Silane/Siloxane Water-Repellent Emulsion | Manta WS100
Manta WS100 is a water-based emulsion of silane and modified polysiloxane, used as the active waterproofing ingredient in water-based impregnating agents and as a hydrophobic primer for mineral building materials such as clay brick, clinker, sand-lime brick, natural stone and mineral renders. It is solvent-free and develops early water resistance.

- Emulsion based on silane and modified polysiloxane
- Form
- Milky white or white liquid
Overview
Manta WS100 is a solvent-free, water-based emulsion based on silane and modified polysiloxane (active content: approx. 50%). It is used as an active waterproofing ingredient for the manufacture of water-based impregnating agents and as a hydrophobic primer for mineral building materials.
WS100 penetrates well into mineral substrates and develops high water resistance rapidly after application. It maintains the natural water vapor permeability of the substrate, gives a strong beading effect, reduces surface soiling and helps to limit the efflorescence of soluble salts. It suits clay bricks, clinker, sand-lime bricks, natural stone and mineral plasters and renders, and is less suitable for dense, low-absorbency natural stone, especially limestone and marble.
WS100 and Manta WS101 are both water-based emulsions diluted before impregnation. WS100 combines silane with modified polysiloxane for mineral building materials and primers, while WS101 is a small-molecule silane emulsion designed to penetrate several millimeters into dense concrete.

Applications
- Impregnating agents: active waterproofing ingredient for the manufacture of water-based impregnating agents
- Substrate impregnation: diluted with water for clay bricks, clinker, sand-lime bricks, natural stone and mineral plasters and renders
- Hydrophobic primers: combined with a suitable polymer dispersion (hydrosol) to formulate a hydrophobic primer for mineral building materials
- Integral water repellency: in-mass addition to cementitious mixes to give integral water repellency and reduce efflorescence
Application Method
- Substrate Compatibility: Manta WS100 is an outstanding impregnating agent suitable for a wide range of mineral substrates, including clay bricks, clinker, sand-lime bricks, natural stone, and mineral plasters/renders. It is less suitable for dense, low-absorbency natural stone, especially limestone and marble.
- Dilution & Application: Dilute Manta WS100 with clean water at a ratio of 1:4 to 1:9, depending on the porosity and absorption capacity of the substrate. Apply the diluted solution liberally and evenly onto the absorbent surface using a brush, roller, or flooding method. To ensure complete coverage and avoid missed spots, a "wet-on-wet" application technique is highly recommended.
- Hydrophobic Primer Formulation: When used to formulate a hydrophobic primer, it is recommended to be applied in combination with a suitable polymer dispersion (hydrosol).
- Mass Water Repellency: For integral (in-mass) water repellency and to reduce efflorescence, an addition rate of 0.1% to 1.0% by weight of the cement content is recommended.

Packaging & Storage
Supplied in 190 kg drum and 950 kg IBC.
Safety and Storage
Temperature Sensitivity: Manta WS100 is an aqueous emulsion that is highly sensitive to frost and extreme heat. It must be stored indoors at temperatures strictly between 5°C and 40°C. Exposure to temperatures outside this range may cause irreversible emulsion breakage (phase separation).
Quality Verification: In the event of suspected frost or heat damage, the viability and homogeneity of the product must be thoroughly verified prior to application or formulation.
Storage Stability: After prolonged storage, the emulsion may undergo natural physical changes such as creaming, precipitation, or slight phase separation. Ensure the product is stirred thoroughly (homogenized) before use to restore its uniform state.
Shelf Life & Transport: 12 months when stored properly in original, unopened containers.

Frequently Asked Questions
How should Manta WS100 be diluted for impregnation?
Dilute it with clean water at 1:4 to 1:9, depending on the porosity and absorption capacity of the substrate. Apply the diluted solution liberally and evenly by brush, roller or flooding; a wet-on-wet technique is recommended to avoid missed spots.
Is Manta WS100 suitable for marble and limestone?
It is less suitable for dense, low-absorbency natural stone, especially limestone and marble. It is intended for clay bricks, clinker, sand-lime bricks, natural stone and mineral plasters and renders. Manta L310 is an alkyl silane whose TDS covers marble, granite and sandstone.
Can Manta WS100 be added directly into cementitious mixes?
Yes. For integral (in-mass) water repellency and to reduce efflorescence, the recommended addition rate is 0.1% to 1.0% by weight of the cement content.
How is Manta WS100 formulated into a hydrophobic primer?
When used to formulate a hydrophobic primer, it is recommended to combine it with a suitable polymer dispersion (hydrosol). It also serves as the active waterproofing ingredient in water-based impregnating agents.
