Hydroxy-Functional PDMS Emulsion | Manta EH102
Manta EH102 is a reactive water-based emulsion of hydroxyl-functional polydimethylsiloxane, used as a water-repellent mass admixture for cementitious products such as pavers, precast elements and dry-mix mortars and as a performance additive for silicone resin renders and plasters. Its silanol groups bond chemically with the substrate for durable integral waterproofing.

Overview
Manta EH102 is a reactive water-based emulsion of hydroxyl-functional polydimethylsiloxane (PDMS / OH-Polymer). It serves as a water-repellent admixture for cementitious materials and as a performance-enhancing additive for silicone resin-based renders and plasters.
Its active silanol groups react chemically with hydroxyl-functional sites on the substrate, pigments and cement hydrates, giving long-lasting, integral waterproofing without compromising the material's natural breathability.
EH102 differs from Manta EH101, a methyl hydrogen polysiloxane emulsion with Si-H bonds that cross-link under catalysts or heat and that is used in gypsum, textile and glass fiber treatment.
Key Features
- Good water repellency and strong beading (lotus effect) on cured mortars and dried renders
- Active silanol groups react chemically with the substrate, pigments and cement hydrates
- High water vapor permeability
- Increases the UV resistance of silicone resin renders when combined with silicone resin emulsions
- Can be used as supplied or diluted in water

Applications
- Silicone resin renders and plasters: synergistic performance enhancer when formulated with silicone resin emulsions, giving high water repellency and beading, high water vapor permeability and increased resistance to UV degradation
- Cementitious admixtures: waterproofing mass-admixture for integral waterproofing of cement-based products such as concrete paving blocks, precast elements and dry-mix mortars
Application Guidelines & Dosage
- Preparation: Manta EH102 can be used directly as supplied or pre-diluted. When diluting, slowly add deionized water under gentle agitation. (Note: If the diluted product is stored, a suitable biocide/preservative may be required to prevent microbial growth.)
- Dosage for Renders: For optimal performance in exterior silicone resin plasters, an addition level of 0.5% to 2.0% by weight is recommended.
- Dosage for Cementitious Mixes: When utilized as an integral admixture, the recommended dosage is 0.25% to 1.0% by weight, based on the dry weight of the cementitious mixture (equivalent to 0.125% to 0.5% active silicone ingredients).
- Manta EH102 releases no volatiles during reaction.

Frequently Asked Questions
How is the dosage of Manta EH102 set for renders and cementitious mixes?
In exterior silicone resin plasters the recommended addition level is 0.5% to 2.0% by weight. As an integral admixture the recommended dosage is 0.25% to 1.0% by weight, based on the dry weight of the cementitious mixture, which corresponds to 0.125% to 0.5% active silicone ingredients.
Can EH102 be diluted before use?
Yes. It can be used directly as supplied or pre-diluted by slowly adding deionized water under gentle agitation. If the diluted product is stored, a suitable biocide or preservative may be required to limit microbial growth.
When should I choose EH102 instead of Manta EH101?
EH102 is a hydroxyl-functional PDMS emulsion (active content: Approx. 50%, pH 6.0-7.0) whose silanol groups bond chemically to the substrate and cement hydrates, which suits silicone resin renders and cementitious admixtures. EH101 is a methyl hydrogen (Si-H) emulsion (pH 4–6) that cross-links under catalysts or heat and is used in gypsum, textile and glass fiber treatment.
