How do I choose a silicone water repellent?

Select by substrate, delivery form and application method. The range includes emulsions, siliconates, powders and resin emulsions for integral addition or surface treatment.

Should I use a water-based or solvent-based grade?

The decision depends on substrate density, penetration target, VOC requirements and application conditions. Confirm the choice with a small substrate trial.

Are grades available for cement and gypsum systems?

Yes. Manta lists products for concrete, masonry, gypsum board, mineral binders and dry-mix mortar. Check each product TDS for dosage and mix-order guidance.

How should water-repellent emulsions be stored?

Keep containers sealed and protect emulsions from freezing and excessive heat. Follow the storage range and shelf-life statement on the product TDS.

Silicone Water Repellents

Manta produces silicone water repellents in the delivery forms used by construction-chemical formulators: silane and siloxane emulsions, siliconates, hydrophobic powders and silicone resin emulsions. Products are organized by substrate, active content and application method. Choosing by Substrate and Method Concrete and masonry treatments are selected by penetration target and application method. Gypsum and mineral binders use compatible emulsion additives for integral water repellency. Dry-mix mortar plants can evaluate redispersible hydrophobic powders. Facade paints and renders use silicone resin emulsions for water beading with vapor permeability. Siliconates provide an economical option for suitable mineral substrates. Confirm dosage, dilution, mix order and storage conditions on the TDS, then run a substrate or formulation trial before production use.
