Alkali-free solid setting agent is a new type of environmentally friendly alkali-free, chlorine-free high-performance setting agent. It has a strong function of accelerating cement solidification, significantly improves early and late cement strength, and enhances anti-seepage ability.
🛡️ Ingredients: Aluminum sulfate system, non-toxic, harmless, non-radioactive, non-corrosive, non-flammable, and non-explosive.
⚠️ Safety Tips: Avoid contact with skin and eyes; rinse with clean water if contact occurs. Wear masks and goggles when handling powder.
