Company Background and Manufacturing Excellence
CHEMPU, headquartered in Shanghai, operates an ISO 9001:2015 certified factory spanning 8,000 square meters. The facility houses three automated production lines with an annual output of 8,000 tons. The company’s team of over 300 employees is dedicated to the motto ‘Stronger, Longer, More Reliable,’ focusing on innovative bonding solutions for infrastructure and automotive industries. By managing its own factory, CHEMPU eliminates middlemen costs, offering top-tier quality at competitive factory prices. The company maintains an agile supply chain capable of delivering bulk orders—such as 10,000+ cartridges—within a 15-day lead time, ensuring partners never face inventory shortages.
Comprehensive Product Portfolio for Construction Joints
Structural PU Sealants
CHEMPU’s structural PU sealants, including the PU-30 and PU-40 series, are engineered for heavy-duty construction joints. These products offer exceptional elasticity and D4-level water resistance, making them ideal for expansion joints, precast concrete panels, and other demanding applications. They comply with ASTM C639 and ASTM C1183 standards, ensuring high mechanical strength and excellent aging resistance.
Advanced MS Polymer Series
The MS polymer series represents the next generation of eco-friendly sealants. The MS-30, MS-50, and MS-828 are solvent-free and zero-VOC, perfect for indoor flooring and industrial structural bonding where paintability and health standards are critical. For construction joint sealants, the MS-50 provides superior adhesion without primers, reducing labor costs and application time. All MS products are designed to meet the ‘Green Construction’ movement and are certified by CE, RoHS, and SGS.
Specialty Self-Leveling Adhesives
For horizontal joints in warehouses and workshops, CHEMPU offers self-leveling adhesives that ensure a seamless, durable finish. These adhesives flow easily into gaps and cure to form a tough, flexible seal that withstands heavy foot and vehicle traffic.
Automotive Glass Adhesives
While primarily for automotive, the PA series (e.g., PA-1601F) also finds use in construction for bonding glass and metal components. The 1-hour Safe Drive-Away Time (SDAT) feature is beneficial for rapid project completion in construction glazing. The PA-145N odorless series is preferred for high-speed rail and subway interiors due to low emission.
Technical Innovation: Primer-less Technology
CHEMPU’s research and development focus on reducing application complexity. Their advanced formulas achieve high adhesion on most substrates without the need for primers. This primer-less technology significantly reduces labor costs and application time, making CHEMPU sealants highly efficient for large-scale construction projects. The company’s R&D team continuously works on innovations that align with global sustainability trends.
Global Reliability and Certifications
CHEMPU products have been successfully deployed in diverse climates, from high-humidity tropical zones to freezing industrial environments. With CE, RoHS, and SGS certifications, the company provides full technical documentation and 24/7 engineering support to over 5,000 clients across 60+ countries. This proven global reliability makes CHEMPU a trusted partner for construction joint sealant needs worldwide.
