The company specializes in custom MS polymer sealants, offering tailored formulations to meet specific client requirements, from viscosity and curing time to color and adhesion properties.
MS Polymer Technology: A Green Revolution
MS polymer (Modified Silane Polymer) technology is at the heart of CHEMPU’s product lineup. Unlike traditional polyurethane or silicone sealants, MS polymers combine the best attributes of both—high elasticity, strong adhesion, and excellent weather resistance—while being solvent-free and low in volatile organic compounds (VOCs). CHEMPU’s advanced MS polymer series, including the eco-friendly 2026 lineup, is designed to meet stringent health and environmental standards. These sealants are ideal for indoor applications where paintability and low odor are critical. The company’s R&D efforts have led to ‘primer-less’ technology, which allows the sealant to bond directly to most substrates without the need for a separate primer. This reduces labor costs and application time, making CHEMPU’s custom MS polymer sealants a favorite among construction professionals.
Product Portfolio
CHEMPU offers a comprehensive range of professional-grade chemical bonding solutions. Key product categories include:
- Structural PU Sealants (PU-30/40): Engineered for heavy-duty construction joints, these sealants provide exceptional elasticity and D4-level water resistance.
- Advanced MS Polymer Series (MS-30/50/828): The 2026 eco-friendly lineup is solvent-free and zero-VOC. MS-828 is perfect for indoor flooring, while MS-50 excels in industrial structural bonding where paintability and health standards are paramount.
- Automotive Glass Adhesives (PA Series): The PA-1601F series supports a 1-hour Safe Drive-Away Time (SDAT), meeting OEM standards. The PA-145N odorless series is preferred for high-speed rail and subway interiors.
- Specialty Self-Leveling Adhesives: Designed for horizontal joints in warehouses and workshops, ensuring a seamless, durable finish.
All products are tested to meet ASTM C639 and ASTM C1183 standards, providing high mechanical strength and excellent aging resistance. CHEMPU’s custom MS polymer sealants can be formulated to meet specific customer needs, including variations in color, consistency, and curing speed.
