Shandong Qingdao Sealant Curing Agent, which one is better? Qingdao Dumai New Technology Co., Ltd. Qingdao Dumai New Material Technology Co., Ltd. is a high-tech enterprise that integrates research and development, production, sales, design, and construction of environmentally friendly high-performance building and industrial flooring materials. Lithium-based sealant curing agents are all nano-level materials with strong permeability, which can effectively penetrate the concrete surface and actively undergo continuous chemical reactions with the concrete. The effective components of lithium-based sealant curing agents combine with free calcium, potassium ions, and other elements that may reduce concrete strength, generating a non-expanding, non-shrinking, stable chemical copolymer—hydrated calcium silicate, which fills the capillary pores in the concrete, making the entire concrete a dense, solid, dust-free, crack-free, breathable, and colored whole. This achieves hardening, strengthening, dust prevention, waterproofing, weathering resistance, wear resistance, alkalinity resistance, chemical erosion resistance, salt resistance, oil stain resistance, and safe and environmentally friendly sealing effects. Moreover, as time goes by, the more fully the curing agent reacts with the cement, the higher the floor strength. It ensures environmental safety, durability, and resistance to pressure and wear. Concrete sealant curing agent application scope: requires a clean environment, with certain requirements for dust content in the air, but not suitable for areas that require surface coating materials. It is suitable for various ordinary concrete floors, wear-resistant floors, terrazzo floors, mortar, and other new and old concrete surfaces. For example: factories, warehouses, freight distribution centers, shopping centers, parking lots, service stations, hangars, and other floor areas.
