Shandong Qingdao Sealing Curing Agent: Which One is Better? Qingdao Dumai New Technology Co., Ltd. Qingdao Dumai New Materials Technology Co., Ltd. is a high-tech enterprise that integrates research and development, production, sales, design, and construction of environmentally friendly, high-performance flooring materials for construction and industrial use. Lithium-based sealing curing agents are nano-level materials with strong penetration capabilities, effectively infiltrating the concrete surface and actively engaging in continuous chemical reactions with the concrete. The effective components of lithium-based sealing curing agents combine with free calcium and potassium ions that can reduce concrete strength, generating a non-expanding, non-shrinking, stable chemical copolymer—hydrated calcium silicate—that fills the capillaries in the concrete. This process transforms the entire concrete into a dense, robust, dust-free, crack-free, breathable, and colorful entity, achieving hardening, strengthening, dust prevention, waterproofing, weather resistance, wear resistance, alkalinity resistance, chemical erosion resistance, salt resistance, oil stain resistance, and safety and environmental protection. Furthermore, as time progresses, the more thoroughly the curing agent reacts with the cement, the higher the floor strength. It ensures environmental safety, durability, and resistance to compression and wear. Concrete sealing curing agent application range: It requires a clean environment and has certain requirements for airborne dust levels, but it is not suitable for areas intended for surface coating materials. It is applicable to various types of ordinary concrete floors, wear-resistant floors, terrazzo floors, and mortar on both new and old concrete surfaces. For example: factories, warehouses, freight distribution centers, shopping malls, parking lots, service stations, and hangars, among others.
