Funcosil SNL [ultra] | Used in selected European markets | Water-based |
| Current generation | Funcosil SNW | Dutch market / selected markets | Water-based |
| Current generation | Funcosil WS | Used in several European markets | Water-based |
The old SNL versus the new water-based products
One of the most important differences is the change in formulation. The original Funcosil SNL was a solvent-based silane/siloxane impregnation. The newer products WS, SNW and SNL [ultra] belong to the water-based generation.
| Characteristic | Old Funcosil SNL | Current WS / SNW / SNL [ultra] |
|---|---|---|
| Product generation | Previous generation | Current generation |
| Carrier | Solvent-based | Water-based |
| Formulation | Silane/siloxane solution | Water-based hydrophobic formulations |
| Odour | Typical solvent odour | Water-based / low-odour formulations |
| Active substance | Approx. 7% | Approx. 10% or more, depending on product |
The current products should not be presented simply as the old SNL under a different name. They represent the newer water-based generation that has replaced the previous SNL product in the relevant markets.
Why are there three different replacement names?
Remmers products are marketed through different national and regional assortments. As a result, the successor to the previous generation of facade impregnation is not necessarily presented under one identical product name throughout Europe.
This is particularly relevant when customers purchase across borders. A contractor who has previously worked with Funcosil SNL may search for exactly that name, while the current Remmers product available in his country has a different name.
- Funcosil WS
- Funcosil SNW
- Funcosil SNL [ultra]
The exact suitability of each product should always be checked against the current technical documentation for the substrate and application.
Funcosil WS, SNW and SNL [ultra]
Although the names are different, the three current products share the same general application field: hydrophobic impregnation of porous mineral building materials.
| Characteristic | Funcosil WS | Funcosil SNW | Funcosil SNL [ultra] |
|---|---|---|---|
| Water-based | Yes | Yes | Yes |
| Silane / siloxane based | Yes | Yes | Silane-based |
| Active substance | Approx. 10% | Approx. 10% | >10% |
| Solvent-free | Yes | Yes | Yes |
| Water-repellent | Yes | Yes | Yes |
| Vapour-permeable | Yes | Yes | Yes |
| UV-resistant | Yes | Yes | Yes |
| Alkali-resistant | Yes | Yes | Yes |
| PFAS-free | Yes | Yes | Yes |
These similarities explain why the three products can be considered part of the same current water-based Funcosil generation. They should nevertheless not be treated as technically identical products: application rates, packaging, technical specifications and national availability can differ.
Funcosil WS
Funcosil WS is a water-based silane/siloxane emulsion for hydrophobic impregnation. It is intended for porous mineral substrates such as brick, sand-lime brick, natural stone, mineral renders and aerated concrete.
The product is suitable for protection against driving rain, reducing water absorption, refreshing older hydrophobic treatments and subsequent impregnation of suitable mineral coatings.
- Water-based silane/siloxane emulsion
- Approx. 10% active substance
- Solvent-free
- Water-repellent
- Vapour-diffusion open
- UV- and alkali-resistant
- PFAS-free formulation
Funcosil SNW
Funcosil SNW is another current water-based silane/siloxane impregnation. It is supplied as an aqueous emulsion and contains approximately 10% active substance.
SNW is particularly relevant to customers who previously used the older SNL product but are now looking for a current water-based Remmers solution. The precise application should always be checked against the current technical data sheet.
- Current water-based product
- Silane/siloxane based
- Approx. 10% active substance
- Solvent-free
- Odourless
- Vapour-permeable
- PFAS-free
Funcosil SNL [ultra]
Funcosil SNL [ultra] is a current water-based product with its own product identity and article number. It should therefore be distinguished clearly from the discontinued classic Funcosil SNL.
The current technical information specifies more than 10% active substance. Its application areas include porous mineral facade materials, protection against driving rain, reduction of water absorption and renewal of existing hydrophobic treatments.
- Current-generation product
- Water-based formulation
- More than 10% active substance
- Solvent-free
- Water-repellent
- Vapour-diffusion open
- UV- and alkali-resistant
- PFAS-free
What does this mean if you used Funcosil SNL before?
If your previous project specifications refer to Funcosil SNL, it is important not to order a product solely on the basis of the name.
The original SNL is no longer the current product and the modern replacements are water-based products. Depending on the country, you may therefore be directed to Funcosil WS, Funcosil SNW or Funcosil SNL [ultra].
If you need to replace an older specification, compare the technical data sheet, substrate, consumption and application method before starting the work.
You may find a different current product depending on where you are located in Europe. Search for Funcosil WS, Funcosil SNW or Funcosil SNL [ultra] as well as the old product name.
