As a high-performance building material, silicone waterproofing agent has multiple characteristics reflected in the following six core dimensions:


1. Waterproof performance

Coexistence of hydrophobicity and breathability:

By penetrating the substrate to form a mesh silicone resin film, the surface produces a "lotus leaf rolling water droplet" effect, preventing liquid water from penetrating, while allowing water vapor to escape, achieving a dynamic balance between waterproofing and breathability.

Improved impermeability:

Adding it to cement mortar or concrete can improve the impermeability by more than 4 times, the water permeability pressure ratio reaches 320%, and the 48-hour water absorption ratio is less than 65%.

2. Durability

Extremely long service life:

The waterproof layer has a life of up to 10-15 years, is resistant to acid and alkali, weathering, and salt precipitation, and has strong adaptability to ultraviolet rays, high temperature (-30℃ to 90℃) and freeze-thaw cycles.

Resistant to chemical corrosion:

It has excellent resistance to acid rain, oil pollution, salt spray, etc., protects the substrate from erosion, and is suitable for harsh environments such as industrial plants and sewage treatment plants.

3. Material compatibility

Wide substrate adaptation:

Strong affinity with silicate materials (concrete, bricks and tiles, stone), wood, ceramics, etc., forming a stable protective layer through chemical bonds.

Repair and covering ability:

It can cover fine cracks below 0.3mm, and has a penetration and reinforcement effect on loose substrates, while not affecting the appearance and texture of the substrate.

4. Environmental protection characteristics

Low VOCs and non-toxic formula:

It does not contain harmful substances such as methanol and benzene. Water-based products achieve zero emissions, meet environmental protection building materials standards, and are suitable for indoor and cultural relics restoration scenes.

Biological protection function:

It is mildew-proof, algae-proof, and moss-proof, effectively solving the problem of microbial erosion in basements, libraries and other places.

5. Construction advantages

Flexible construction methods:

It supports a variety of processes such as spraying, brushing, dipping and cement incorporation. It can be directly constructed on a wet base surface or used in winter with antifreeze.

Fast curing efficiency:

A waterproof layer is formed in 24 hours at room temperature, initial setting in 2 hours, and can withstand light trampling in 6-8 hours, greatly shortening the construction period.

VI. Economical

Comprehensive cost advantage:

The unit price of the material is 30-50 yuan/kg, and each kilogram can treat a 5-10㎡ base surface. The comprehensive cost is only 1/3 of that of traditional waterproof materials.

Reduced maintenance costs:

Reduce problems such as steel bar corrosion and insulation layer failure caused by leakage in buildings, and extend the overall service life of the building.

Application scenario expansion: In addition to conventional building waterproofing, it can also be used for moisture-proof (anti-static) precision instrument rooms, anti-seepage of agricultural irrigation channels, protection of cultural relics (such as salt damage prevention of Mogao Grottoes murals), anti-corrosion of photovoltaic panel bases and other special scenarios. Be careful to avoid contact with active metals such as zinc/aluminum, and use plastic containers for storage.
