Product Description
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.
Applications
- 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.
- 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
- 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.
- 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).
- 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.
Application Areas
Packaging & Handling
Packaging
In 50kg, 60kg, 200kg drum, or customized.
Safety and Storage
Keep in a cool and dry place and avoid storage in direct sunlight. Store in a cool, dry place. Maintain storage temperatures between 0°C and 50°C. Shelf life is 12 months in original unopened containers. It is non-hazardous substance.
Precautions
Thermal Limits: For architectural use, apply between 0°C and 50°C. Protect from freezing. For textile applications, the emulsion must undergo high-temperature cross-linking (curing) at up to 150°C to achieve a permanent bond with the fibers.
Occupational Safety: Formulated as a sustainable, non-toxic green chemical. Wear protective gloves. In case of ocular exposure, immediately flush eyes with copious amounts of water and consult a physician.
