Silicone Knowledge - What are the key characteristics of silicone waterproof agents?

2025-03-31

As a high-performance building material, silicone waterproof agent exhibits multiple characteristics across six core dimensions:

1. Waterproof Performance

Coexistence of Hydrophobicity and Breathability:

By penetrating the substrate to form a network-like silicone resin film, a "lotus leaf rolling water droplet" effect is produced on the surface, preventing the penetration of liquid water while allowing water vapor to escape, achieving a dynamic balance between waterproofing and breathability.

Improved Seepage Resistance Grade:

Incorporating it into cement mortar or concrete can improve seepage resistance by more than 4 times, with a water permeability pressure ratio of up to 320% and a water absorption rate of less than 65% in 48 hours.

2. Durability

Ultra-Long Service Life:

The waterproof layer lifespan can reach 10-15 years. It is resistant to acids and alkalis, weathering, and salt efflorescence, and shows strong adaptability to ultraviolet light, high temperatures (-30℃ to 90℃), and freeze-thaw cycles.

Chemical Corrosion Resistance:

It has excellent resistance to acid rain, oil stains, and salt spray, protecting the substrate from erosion and suitable for harsh environments such as industrial plants and wastewater treatment plants.

3. Material Compatibility

Wide Substrate Adaptability:

It has strong affinity with silicate materials (concrete, bricks, tiles, stone) as well as wood and ceramics, forming a stable protective layer through chemical bonding.

Repair and Covering Capabilities:

It can cover micro-cracks less than 0.3mm and has a penetration reinforcement effect on loose substrates, without affecting the appearance and texture of the substrate.

4. Environmental 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 building material standards, and are suitable for indoor and cultural relic restoration scenarios.

Biological Protection Function:

It prevents mold, algae, and moss growth, effectively solving microbial erosion problems in basements, libraries, and other places.

5. Construction Advantages

Flexible Construction Methods:

It supports various processes such as spraying, brushing, impregnation, and incorporation into cement. It can be directly applied to damp surfaces and can also be used with antifreeze agents for winter operations.

Fast Curing Efficiency:

A waterproof layer is formed at room temperature in 24 hours, with initial setting in 2 hours, and able to withstand light trampling after 6-8 hours, significantly shortening the construction period.

6. Economy

Comprehensive Cost Advantages:

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

Reduced Maintenance Costs:

Reduces problems such as steel bar rust and insulation layer failure caused by leakage, extending the overall service life of the building.

Expanded Application Scenarios: In addition to conventional building waterproofing, it can also be used in special scenarios such as moisture-proof (anti-static) in precision instrument rooms, seepage prevention in agricultural irrigation canals, cultural relic protection (such as salt damage prevention of Mogao Grottoes murals), and corrosion prevention of photovoltaic panel bases. Note: Avoid contact with active metals such as zinc/aluminum. Use plastic containers for storage.
