CS-202 Butyl Rubber Sealant

SEALING PROPERTIES

• Provides permanently pliable watertight joints.
• Low to high temperature workability: 0°F to 120°F (-18°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-202 meets or exceeds all of the requirements of Federal Specification SS-S-210 (210-A), AASHTO M-198B, and 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.

HYDROSTATIC STRENGTH

ConSeal CS-202 meets the hydrostatic performance requirement as set forth in ASTM C990 section 10.1 (Performance requirement: 10psi for 10 minutes in straight alignment – in plant, quality control test for joint materials.)

SPECIFICATIONS

ConSeal CS-202 meets or exceeds all of the requirements of Federal Specification SS-S-210 (210-A), AASHTO M198B, and ASTM C990-91.
