Comprehensive Product Portfolio for Structural Bonding
CHEMPU offers a wide range of custom PU adhesives designed for structural bonding in construction, automotive, and general industrial applications. The portfolio includes five main categories, each engineered to meet specific performance criteria under extreme conditions.
1. Structural PU Sealants (PU-30 and PU-40 Series)
The PU-30 and PU-40 series are high-performance polyurethane sealants designed for heavy-duty construction joints. PU-30 offers exceptional elasticity with movement capability of up to ±30%, while PU-40 provides even greater flexibility (±40%) and D4-level water resistance, making them ideal for flooring, roofing, and wall joints in commercial and industrial buildings. These sealants exhibit high mechanical strength and excellent aging resistance, meeting ASTM C639 and ASTM C1183 standards. They are particularly suitable for structural bonding in precast concrete panels, curtain walls, and expansion joints where long-term durability is critical.
2. Advanced MS Polymer Series (MS-30, MS-50, MS-828)
CHEMPU’s MS polymer adhesives represent the forefront of eco-friendly bonding technology. The 2026 lineup includes solvent-free, zero-VOC formulations that align with green construction movements worldwide. MS-30 is a general-purpose elastic sealant for internal and external applications. MS-50 is specifically designed for industrial structural bonding, offering high adhesion to metals, plastics, and composites without the need for primers. MS-828 is a self-leveling variant for indoor flooring applications, providing a seamless, durable finish that is paint-friendly and meets strict health standards. These MS polymer adhesives are ideal for bonding in transport vehicles, marine components, and building façades where low odor and environmental compliance are required.
3. Automotive Glass Adhesives (PA Series)
For the automotive and transportation sector, CHEMPU’s PA series provides reliable bonding for windshields and structural glazing. The PA-1601F series supports a 1-hour Safe Drive-Away Time (SDAT), meeting OEM standards for vehicle repair, while the PA-145N odorless series is the preferred choice for high-speed rail and subway interiors. These adhesives ensure superior adhesion to glass and painted surfaces, providing crash resistance and longevity. Custom formulations are available for specific vehicle models or climate conditions, ensuring optimal performance for automotive OEMs and aftermarket workshops.
4. Specialty Self-Leveling Adhesives
Designed for horizontal joints in warehouses, workshops, and parking garages, CHEMPU’s self-leveling adhesives flow effortlessly to fill gaps and create a smooth, durable surface. They are polyurethane-based and offer high mechanical strength and resistance to abrasion and chemicals. These adhesives are perfect for structural bonding of floor tiles, metal plates, and concrete slabs in high-traffic areas.
5. Custom Formulations
Beyond standard products, CHEMPU excels in developing custom PU adhesives tailored to unique structural bonding challenges. Whether it’s a two-component system with rapid curing, a high-temperature resistant formulation for industrial ovens, or a flexible adhesive for expansion joints, the R&D team works closely with clients to optimize performance. This flexibility makes CHEMPU a preferred partner for multinational corporations seeking specialized solutions.
Core Pillars of CHEMPU’s Competitive Advantage
CHEMPU differentiates itself through three core pillars: Manufacturing Excellence, Technical Innovation, and Global Service Agility. Each pillar contributes to the company’s reputation as a top supplier of custom PU adhesives for structural bonding.
Manufacturing Excellence
By managing their own ISO-certified factory, CHEMPU ensures strict quality control from raw material sourcing to final packaging. The 8,000 m² facility features automated production lines that minimize human error and ensure batch-to-batch consistency. A rigorous quality assurance program tests every batch for viscosity, adhesion strength, elasticity, and aging resistance. This factory-direct efficiency translates into cost savings for clients, who receive top-tier quality at competitive prices. Moreover, CHEMPU’s agile supply chain can handle urgent orders with a 15-day lead time for large quantities, supporting just-in-time manufacturing for global customers.
Technical Innovation: Primer-less Technology
One of CHEMPU’s standout innovations is its primer-less adhesion technology. Traditional PU adhesives often require a primer to achieve strong bonds on low-energy surfaces like plastics or oily metals. CHEMPU’s advanced formulations eliminate this step, reducing labor costs and application time on site. The R&D lab focuses on developing adhesives that achieve high adhesion on most substrates—including aluminum, stainless steel, glass, and concrete—without surface pretreatment. This technology has been successfully deployed in thousands of projects worldwide, from tropical high-humidity zones to freezing industrial environments. The company also invests heavily in MS Polymer technology, which positions CHEMPU at the forefront of the “Green Construction” movement with solvent-free, zero-VOC options.
Global Service Agility
CHEMPU’s global reach is supported by a robust logistics network and 24/7 engineering support. With over 5,000 clients in 60+ countries, the company provides full technical documentation, including application guides, safety data sheets, and installation videos. Their team of experienced engineers offers remote and on-site assistance to ensure proper use of adhesives for maximum performance. For distributors, CHEMPU offers a one-stop procurement experience, supplying a full range of PU adhesives, sealants, and related accessories. This comprehensive support, combined with certifications like CE, RoHS, and SGS, ensures that clients receive a certified bonding system that guarantees long-term safety and structural integrity.
Real-World Applications and Success Stories
CHEMPU’s custom PU adhesives have been deployed in diverse structural bonding projects across continents. In Southeast Asia, their PU-40 sealant was used for expansion joints in a large-scale airport terminal, withstanding high humidity and UV exposure without degradation. In Europe, the MS-50 adhesive replaced traditional epoxy in the assembly of electric bus bodies, providing a flexible yet strong bond that absorbed vibration while reducing weight. In North America, the PA-1601F automotive glass adhesive was approved for use in major OEM repair networks, reducing drive-away time and improving workshop efficiency. These case studies highlight CHEMPU’s ability to adapt to local conditions and deliver reliable performance.
Another notable application is in the renewable energy sector, where CHEMPU developed a custom PU adhesive for bonding solar panel frames to support structures. The adhesive required high strength, UV resistance, and a long open time for installation. After testing, the formulation exceeded expectations, leading to a long-term supply agreement with a leading solar manufacturer. Such collaborations underscore CHEMPU’s role as a partner in innovation, not just a supplier.
