FAQs of Polysulphide Sealant:

Q: How should Polysulphide Sealant be applied in construction projects?

A: Polysulphide Sealant should be applied using a spatula or caulking gun. The surface must be clean and dry before application to ensure proper adhesion and optimal sealing performance.

Q: What benefits does the high elongation at break offer to users?

A: With an elongation at break greater than 300%, this sealant accommodates significant structural movement, preventing cracks and leaks even under dynamic loading conditions.

Q: When is the sealant fully cured and ready for service exposure?

A: The sealant achieves full cure within 24-48 hours, depending on ambient temperature and humidity levels. Once cured, it withstands a service temperature range between -25C and +80C.

Q: Where is Polysulphide Sealant most commonly used in India?

A: It is widely used in industrial and construction sectors throughout India, especially for joints and gaps requiring durable, chemical-resistant sealing in structures, tanks, pipelines, and concrete surfaces.

Q: What is the recommended process for achieving optimal results?

A: For best results, apply the sealant within its 60-90 minute pot life and ensure a skin formation time of 2-4 hours. Regular inspections during application aid in achieving consistent coverage and bonding.

Q: How does its chemical composition enhance performance in challenging environments?

A: Featuring a blend of polysulfide polymers, the sealant resists the detrimental effects of fuels, oils, and solvents, making it suitable for demanding industrial and construction applications.

Q: What are the key usage and environmental benefits of this sealant?

A: Its low VOC content and high purity contribute to a safer workspace and minimal environmental impact, ensuring compliance with current industry standards for sustainable operations.
