Silicone waterproofing agent

Silicone waterproofing agent is a new type of high-efficiency waterproof material without pollution and irritation, which is widely used in advanced countries in the world. After spraying (or brushing) this product on the surface of the building, a colorless, transparent, UV-resistant, breathable film can be formed on the surface of the building, which is imperceptible to the naked eye. When rain blows on it or encounters humid air, the water droplets will be natural. Flowing prevents the intrusion of moisture, and at the same time, it can wash away the dust on the surface of the building, so as to make the inner wall moisture-proof, mildew-proof, clean the outer wall and prevent weathering.

Nature

Silicone waterproofing agents have two properties: water-based and oily. Water-based organosilicon waterproofing agent is colorless or light yellow. When it is mixed into cement mortar, it can also act as a retarder, water reducer and enhancer. Therefore, it is suitable for the construction industry, exterior wall facing, underground engineering, antique buildings, pools, bricks and tiles, cement, gypsum products and thermal insulation materials with perlite as the main material, as well as waterproofing, moisture-proof and pollution-proof treatment of rural roofs. . The oily silicone waterproofing agent is transparent and is generally used for glaze, ceramic tiles, floor tiles, ceramics, etc. It can be diluted with some solvents and is convenient to use.

Scope of application

It is widely applicable to the internal and external walls of various buildings, especially to solve the indoor mildew problem caused by water seepage in the east and north walls of civil houses. In addition, it can also be widely used for moisture-proof and mildew-proof treatment before interior decoration, industrial plants Anti-pollution cleaning, anti-weathering, and anti-acid rain treatment of internal and external walls, as well as waterproofing projects for reservoirs, water towers, reservoirs, sewage treatment plants, and agricultural irrigation and drainage channels; for ancient buildings, stone monuments, ceramic tiles, books and archives, precision instrument rooms, and Computer room, power distribution room, warehouse, etc. are also applicable.

1. Anti-seepage and leakage prevention for building walls, especially brick walls; anti-salt precipitation and efflorescence for granite and marble walls.

2. Waterproofing of bathrooms, kitchens, enclosed balconies, etc.

3. Moisture-proof and mildew-proof for warehouses, archives, libraries, color preservation of ancient buildings and protection of cultural relics of human civilization.

4. Impregnation: roof tiles, perlite, asbestos, inorganic fabrics, thermal insulation materials, packaging cartons, fiberboards, etc.

5. It can be directly mixed with cement mortar and concrete, this agent can be used for blending water by adding 2-5 times of water.

Characteristics of permeable silicone waterproofing agent

1. It can be directly applied on the wet or dry base surface, and it has good adhesion to the base surface.

2. Anti-moisture, anti-mildew, anti-corrosion, and anti-weathering.

3. Green and environmental protection, no trace of penetration.

4. Both waterproof and breathable.

5. Convenient construction, reliable quality and safe use.

Advantage

1. High impermeability.

2. High permeability.

3. High bonding strength.

4. Strong coverage, able to cover tiny cracks.

5. The construction is simple and fast.

6. Use with a series of adhesive products, the effect is better.

7. Green building materials products.

Construction steps

1. Spray or brush

Spraying is better for rough surfaces such as concrete, cement mortar, and concrete prefabricated structures. Brushes can be used for smooth surfaces such as stone, marble, and granite.

Before use, the base surface should be carefully cleaned, floating dust and moss spots should be cleaned up, cracks, holes, etc. should be sealed and repaired in advance, and the embedding should be dense.

When in use, use a clean agricultural sprayer or brush to apply on the dry base surface (wall surface, etc.) three times vertically and horizontally, without intermittent, and spray the wall surface for 5m per kilogram. No rain shall be invaded within 24 hours after construction. The construction shall be stopped at a temperature below 4°C, and the base surface must be dry during construction. The water repellent effect can be achieved within 24 hours at room temperature, and the effect will be better after a week, and the curing time in winter will be longer.

2. Add cement mortar

Clean the base surface, clean the oil stains, floating dust, remove the peeling layer, etc., and seal the cracks with flexible materials.

Supplementary Instructions for Silicone Water Repellent

Silicone waterproofing agent is a high-performance waterproofing agent synthesized from monomethyl alkane. It has a good affinity for many building materials, especially silicate building materials. It can self-polymerize with carbon dioxide in the air to form a layer of silicone waterproof membrane, which has good water permeability. It is a high-quality, low-cost, high-efficiency waterproof material for building materials, and has been widely used in construction, house repair, building materials, exterior decoration and other industries in China.

Performance and characteristics The silicone water-repellent is a colorless or light yellow liquid, non-toxic, non-volatile, and does not contain (methanol, benzene, thinners), it is alkaline, easy to interact with carbon dioxide and form a polymer network silicone resin film . Good waterproof performance, long life, acid and alkali resistance, pollution prevention, weather resistance, no corrosion to steel bars, expansion effect, can compensate for the shrinkage of mortar and concrete, etc., because of its low price and convenient construction, it is popular among users.
