SL-668 hydrophobic single-component polyurethane foaming agent

Overview of SL-668 hydrophobic single-component polyurethane foaming agent

Concrete foaming agent is a specialized chemical admixture used in the production of lightweight cellular or aerated concrete, such as lightweight concrete blocks, CLC (Cellular Lightweight Concrete), or foam concrete. This material introduces stable air bubbles into the concrete mix, significantly reducing its density and increasing insulation properties while maintaining sufficient structural strength. The process involves mixing the foaming agent with water to create a foam, which is then introduced into a cement slurry, creating a lightweight and porous concrete mixture.

Features of SL-668 hydrophobic single-component polyurethane foaming agent

1. Low Density & Lightweight: By introducing countless tiny air pockets, the agent reduces the weight of the final concrete product by up to 75%, making it easier to handle and install.

2. Insulation Properties: The air-entrained structure improves thermal and acoustic insulation, reducing energy consumption in buildings.

3. Workability and Flowability: The foam enhances the fluidity of the concrete mixture, improving its ability to flow and fill complex shapes and cavities without segregation.

4. Environmentally Friendly: Lightweight concrete uses less raw material, particularly cement, which leads to reduced carbon emissions during production.

5. Durability: Despite its lightness, properly formulated cellular concrete can exhibit good mechanical properties and long-term durability.

FAQs of SL-668 hydrophobic single-component polyurethane foaming agent

Q: How is the foam generated? A: The foaming agent is mixed with water and agitated using a foam generator, producing a stable and consistent foam that is then mixed with the cement slurry.

Q: Does the use of SL-668 hydrophobic single-component polyurethane foaming agent affect the strength of concrete? A: While it reduces the density and weight, the right proportion of foam can maintain or even enhance the compressive strength of lightweight concrete, depending on the formulation.

Q: Is it suitable for all types of concrete projects? A: Concrete foaming agents are specifically designed for lightweight concrete applications. They are not typically used in standard concrete projects where high density and strength are required.

Q: Is SL-668 hydrophobic single-component polyurethane foaming agent eco-friendly? A: Many modern foaming agents are environmentally safe and do not contain harmful substances. Additionally, using lightweight concrete reduces the overall carbon footprint of a project due to less cement usage.

Q: How does the foam affect the curing process? A: The presence of foam requires careful attention during curing to ensure proper hydration of the cementitious matrix. Adequate moisture retention is crucial to achieve the desired strength and durability.
