Premium Polyurethane Pavement Sealer for Sealant Concrete Expansion Joints Caulking

Dec 16,2025

PU 11FC is a cold applied, high performance, hydrocabon resistant premium polyurethane pavement sealer for sealant concrete expansion joints caulking np1. Sealant for cracks in concrete key advantages include excellent adhesion to various substrates, high tear strength (7 N/mm), and outstanding sag resistance (0 mm), enabling clean vertical and overhead application. With a displacement capacity of ±20% and elongation at break exceeding 400%, it effectively accommodates structural movement and thermal expansion in joints, a critical requirement in dynamic building envelopes.

This concrete paver sealant addresses common construction pain points by offering robust performance in diverse environments (service temperature range from -40°C to +80°C) and strong resistance to water, weathering, and weak alkalis. Its well-defined technical guidelines—such as joint design (width-to-depth ratio ~1:0.8), surface preparation, and the use of recommended primers—ensure reliable long-term sealing and reduce application errors. Additionally, PU fc11 cures reliably under ambient moisture, with a cure rate >3 mm/24h, supporting efficient project timelines.

While not suitable for continuous water immersion, PU 11 fc provides a durable, flexible, and high-strength sealing solution for manufacturing plant for water proof sealant for flat concrete roofs, joint sealant for wall concrete, road-specific joint sealant and special sealant for road, making it a versatile choice for both interior caulking and sealant outdoor.
