FEATURES
Silicone emulsion GKE 50-94M (SE 50-94M)* is water emulsion of oligomethylhydridesiloxane, represents 50% emulsion of the Liquid 136-157М. Emulsion GKE 50-94M (SE 50-94M)* is water- repellent for surface and volume treatment of the porous mineral bases.
APPLICATIONS AND ADVANTAGES
-
- Emulsion GKE 50-94M serves to: impart hydrophobic (water-repellent) properties to a variety of fabrics, paper, and leather; improve humidity resistance of asbestos-cement board or gypsum cardboard, ceramics, porcelain or glass insulators, and building materials; formulate release agents for glass-forming surfaces.
- Hydrophobic coat formed on the surface after treatment with water-based emulsion does not prevent normal air change in the structure, produces no changes in the appearance of materials of construction, favors to reduction of dirt retention of face finish ,extending service life of the latter. Furthermore, it prohibits the drop in heat-insulating properties of building materials, possesses good resistance to the action of such factors as alternative freeze and thaw, and wetting and drying, UV beams, IR radiation.
- The treatment of the surface with water-repellent emulsion inhibits the growth of moss and lichen.

INSTRUCTION FOR THE APPLICATION OF THE WATER-REPELLENT EMULSION GKE 50-94М (SE 50-94M)*
The treatment of the building constructions with water-repellent can be provided in two ways:
1. Volumetric treatment, i.е. – in the preparation of concrete, cement or plaster solutions (as an additive 1.5% by weight of the binder – cement or lime), that reduces their water absorption and permeability, increases the plasticity of solutions, the strength of plaster and screed, increases frost resistance of the concretes of normal hardening regardless to their composition and the type of binder.
Introduce the emulsion with mixing water or into already prepared composition if mixed at least 20 minutes.
The studies found that the optimal concentration (commercial product) of GKE 50-94M (SE 50-94M)* in concrete or cement solutions is 1,5% by weight of cement. This amount of emulsion allows a minimal water absorption and permeability of solutions.
The tests on the concrete F 200÷300 W 6 В – 15 with water-repellent emulsion GKE 50-94М (SE 50- 94M)* proved that it is required to use 5,25 kg of emulsion GKE 50-94М (SE 50-94M)* for production of the sample volume 1 m³.
2. Surface treatment – as a coating for protection of masonry, wallboard, cement and concrete ties, limestone, porous rock, slate, tile, plaster products.
For surface treatment, add one part of water emulsion GKE 50-94M (SE 50-94M)* to ten parts of water, stir and cover the surface with obtained composition until the stop of absorption, preventing drips and leaving drops. Apply the composition with a brush or paint sprayer. Repeat the treatment after drying (in 1-2 days).
The consumption of the working solution depends on the porosity of the material and it averages 350 ml per 1 m2.
When the surface treatment protects the surface from mechanical damage, when the bulk treatment the emulsion GKE 50-94М (SE 50-94M)* is distributed throughout the entire thickness of the building material, resulting that mechanical damage to the upper layers do not affect the water-repellency of the lower layers.
SAFETY INFORMATION
Emulsion GKE 50-94M (SE 50-94M)* is physiologically harmless.
