Description ST-40 is a new weather-resistant silicone material with strong permeability. It can penetrate into porous materials for deep modification, reshape the surface microstructure of the material, and even change the surface light reflection characteristics. This product is suitable for color enhance, polishing, repairing and renovating colored stones to enhance the aesthetic value of the stone and also gives the stone waterproof and anti-fouling functions. Compared with film-forming materials, the treatment effect of permeable materials is more natural and can better maintain the natural beauty of the stone. Attention 1. This product should be packaged in well-sealed HDPE or galvanized iron drums and stored in a cool, dark and dry place. Fireworks are prohibited in the use area and children are prohibited from touching it. 2. Before large-area construction, please be sure to conduct a small-area test. 3. Please wear special protective gloves, goggles and masks when using this product. This product generally must be diluted with a solvent before use, and the formula depends on the terminal application scenario. 4. After dilution, use a clean brush or soft cloth to dip in enough liquid and apply it evenly on the surface of the substrate to ensure that the substrate is fully absorbed, and then wipe off the remaining liquid on the surface. 5. For substrates that have been surface modified or contaminated, the use effect may be affected. 6. In order to improve the use effect, all utensils and raw materials should be kept dry and clean during preparation, and contact with moisture should be reduced. 7. After construction, ventilate at room temperature for more than 24 hours. The base material is prohibited from contacting water before the protective effect is produced.
