WATER REPELLENTS: SW-244 Siloxane Penetrating Water Repellent

Product Data Sheet    Material Safety Data Sheet    Architectural Specification

PRODUCT DESCRIPTION

SW-244 is a  D.O.T. approved concrete protective treatment.  It is not a surface coating. SW-244 penetrates up to 1/4 inch or more into treated surfaces and bonds with the substrate to provide long lasting, hydrophobic protection, even at hairline cracks. SW-244 was designed for the protection of concrete structures such as roads, bridges, parking decks and many other horizontal and vertical structures. SW-244 meets or exceeds the protection requirements detailed in the NCHRP 244 Report.

SW-244 consists of 100% active ingredients that physically and chemically react with the substrate. This forms a photo-reactive surface which becomes water repellent after just 4 to 24 hours of exposure to ultra-violet light (direct or indirect sunlight) and continues to increase in effectiveness through several weeks of exposure.

• Solids content by weight: 16%
