CS-250 High Tack, Butyl Rubber Sealant

SEALING PROPERTIES

• Provides permanently pliable watertight joints.
• Low to high temperature workability: 30°F to 120°F (-1°C to +49°C)
• Rugged service temperature: -30°F to +200°F (-34°C to +93°C)
• Excellent chemical and mechanical adhesion to clean dry surfaces.
• Greater cohesive and adhesive strengths.
• Sealed joints will not shrink, harden or oxidize upon aging.
• Controlled flow resistance for application ease.
• ConSeal CS-250 meets or exceeds all of the requirements of ASTM C990.
• No priming normally necessary. When confronted with difficult installation conditions, such as wet concrete or temperatures below 40°F (4°C), priming the concrete will improve the bonding action. Consult Concrete Sealants for the proper primer to meet your application.
