Manta WS111 Reactive Siloxane Emulsion

Manta WS111 is a water-borne reactive siloxane emulsion engineered for the durable hydrophobic impregnation of porous mineral substrates and advanced textile finishing.

Unlike highly alkaline siliconates, this neutral emulsion cures through a completely different mechanism. Upon penetration, the active siloxane molecules react with natural hydroxyl groups (in masonry) or fiber molecules (in textiles). This dehydrocondensation process forms a highly stable, insoluble, three-dimensional polysiloxane network, delivering exceptional water repellency while maintaining complete breathability.

Features

• Deep Penetrating Power: Highly penetrative formulation that reaches deep into the substrate, delivering exceptional water and moisture repellency.
• 100% Breathable & Invisible: Forms no surface membrane. Fully preserves the substrate’s natural appearance and crucial water vapor permeability.
• Comprehensive Protection: Dramatically reduces capillary water absorption, providing enduring protection against efflorescence, rust (rebar corrosion), and environmental staining.
• Dual-Industry Versatility: A unique molecular structure designed to excel in both architectural mass-waterproofing and high-performance textile DWR (Durable Water Repellent) finishing.

1. Architectural & Civil Engineering Protection

Infrastructure & Masonry: Robust moisture mitigation for concrete, brickwork, tunnels, dams, and subterranean structures.

Water-Retaining Facilities: Enhances impermeability in pools, water purification tanks, and wastewater containment systems.

Coating Additive: When incorporated into water-borne latex paints, it drastically reduces capillary water absorption while maintaining stable substrate bond strength.

2. Advanced Textile Finishing (DWR)

Serves as a highly effective, wash-resistant Durable Water Repellent (DWR) agent for various natural and synthetic fabrics (cotton, linen, silk, and blends).

The reactive siloxane molecules penetrate the fibers and cross-link under heat curing, forming a permanent hydrophobic finish.

How to use

1. Architectural Surface Spraying

Dilute the WS111 emulsion with clean water at a ratio of 1:10 to 1:20.

Apply evenly via a low-pressure sprayer onto highly absorbent inorganic substrates. Optimal hydrophobic performance develops after 48 hours of natural curing.

2. In-Can Addition for Water-Borne Paints

The recommended addition rate is generally 1/15 relative to the total water content of the existing coating. Mix mechanically until fully homogeneous. (Note: Add on-site; avoid long-term closed storage).

3. Textile DWR Finishing

Fully compatible with standard textile padding (pad-dry-cure) or exhaustion methods.

Recommended Dosage: 10 to 15 g/L in the finishing bath, depending on fabric weight and desired hydrophobicity.
