WATER-REPELLENT LIGHT WEIGHT CELLULAR CONCRETE PANEL, METHOD OF PRODUCING THE AFORESAID, AND WATER-BASED ORGANOPOLYSILOXANE EMULSION

摘要

A water-repellent lightweight cellular concrete panel having on its surface a water-repellent treatment layer provided by a water-based emulsion of a non-film-forming amino-modified organopolysiloxane. A water-based emulsion of a non-film-forming amino-modified organopolysiloxane is applied, by a spray method or a roller coating method, on the surface of lightweight cellular concrete panel and drying is carried out. An O/W water-based emulsion of a non-film-forming amino-modified organopolysiloxane that has an amine equivalent weight of 500 to 100,000 gram/mol and a viscosity at 25 °C of 50 to 1,000,000 mPa·s.
