Ordinary acrylic and epoxy coatings will start to fade, powder, and crack after 3-5 years of outdoor use. The solid phenolic silicone resin oil cold bonding modification process significantly enhances the coating's resistance to ultraviolet rays and temperature extremes, and is widely used for steel structure anti-corrosion and exterior wall real stone paint coating. No need to set up high-temperature reaction equipment. During the paint mixing stage, sheet-like silicone resin can be directly added, which perfectly blends with the conventional resin without layering or precipitation.
The bond energy of the silicon-oxygen bond is much higher than that of carbon-chain resins. The modified coating can withstand -40℃ to 200℃ cold and hot cycles. The artificial accelerated aging duration exceeds 1800 hours. The outdoor wall forms a hydrophobic and breathable protective layer. Rainwater washes away dust, achieving long-term self-cleaning. The wall is less likely to accumulate dirt or develop alkali spots; when added to the surface paint of construction machinery, it can resist acid rain and snow salt corrosion, doubling the equipment's rust prevention period.
After domestic coating enterprises adopted IOTA 6217 silicone resin to modify exterior wall coatings, the outdoor service life was extended from 5 years to over 10 years. The winning rate of high-end real estate exterior wall coating projects increased by 30%. Currently, weather-resistant silicone modified coatings have become the core of the engineering coating competition, and the demand for silicon resin oil for supporting coatings continues to increase. Domestic silicone resin gradually breaks the monopoly of overseas products.
