Explore our specialized waterproof adhesive sealant portfolio tailored for harsh environmental protection, rigorous dielectric requirements, and extreme dynamic stresses across US industries.
From the gigafactories of Michigan and Texas to the aerospace clusters of California and Washington, the United States is driving unparalleled demand for next-generation waterproof adhesive sealants that withstand dynamic thermal swings, chemical corrosion, and intense mechanical vibration.
The acceleration of electric vehicle (EV) production across North America requires battery pack sealants that provide dual-barrier protection: IP68 moisture hermeticity preventing thermal runaway from water ingress and high-dielectric breakdown strength safeguarding high-voltage busbars.
US defense contractors and commercial aviation innovators demand silver-filled and nickel-plated conductive sealants achieving >60dB EMI shielding while preventing salt-fog moisture degradation in airborne phased array radars and avionics pod assemblies.
Outdoor 5G massive MIMO towers and utility-scale solar micro-inverters across diverse US climates require elastomeric silicones and PUR formulations capable of surviving -45°C Alaskan winters, 50°C Arizona heat waves, and intense UV degradation for 20+ years.
In modern US manufacturing, adhesive selection goes beyond basic bonding metrics. Industrial engineers require material solutions that fully comply with US environmental and safety frameworks, including EPA TSCA inventory validation, California Proposition 65 limits, low VOC standards, and rigorous UL 94 V-0 flame-retardant certifications.
Songxi Technology integrates cutting-edge polymer synthesis with automated rheological testing to supply US OEMs with sealants that optimize automated dispensing cycles, deliver primer-free adhesion on engineering thermoplastics (PBT, PPS, Polycarbonate), and maintain bond line integrity under severe cyclic mechanical shock.
Songxi Technology is a premier high-tech enterprise specializing in the R&D, production, and worldwide sales of advanced electronic adhesives and functional sealants. Based on silicone, polyurethane, acrylic, and epoxy systems, we provide reliable bonding, sealing, and protection solutions for power electronics, optoelectronics, new energy, automotive, and aerospace industries.
We are committed to becoming a trusted provider of functional polymer material solutions for the electronics industry. Through continuous innovation and application development, we promote the localization of high-end electronic adhesives and help intelligent devices achieve greater stability, longevity, and durability across demanding global markets.
Songxi's business covers three functional areas: adhesive & sealing, potting & protection, and thermal interface materials. Our product portfolio includes PCBA fixing adhesives, UV adhesives, sealants, thermal conductive potting compounds, thermal greases, pads, two-component thermal gels, EMI shielding sealants, and reactive hot melt adhesives.
Addressing the complex engineering challenges faced by American Tier-1 suppliers and equipment manufacturers through agile R&D and bespoke formulation modifications.
Our products serve power batteries, photovoltaic modules, drones, automotive electronics, 5G communications, and LED lighting. We provide both standard products and customized solutions for applications such as BMS conformal coating, IGBT thermal filling, and power battery structural bonding, supported by extensive technical experience and application expertise.
With high-density component packing on modern PCBAs, moisture combined with bias voltages induces catastrophic dendritic short circuits. Songxi’s specialized component fixing adhesives feature exceptional dielectric strength and ultra-pure matrix chemistry, physically blocking moisture paths and neutralizing ionic migration on surface-mount devices.
To support high-speed automated manufacturing lines in North American facilities, our reactive Polyurethane Hot Melt (PUR) and Dual-Cure (UV + Moisture) structural adhesives deliver rapid green strength within seconds and full deep-section cross-linking, passing stringent 1.5m drop testing and automotive salt-spray trials.
Led by a Ph.D. in Polymer Materials from Sichuan University, Songxi's R&D team has nearly twenty years of silicone application experience and has participated in over 100 product development projects. We maintain cooperation with research institutions including Chenguang Chemical Research Institute, Sichuan University, and Beijing Institute of Technology.
Certified with ISO9001, Songxi operates a comprehensive management system covering procurement, production, inspection, and after-sales service. Our products comply with RoHS and REACH requirements, with SGS verification and UL 94 V-0 flame retardant certification, ensuring consistent quality, reliable delivery, and peace of mind for critical engineering projects.
Our testing labs simulate extreme environmental stresses including 85°C / 85% RH damp heat aging, -55°C to 150°C thermal shock cycles, dielectric breakdown voltage analysis, and multi-axis vibrational resonance testing to ensure our waterproof sealants exceed American industry benchmarks (ASTM D1002, ASTM D412, IPC-CC-830).
