A large number of building materials products such as waterproof mortar, exterior wall putty, and stone protection agents are compounded with silicone additives. By relying on the water-repellent and breathable properties of silicone oil, common problems in construction such as wall seepage, stone efflorescence, and building cracking are solved.
Adding emulsified silicone oil to exterior wall putty and waterproof mortar, after construction and curing, microscopic water-repellent channels are formed, preventing rainwater from penetrating the wall interior. At the same time, it retains the channel for water vapor to evaporate outward, avoiding wall bulging and detachment, and perfectly solving the common problem of external wall leakage. Spraying silicone oil aerosol on marble and ceramic tiles for protection, the silicone oil penetrates the micro pores of the stone, blocking the erosion of rainwater and salt alkali, and preventing the stone from turning white and efflorescing.
During the production of insulation boards, silicone oil acts as a defoaming and leveling agent. The insulation layer has uniform texture without voids, and the insulation effect is more stable. Adding silicone oil to the sealant formula improves the elasticity of the adhesive, and it is less likely to break or detach under temperature changes.
The silicone oil used in building materials is mainly water-based and environmentally friendly, without irritating odors, and complies with indoor decoration environmental standards. With the explosion of the old house renovation and home decoration waterproof market, the demand for special silicone oil for building materials has rapidly increased, becoming another major civilian incremental market segment for organosilicon.
