Qingdao Shandong Sealant Curing Agent Which One is Good? Qingdao Dumai New Technology Co., Ltd. Qingdao Dumai New Material 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 sealant curing agents are all nano-level materials with strong penetration capabilities, effectively penetrating the concrete surface and actively undergoing continuous chemical reactions with the concrete. The effective components of lithium-based sealant curing agents combine with free calcium, potassium, and other ions that can reduce concrete strength to form a non-expanding, non-shrinking, stable chemical copolymer—hydrated calcium silicate—that fills the capillaries in the concrete. This makes the entire concrete a dense, solid, dust-free, crack-free, breathable, and colorful whole, achieving hardening, strengthening, dust prevention, waterproofing, weather resistance, wear resistance, alkali 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 pressure resistance. Concrete sealant curing agent application range: It requires a clean environment and has certain requirements for the dust content in the air, but it is 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 flat new and old concrete surfaces. For example: factory, warehouse, freight distribution area, shopping center, parking lot, service station, hangar, and other floor areas.
