Sure Klean® Weather Seal Siloxane PD (predilute) <br />is a ready-to-use, water-based silane/siloxane water <br />repellent for concrete and most masonry and stucco <br />surfaces. Siloxane PD will not impair the natural <br />breathing characteristics of treated surfaces. It <br />helps masonry resist cracking, spalling, staining <br />and other damage related to water intrusion. Low <br />odor and alkaline stable, Siloxane PD is ideal for <br />field and in-plant application. <br />TYPICAL TECHNICAL DATA <br />FORM Cloudy white liquid, odorless <br />SPECIFIC GRAVITY 0.996 <br />pH 4–5 <br />WT/GAL 8.29 lbs <br />ACTIVE CONTENT 7% <br />TOTAL SOLIDS 4% ASTM D 5095 <br />VOC CONTENT <30 g/L Low Solids Coating <br />FLASH POINT >212° F (>100° C) ASTM D 3278 <br />FREEZE POINT 32° F (0° C) <br />SHELF LIFE 1 year in tightly sealed, unopened container <br />ADVANTAGES <br />• Penetrates deeply for long-lasting protection on <br />vertical or horizontal surfaces. <br />• Service life is estimated at more than 10 years. <br />• Treated surfaces “breathe” – does not trap moisture. <br />• Water-based formula minimizes explosion and <br />fire hazards compared to solvent-based water <br />repellents. <br />• Appropriate for use on manufactured stone surfaces. <br />• Resists water penetration when applied over <br />existing shrinkage cracks of 0.02 inches or less. <br />• Easy cleanup with PROSOCO’s 2010 All Surface <br />Cleaner. <br />• Low odor for safer application to occupied buildings. <br />• Alkaline stable – suitable for new “green” <br />concrete, 14–28 days old. <br />• Ready-to-use. No on-site dilution required. <br />Limitations <br />• Will not keep water out of cracks, defects or open <br />joints. <br />• Not appropriate for use on limestone, marble, <br />travertine or other calcareous stones. Always test <br />other natural stone to ensure desired results. <br />• Not recommended for below-grade application. <br />• Not suitable for application to synthetic resin <br />paints, gypsum, or other non masonry surfaces. <br />REGULATORY COMPLIANCE <br />VOC Compliance <br />Sure Klean® Weather Seal Siloxane PD is compliant <br />with the US Environmental Protection Agency’s <br />AIM VOC regulations.
