Product Overview of Silicone Water Repellent BL-EM03
Silicone Water Repellent BL-EM03 is a high-performance low molecular weight siloxane/silane emulsion, specially formulated to deliver superior waterproof protection and substrate durability. Its formula contains siloxane and silane components enriched with excellent methyl and octyl hydrophobic groups, as well as reactive alkoxy, hydroxyl, and epoxy groups that facilitate easy condensation and hydrolysis. When Silicone Water Repellent BL-EM03 penetrates into the pores of porous materials such as brick and concrete, its active groups react with the hydroxyl groups in the substrate or undergo self-condensation, forming a dense waterproof network structure—known as a hydrophobic film. This film effectively prevents water penetration while maintaining the substrate’s permeability to gases and water vapor, ensuring breathability without compromising waterproof performance.

Key Features of Silicone Water Repellent BL-EM03
Silicone Water Repellent BL-EM03 stands out in the water repellent market with its unique low molecular structure and comprehensive performance advantages, making it ideal for diverse substrate protection scenarios:
- Deep Penetration & Strong Protection: Featuring a low molecular structure, it can deeply penetrate into the substrate surface, with a penetration depth of ≥3mm, forming a long-lasting protective layer that guards against water damage and corrosion.
- Superior Water Repellency: Significantly reduces the substrate’s water absorption rate, effectively resisting corrosion, acid rain erosion, and moisture-related damage, extending the substrate’s service life.
- Non-Impacting Aesthetics: Does not alter the substrate’s original appearance, while enhancing its anti-efflorescence ability, keeping the surface clean and intact for a longer period.
- Eco-Friendly & Easy to Use: Water-soluble and low in VOC (Volatile Organic Compounds), it is environmentally friendly and safe to handle. It can be easily diluted with water at the recommended ratio, simplifying application and reducing construction costs.
- Excellent Weather Resistance: Withstands over 960 hours of 6 kW artificial weathering testing, maintaining stable performance in harsh environmental conditions such as intense sunlight, rain, and temperature changes.
- Stable Emulsion Performance: Maintains no layering after centrifugation at 3000 rpm for 30 minutes, ensuring consistent quality and performance during storage and application.
