Shandong Qingdao Sealing Curing Agent - Which is the Best? Qingdao Dumai New Technology Co., Ltd. Qingdao Dumai New Materials Technology Co., Ltd. is a high-tech enterprise that integrates R&D, production, sales, design, and construction of environmentally friendly high-performance building and industrial flooring materials. Lithium-based sealing curing agents are all nanomaterials with strong penetration capabilities, effectively infiltrating the concrete surface and actively engaging in sustained chemical reactions with the concrete. Among them, the effective components of lithium-based sealing curing agents react with free calcium, potassium, and other ions that can reduce concrete strength, generating a non-expanding, non-shrinking, stable chemical copolymer—hydrated calcium silicate—that fills the capillary pores in the concrete. This process transforms the entire concrete into a dense, solid, dust-free, crack-resistant, breathable, and colorful entity, achieving hardening, strengthening, dustproofing, waterproofing, weathering resistance, wear resistance, alkali resistance, chemical erosion resistance, salt resistance, oil stain resistance, and a safe and environmentally friendly sealing effect. As time progresses, the more fully the curing agent reacts with the cement, the higher the flooring strength. It ensures environmental safety, durability, and resistance to compression and wear. Concrete sealing curing agent - Application Range: It requires a clean environment with certain limits on dust levels in the air, but is not suitable for areas that require surface coating materials. It is applicable to various ordinary concrete floors, wear-resistant floors, terrazzo floors, mortar, etc., on both new and old concrete surfaces. For example: factories, warehouses, freight distribution centers, shopping malls, parking lots, service stations, hangars, and other floor areas.
