Cationic Silane/Siloxane Emulsion | Manta WS400

Manta WS400 is a solvent-free cationic emulsion of reactive silanes and modified polysiloxanes (approx. 50% active, pH 4.0-6.0) used to formulate water-based impregnators for porous mineral substrates such as brick, clinker, natural stone and renders. Comparable to Wacker SILRES BS 4004, its cationic substantivity gives fast early water resistance on surfaces.

Manta WS400 is a solvent-free cationic emulsion based on reactive silanes and modified polysiloxanes.

Engineered as a premium, cationic-enhanced alternative to Wacker SILRES® BS 4004, specifically optimized for high-performance surface impregnation.

Properties

Exceptional Hydrophobicity: Delivers immediate and super-hydrophobic protection.

Highly Breathable: Maintains uncompromised water vapor permeability of the substrate.

Rapid Effectiveness: Develops high early water resistance extremely fast due to cationic surface substantivity.

Pronounced Beading Effect: Generates a strong surface water droplet roll-off (lotus) effect.

Deep Penetrating Power: Excellent depth of penetration into mineral capillary networks.

Eco-Friendly: 100% solvent-free, water-borne formulation.

Manta WS400 is utilized as a highly active, super-hydrophobic agent for the formulation of premium water-based impregnators and surface treatments.

Application Guidelines

Manta WS400 is highly suitable for various porous mineral substrates, including fired brick, clinker, sand-lime brick, natural stone, and mineral renders/mortars.

• Dilution Ratio: Dilute WS400 with water at a ratio of 1:4 to 1:9 depending on the substrate’s absorption capacity.
• Application Technique: Apply the diluted solution generously and evenly using a brush, roller, or flooding method. A “wet-on-wet” application technique is highly recommended to ensure complete, uninterrupted coverage.

Crucial Formulation & Mixing Rules

1. Water Quality: It is highly recommended to dilute WS400 with deionized or purified water. Hard water containing high levels of calcium and magnesium ions may compromise the emulsion’s dilution stability.
2. Dilution Sequence (CRITICAL): To avoid emulsion shock or phase inversion, always add the water slowly to the WS400 emulsion under continuous, gentle agitation. Strictly prohibit adding the concentrated emulsion directly into a large volume of water.
3. Compatibility Warning: WS400 is a cationic system. It is primarily designed to be applied as a stand-alone aqueous dilution. If compounding with other polymer dispersions is required, strict compatibility testing must be conducted. Never mix with anionic emulsions or additives, as immediate coagulation (flocculation) will occur.
4. Application Restriction (CRITICAL): Due to its highly substantive cationic nature, WS400 is designed exclusively for topical/surface application. DO NOT use as an integral admixture (mass hydrophobation) in fresh cement or concrete, as immediate coagulation will occur.
