Q&A

Q1: What is the purpose of using a defoamer in construction materials?

A: Defoamers are added to mortar, self-leveling, and grout systems to quickly collapse and prevent air bubbles from forming. This not only improves the surface finish by reducing issues like oil bleaching and black spots, but also enhances the overall density and durability of the product. Q2: What are the key benefits of using JTBON® defoamers?
Q2: JTBON® defoamers offer several advantages:

A: Rapid and Effective Foam Suppression: They quickly break bubbles and provide long-lasting anti-foaming effects. Temperature Stability: They perform reliably under both high and low temperature conditions. Enhanced Appearance: By minimizing foam and surface defects, they ensure a smoother, more uniform finish on cement-based and gypsum-based systems.
Q3: How should the defoamer be dosed and stored?

A: Generally, a recommended dosage of between 0.02% to 0.2% (by weight) is effective, but the optimal amount should be fine-tuned based on specific formulations and operating conditions. The product should be stored in a cool, dry place away from direct sunlight and moisture, ensuring a stable shelf life (typically up to 12 months when properly stored).
