1.Introduction:

HS-10 organic silicon waterproof agent is a sodium methyl silicon glycol as base material. It’s a small molecule water-soluble mixture, easy to be decomposition by weak acid, under the chemical reaction between carbon dioxide and water, it can produce methyl silica, finally, it forms methyl silyl-ethers (i.e., waterproof membrane) with good waterproof properties, which is not dissolved in water, also, it’s a hydrophobic material. It can seal the internal seam of cement mortar or concrete after mixing it into cement mortar or concrete, which can enhance he compactness an improve the permeability resistance. At the same time, the material in air and water vapor can be passed through the waterproof membrane, which keeps the permeability of engineering materials. This material not only has excellent waterproof and seepage control effect, but also ventilated function.

2.Advantages:
a.Non-toxic, tasteless, free of volatilization, corrosion, inflammable, pollution and easy storage.
b.Good corrosion resistance, heat or cold resistance, permeability, waterproof and vapour proof.
c.Ease of application, low construction cost, reliable function and wide application area.

3.Application Range:

According to suitable ratio, mix waterproof agent and water, which makes water based silicon. Finally, it makes waterproof mortar, which application area is:

a.External wall, undergroud engineering such as external and internal wall, retaining wall etc.

b.Water delivery and water storage construction, such as edible water pool, water tank from waterworks.

c.Roof, toilet, shower room, cave, tunnel, civil air defence engineering.

4.Main Technical Index:
Executive Standard: JC474-1999

5.Construction Request

a.Preperation method and material request: ( weight ratio)

Cement: The best is using 425# common silicon salt cement;         Water: Common drinkable tap water;

Sand: Hard particle, coarse surface, middle sand is suitable (particle diameter is 1-2mm), mud content less than 3%.

b. Waterproof mortar construction request

- Surface Treatment: Solid construction, clean it after scabbling. While finding crack, edge damage, edge failure and uneven, we should repair it with cement mortar.

- Bonding Layer Treatment: Put 2-3 mm cement paste on some layer, which makes bonding between surface and cement paste, we will not take next process untill it reached initial set.

- Waterproof Mortar Treatment: Construction in two layers, 10mm each layer, when low layer is in initial set, press tightly and make pitted surface with wood, after it, make surface layer. When surface layer is in initial set, press tightly, and make pitted surface as protective layer.

- Make Protective Layer: Make 2-3mm thickness impermeable and waterproof mortar.

- Maintenance: In exposed, maintain more than 7 days ( normal is 14 days) in normal method. If maintain under high temperature, we should make good shadow measure, and avoid evaporating water untimely.

c. Waterproof Conncrete Construction Method:

- Silicon Water Preparation: Waterproof Agent : Water = 1 : 12 - 13 (Weight Ratio)

- Construction Method: Same as common concrete construction.

6. Note

a. This product is alkaline material, we should take labour protection glass and glove while construction, which avoid directly touching skin. While liquid touch skin, we should clean it at once with water.

b. While finding prepared waterproof mortar without enough water caused by silicon, and not ease of application, we should mix silicon water to suitable ratio, not permit to add water.

While meeting rain or too wet on the underside of surface layer, its not permit to make construction. While meeting rain invasion after construction, we should check and confirm if free of waterproof effect ( drip water and find water absorption means free of waterproof), we should re spray or paint silicon water twice, waterproof function will be recoved in 1 day later, if found effect is not good, we should re make waterproof mortar.

c. This product is heat or cold resistance, we can make construction in winter, while finding organic silicon waterproof agent freezed due to special cold, it's still used after melt, effect is same.

d. This product should be sealed and stored under shadow and dry place, shelf life is 12 months.
