The common problems such as water seepage, efflorescence, and mold on the exterior wall plaster, stone protective paint, and waterproof mortar coating are prominent. The water-repellent coating constructed by water-based emulsified silicone oil not only has the dual characteristics of waterproofing and water vapor discharge but also avoids the drawbacks of traditional solvent-based waterproof additives, which have strong odors and poor air permeability. Water vapor trapped inside the wall is prone to cause bulging and detachment. The water-based silicone oil, with water as the dispersing medium, has low VOC and no odor, and forms microscopic hydrophobic channels after curing, preventing rainwater from penetrating the wall. The internal moisture of the wall can be evaporated outward, thus completely preventing wall mold and stone whitening and efflorescence.
Adding silicone oil to marble and tile protective coatings, the liquid penetrates the micro pores of the stone to form a long-lasting waterproof film, blocking the erosion of salt and alkali rainwater. The coating of true stone paint combined with water-repellent silicone oil enhances the water resistance of the wall surface, and no water streaks will appear even after heavy rain. The product has strong compatibility in construction and can be directly mixed with water-based emulsions and inorganic silicate coatings. The high alkaline system is stable and does not separate.
The demand for home decoration waterproofing, ancient building restoration, and warehouse exterior wall coatings is continuously increasing. The cost advantage of domestic water-based silicone oil water-repellent agents is obvious. They can replace imported solvent-based waterproof additives and promote the comprehensive green transformation of building coatings.
