TEGOSIVIN HE 328

TEGOSIVIN HE 328 is a solvent-free emulsion based on reactive organo-modified siloxanes and silanes. It provides effective protection against water and reduces primary and secondary efflorescence of building materials. TEGOSIVIN HE 328 reduces corrosion of steel reinforced concrete and provides a non-tacky finish with stain release effect. It has alkali resistance and reduces heat conductivity, thus improving thermal insulation. TEGOSIVIN HE 328 does not reduce water vapour permeability and in most cases does not change the surface appearance. As an admixture or surface treatment, TEGOSIVIN HE 328 durably protects from water-induced damages. It can be added to cement based formulations or used for pre-treatment and injected DPC applications. TEGOSIVIN HE 328 treated materials have performance advantages in various construction related applications.
