ALOS-SILI-209 is a solvent-soluble, fast-curing reactive silicone resin. It provides a colorless, water-repellent finish for mineral construction materials. And it is also suitable for hydrophobing and moisture-proof treatment of cement, marble, paper, textile fabrics, metals, glass, ceramics, wood and wood products, leather, and more. In addition to water repellency, it imparts a shine to the treated substrate.

Usage
ALOS-SILI-209 is typically applied as a dilute solution. To prepare, dilute the product with solvents such as acetone or methyl ethyl ketone, stirring gently until fully mixed. The level of dilution depends on the substrate and the desired surface properties; a common ratio is 1 part ALOS-SILI-209 to 4 parts solvent.
Curing: Coatings of ALOS-SILI-209 are generally heat-cured to develop optimal water-repellent or release properties. Catalysts can be used to accelerate the curing process.
Storage and Handling
- Store in original, tightly sealed containers in a cool, dry place, away from direct sunlight.
- Use appropriate safety measures, including gloves and safety goggles, when handling the product.
