Integral Concrete Waterproofing Admixture | Manta WS360
Manta WS360 is a water-reducible, solvent-free emulsion of organically modified silanes and siloxanes, designed primarily as a mass waterproofing admixture for freshly mixed concrete and specialized cementitious products. It resists the alkaline environment of fresh cement, reduces capillary water absorption, and can also be used for topical impregnation of cured concrete.

Overview
Manta WS360 is a water-reducible, solvent-free emulsion based on organically modified silanes and siloxanes, with an active substance content of approx. 50%. It is primarily recommended as an integral waterproofing admixture for concrete and specialized cementitious products, and it can also be used for the topical impregnation of cured concrete surfaces.
The emulsion is highly resistant to the alkaline environment of fresh cementitious matrices and has good storage and dilution stability. It significantly reduces capillary water absorption while maintaining water vapor permeability. WS360 can be used neat or, for non-load-bearing concrete, pre-diluted with clean water. Both dosage options are calculated by weight of the cement content and are given in the TDS.
Manta WS170 is the admixture to evaluate when a water-reducing effect is also needed. Manta WS180 is mainly an active ingredient for surface impregnants and primers, with integral use as an additional option. WS360 is positioned the other way around: in-mass addition first, with topical impregnation as a secondary use.

Applications
- Integral waterproofing: admixture for concrete and specialized cementitious products
- Non-load-bearing concrete: pre-diluted addition based on cement content
- Cured concrete: topical impregnation of cured concrete surfaces
Applications & Dosage
Manta WS360 is primarily recommended as an integral waterproofing admixture for concrete and specialized cementitious products.
- For Non-Load-Bearing Concrete (Diluted Use): WS360 can be pre-diluted with clean water at a ratio of 1:4 (WS360 : Water). The recommended dosage of this diluted solution is 1.0% to 5.0% by weight of the cement content.
- Standard Integral Addition (Neat Use): If using the concentrated product directly, the recommended dosage is 0.1% to 1.0% by weight of the cement content.
- Mixing Guidelines: Add WS360 directly to the gauging water or introduce it during the active mixing process. Do not pre-mix WS360 directly with other concrete admixtures prior to addition.
Packaging & Storage
Supplied in 60 kg, 120 kg plastic drums and can be customized.
Safety and Storage
Temperature Sensitivity: This emulsion is sensitive to extreme temperatures. Store indoors in a cool, well-ventilated, and dry area. Protect strictly from frost and direct sunlight. Storage temperatures must remain between 5°C and 40°C (41°F - 104°F) to prevent irreversible emulsion breakage.
Homogenization: After prolonged storage, minor phase separation or creaming may occur. Thoroughly stir or agitate the product before use to ensure complete homogeneity.
Shelf Life: 12 months in original unopened containers. Material that has passed its shelf life may still be viable, provided it passes standard quality control testing before processing. It’s a non-hazardous substance for transport.

Frequently Asked Questions
What are the neat and diluted dosage options for Manta WS360?
Used neat, the recommended dosage is 0.1% to 1.0% by weight of the cement content. For non-load-bearing concrete, WS360 can be pre-diluted with clean water at 1:4 (WS360 to water), and the recommended dosage of this diluted solution is 1.0% to 5.0% by weight of the cement content.
How should WS360 be introduced into the concrete mix?
Add WS360 directly to the gauging water or introduce it during the active mixing process. Do not pre-mix it directly with other concrete admixtures prior to addition.
Is WS360 classified as hazardous for shipping?
No. WS360 is a non-hazardous substance for transport. Protect it from frost and direct sunlight, keep storage temperatures between 5°C and 40°C, and stir or agitate it thoroughly before use if minor phase separation or creaming has occurred.
