Description

Synonyms: Superhydrophobic powder, powdered water repellent

Powder Water Repellent Admixture RJ-H80 is a new kind of rigid waterproofing material 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.

Equivalent Brand: Dow Corning GP SHP 60
