Description

Synonyms: Superhydrophobic powder, waterproof powder 

Powder Water Repellent RJ-H80 is a new kind of superhydrophobic powder for building with good permeability and crystallinity. Crosslinking reaction happens between Si-OH in the molecular structure and Si-OH in silicate materials under the condition of moisture. So-called “anti-capillary effect” occurs to form an excellent waterpoofing layer.At the same time, it will have the effect of microdilatancy and will increase the compressive strength of the concrete.
