赛纳涂® D200 纳米二氧化硅混凝土养护固化剂

1产品简介/Product Overview

赛纳涂® D200 为纳米二氧化硅水性养护固化剂，专为新浇筑混凝土、水泥砂浆、无机磨石研发。经1 : 4兑水稀释后低压喷涂于基面，可快速在表层形成致密密闭保湿保护膜，牢牢锁住基材内部游离水分、大幅降低水分蒸发，实现免洒水、免覆盖自然养护。CERGURD® D200 is a colloidal silica curing agent developed for fresh concrete, cement mortar, inorganic terrazzo. After dilution with water at 1 : 4 and low-pressure spray application, it quickly forms a dense closed moisturising protective film on the surface, effectively locking in free moisture within the substrate and significantly reducing water evaporation — achieving natural curing without water spraying or covering.
