Product Description
Manta WS513 is a solvent-free, highly efficient aqueous emulsion of functional polysiloxanes. It is specifically engineered as a mass hydrophobic additive for phenolic resin binders used in the insulation industry.
Equivalent to: Wacker SILRES® BS 5137.
Properties
- Exceptional Hydrophobicity: Imparts outstanding, long-lasting water repellency to the finished insulation materials.
- Highly Breathable: Maintains uncompromised water vapor permeability within the mineral fiber network.
- Premium Compatibility: Exhibits excellent chemical and physical compatibility with standard phenolic resin binders.
- Process Friendly: Can be seamlessly and directly incorporated into the phenolic resin mix without requiring complex emulsification steps.
Applications
Manta WS513 is a dedicated water-repellent additive for the industrial manufacturing of bonded mineral wool products. It is highly recommended for incorporating into the binder systems of:
- Rock wool (stone wool) insulation boards and rolls.
- Glass wool insulation products.
- Other mineral-fiber-based acoustic and thermal insulation materials.
Application Method
- Mixing Procedure: Manta WS513 should be added directly into the formulated phenolic resin binder under continuous, gentle agitation.
- Recommended Dosage: The optimal addition rate is between 0.5% and 1.0% by weight, calculated strictly relative to the total mass of the phenolic resin binder.
Packaging & Handling
Packaging
In 20-25kg/ Plastic drum, 180-200kg/Iron drum
Safety and Storage
Temperature Sensitivity: Manta WS513 is an aqueous emulsion sensitive to extreme temperatures. It must be stored indoors and strictly protected from frost and excessive heat.
Storage Range: Storage temperatures must be maintained between 5°C and 40°C. Exposure to temperatures outside this range may cause irreversible emulsion breakage (phase separation).
Quality Verification: In the event of suspected frost or heat damage, the viability and homogeneity of the product must be thoroughly verified prior to application.
Shelf Life: 12 months when stored properly in original, unopened containers. It’s a non-hazardous substance for transport.
