High-efficiency organic silicon building waterproofing and penetrating waterproofing agent, referred to as organic silicon waterproofing agent, is a new type of water-soluble waterproofing agent made from a variety of fatty acids and more than a dozen inorganic materials through high-temperature chemical reactions using the most advanced production technology. The product generates methyl silane under the action of water and carbon dioxide, and further condenses into a polymer compound network silicone resin film, which has extremely strong permeability, obvious hydrophobic effect, quick effect and long-lasting. The water droplets will disappear naturally on the parts sprayed with it, as if water droplets fell on the lotus leaf. It is non-toxic, tasteless, non-volatile, non-flammable, and non-polluting. Compared with traditional organic silicon, it can be sprayed, painted and brushed directly on concrete, stone, brick and various silicate products and walls. The original style of the building has achieved the effects of waterproofing, preventing moss, salt and frost, mildew, and pollution, improving weathering resistance, acid rain resistance, penetration corrosion and carbonization resistance, and extending the life of concrete walls and products. And can be mixed with cement to form a hydrophobic mortar, which is used to make waterproof cement products and waterproof cement plaster layers. It is a practical, simple and low-cost new waterproof material.
