DPM-4004 Water-based silicone emulsion

Overview

• DPM-4004 is an alkyl polysiloxane oligomer with excellent hydrophobic properties, capable of effectively preventing long-term erosion of walls by rainwater or flowing water while maintaining the “breathing” function of the substrate surface. It can be used as a waterproofing treatment for building walls or other architectural substrates.It is suitable for a wide range of substrates and maintains hydrophobic properties for an extended period after drying and film formation. With high reactivity, it is recommended for use on natural gravel, limestone surfaces, as well as cement, plaster, brick surfaces, and water-based products. It is non-toxic, odorless, non-irritating to the human body, and harmless.

• Waterproof coating on the surface of limestone

Usage Recommendations

The DPM-4004 must be diluted with water before use, at a dilution ratio of 5 to 15 times by weight, and then thoroughly mixed before application via brushing or spraying. For porous substrates, the dilution ratio should be adjusted to achieve optimal hydrophobic effects.

Cleanliness: Remove stains from the substrate surface before use; acidic or alkaline cleaning agents are prohibited. If a cleaning agent is used, rinse it off with water prior to application.

Drying: After rainfall, the material must be dried for at least 24 hours. Even if the substrate surface is rinsed with water, it still requires natural drying for 24 hours. (Drying by heating is also permissible.)

Leveling: Remove dust and foreign particles from the substrate surface, and fill any surface cracks.

remarks：

1. Regardless of the method employed, the diluent must reach saturation on the substrate surface to meet penetration requirements; for waterproofing products, a depth of 30–40 mm is required. For optimal results, it is strongly recommended to conduct a preliminary test on a small area first.
2. A single application should be effective; however, for porous substrates, a second coat may be applied after the first coat no longer provides a glossy finish.
3. A dilution solution with 8% active content per kilogram can treat a surface area of 3 m². The approximate dosage should be adjusted based on the substrate’s permeability and absorption capacity (ranging from 0.2 to 2 kg per square meter).
