Structural PU Sealants (PU-30/40)

These sealants are designed for heavy-duty construction joints, offering exceptional elasticity and D4-level water resistance. Ideal for expansion joints in bridges, tunnels, and industrial floors, they provide long-term durability under dynamic stress.

Advanced MS Polymer Series (MS-30/50/828)

The 2026 eco-friendly lineup is solvent-free and zero-VOC, perfect for indoor applications. MS-828 is specifically formulated for indoor flooring, ensuring paintability and compliance with health standards. MS-50 is used for industrial structural bonding where high mechanical strength is required. These MS polymer sealants offer excellent adhesion to a variety of substrates without the need for primers, thanks to CHEMPU’s innovative primer-less technology.

Automotive Glass Adhesives (PA Series)

The PA-1601F series supports a 1-hour Safe Drive-Away Time (SDAT), meeting OEM standards for vehicle repair. The PA-145N odorless series is the preferred choice for high-speed rail and subway interiors, providing a comfortable environment without harmful fumes.

Specialty Self-Leveling Adhesives

Designed for horizontal joints in warehouses and workshops, these adhesives ensure a seamless, durable finish. They are perfect for large-scale industrial floors where efficiency and reliability are critical.

Manufacturing Excellence: Factory-Direct Efficiency

One of CHEMPU’s core differentiators is its factory-direct model. By owning and operating its ISO 9001:2015 certified facility, the company eliminates middlemen costs, offering top-tier quality at competitive factory prices. The supply chain is agile enough to deliver bulk orders (e.g., 10,000+ cartridges) within a 15-day lead time, ensuring partners never face inventory shortages. This efficiency is backed by a professional team that monitors every production stage, from raw material selection to final packaging.

Automated Production Lines

The 8,000 m² factory houses three fully automated lines, each capable of producing different product types simultaneously. This flexibility allows CHEMPU to respond quickly to market demands, whether for high-volume standard sealants or customized formulations for specific projects.

Technical Innovation: R&D-Driven Primer-less Technology

CHEMPU’s lab focuses on reducing application complexity. The company’s advanced formulas achieve high adhesion on most substrates without the need for primers, significantly reducing labor costs and application time for construction teams. This primer-less technology is especially beneficial for MS polymer sealants, which are often used in environments where surface preparation is challenging. The R&D team continuously tests new polymers and additives to enhance weather resistance, elasticity, and UV stability.

Green Construction Movement

With global emphasis on sustainability, CHEMPU’s MS polymer series aligns perfectly with the “Green Construction” movement. The solvent-free, zero-VOC formulations contribute to better indoor air quality and reduced environmental impact. These sealants are also free from isocyanates, making them safer for applicators. By choosing CHEMPU, contractors can meet green building certifications like LEED and BREEAM.

Global Reliability: Proven in Diverse Climates

CHEMPU’s products have been successfully deployed in diverse climates, from high-humidity tropical zones to freezing industrial environments. The sealants maintain their performance across a wide temperature range (-40°C to 80°C) and resist cracking, shrinking, and aging. This reliability is a result of rigorous testing against ASTM C639 (for sealant behavior under cyclic movement) and ASTM C1183 (for adhesion and cohesion).

Client Testimonials and Case Studies

Over 5,000 clients across 60+ countries rely on CHEMPU for their bonding needs. For example, a major infrastructure project in Southeast Asia used MS-50 for structural bonding of steel panels, withstanding high humidity and salt spray. In Europe, the PA-145N odorless adhesive was chosen for subway car assembly, ensuring passenger comfort. These real-world applications demonstrate the brand’s consistency and trustworthiness.

One-Stop Procurement and Technical Support

CHEMPU provides more than just products. The company offers full technical documentation, material safety data sheets, and 24/7 engineering support. Distributors benefit from marketing materials, samples, and training programs. The one-stop procurement model simplifies logistics—clients can order multiple product categories (PU sealants, MS polymer, automotive adhesives) from a single source, saving time and reducing administrative costs.
