Silicone-Based pH Adjuster for Paints | Manta WS168

Manta WS168 is an aqueous methylsiliconate solution (approx. 50% active, pH 13.0-14.0, specific gravity approx. 1.4) used as a silicone-based pH adjuster in waterborne emulsion paints, replacing volatile amines such as AMP-95 or ammonia. Comparable to Wacker SILRES BS 168, it is solvent-free and also raises the dried film's water repellency.

Manta WS168 is a highly concentrated, water-based, and completely solvent-free methylsiliconate solution. It functions as an advanced, silicone-based pH-adjuster specifically formulated for waterborne emulsion paints. Unlike conventional organic amines, it not only neutralizes and stabilizes the system’s pH but also actively contributes to the ultimate performance of the dried coating film.

Performance equivalent to Wacker SILRES BS 168.

Properties

1. Exceptional pH Stability: Effectively buffers and maintains the target pH of emulsion paints, ensuring outstanding long-term storage stability without pH drift.
2. Upgraded Water Resistance: The unique silicone backbone integrates into the coating matrix, boosting the overall water repellency of the final paint film—a significant advantage over standard volatile amines.
3. Enhanced Coating Durability: Contributes to improved mechanical resistance and scrubability of the dried architectural coatings.
4. Eco-Friendly & Safe: 100% solvent-free and VOC-compliant, making it the ideal pH neutralizer for formulating ultra-low VOC and exceptionally low-odor premium interior and exterior paints.

Manta WS168 is designed as a specialized auxiliary agent for the paint and coatings industry. It is highly recommended to replace conventional volatile amines (such as AMP-95 or ammonia) or harsh inorganic bases. It is perfectly suited for high-end waterborne architectural paints, plasters, and primers where strict VOC regulations, low odor requirements, and enhanced film properties are paramount.

Formulation Guidelines

To ensure safe handling and optimal performance within the coating matrix, please adhere to the following guidelines:

1. Pre-Dilution: For ease of application and to prevent localized pH shocks (alkaline burns) to the polymer emulsion, it is strictly recommended to pre-dilute Manta WS168 with water at a ratio of 1:3 (1 part WS168 to 3 parts water) prior to addition.
2. Addition Method: Always incorporate the diluted solution slowly under continuous and adequate stirring to avoid local high pH spikes.
3. Dosage: The exact dosage depends heavily on the specific paint formulation and the initial pH of the binder system. Add the diluted Manta WS168 incrementally until the target pH is achieved (e.g., pH 9.5 is typical for standard architectural emulsion paints).
