Manta WS600 Silicone Resin Emulsion

Manta WS600 is a solvent-free aqueous emulsion of a highly reactive, modified polysiloxane resin. It is specifically engineered to serve as the primary binder or co-binder in the formulation of high-performance exterior architectural coatings and plasters.

Equivalent to Wacker SILRES® BS 60

Properties

• Exceptional Water Repellency: Delivers superior, long-lasting moisture protection to the coating system.
• Highly Breathable: Ensures extremely high water vapor permeability, allowing the masonry to “breathe”.
• Aesthetic Preservation: Exhibits exceptionally low dirt pick-up, keeping exterior facades clean for years.
• Early Rain Resistance: Rapidly develops early water resistance shortly after application.
• Robust Film-Forming: Forms a durable, microporous silicone resin network.
• High Alkali Resistance: Perfectly stable in high-pH environments, making it fully compatible with silicate-based systems.
• Eco-Friendly: 100% solvent-free, water-borne formulation.

Manta WS600 acts as a core hydrophobic binder in silicone resin paints and plasters. Systems formulated with WS600 achieve the ideal balance of protecting against driving rain while maintaining maximum vapor transmission. Furthermore, due to its outstanding alkali resistance, it is highly recommended as a modifying co-binder for sodium silicate paints (mineral paints) to drastically improve their water repellency.

Formulation Guidelines

During the manufacturing process, Manta WS600 is typically incorporated into the water-based coating formulation at the following dosages (calculated by weight relative to the total formulation):

Silicone Resin Paints: 4.0% – 10.0%

Silicone-Modified (Reinforced) Acrylic Paints: 2.0% – 4.0%

Silicone Resin Plasters / Renders: 2.0% – 6.0%

SiSi Plasters (Silicate/Silicone Hybrid Renders): 2.0% – 4.0%

Formulator’s Tip: To achieve an outstanding surface water-beading (lotus) effect, we highly recommend incorporating 1% – 3% of Manta WS136 into the final coating formulation.
