Adhesive Solution for String Inverters: One-stop Package for Thermal Conduction, Potting, Conformal Coating & Sealing

In photovoltaic energy storage systems, string inverters serve as core equipment responsible for DC-AC conversion, power regulation, grid-tied control and system protection. As PV inverters evolve toward higher power density, long-term outdoor operation, superior reliability and automated manufacturing, stricter standards are imposed on adhesive materials for internal power components, PCBs, inductors, connectors, capacitors, heat dissipation structures and enclosure sealing. If you are searching for inverter potting compound, inductor potting adhesive, connector encapsulant, PV inverter thermal interface materials, PCB conformal coating or inverter enclosure sealant, Elaplus Functional Materials (Shanghai) Co., Ltd. delivers a full one-stop adhesive solution covering thermal transfer, potting, three-proof protection, structural bonding and sealing. Our products are applicable to string inverters, PV inverters, energy storage inverters and other new energy power electronic devices. I. Why Do String Inverters Require Specialized Adhesives? String inverters run continuously on rooftop PV stations, industrial & commercial PV projects, ground-mounted power plants and PV energy storage systems amid harsh operating conditions, including rapid high-low temperature cycling, heat & humidity, salt spray, dust, rainwater, UV aging, mechanical vibration and sustained heat generation from power components. In such working environments, adhesives do not merely fix parts in place; they fulfill these critical core functions: ■ Thermal Conduction & Heat Dissipation: Reduce interfacial thermal resistance between power semiconductors, power modules and heat sinks. ■ Potting Protection: Provide insulation, moisture resistance and shock resistance for critical parts such as connectors, inductors and capacitors. ■ PCB Three-proof Coating: Boost circuit board resistance to moisture, corrosion, salt spray and enhance electrical insulation. ■ Component Fixation: Prevent loosening, cracking and fatigue failure caused by vibration and impact. ■ Enclosure Sealing: Elevate overall waterproof, dustproof and outdoor weather resistance of the inverter. Therefore, PV inverter manufacturers, energy storage inverter producers and new energy power equipment makers directly determine equipment reliability and service life by selecting proper…

Elaplus sharing Case of PCB Encapsulation Inside Wiring Harness

BackgroundIn modern electronic devices, wire harnesses serve as important bridges connecting various electronic components, and their stability and reliability are crucial. The internal wiring harness usually includes multiple wires and related connectors, circuit boards (PCBs) and other sensitive components, which are subjected to various adverse effects from the external environment, such as moisture, dust, vibration, temperature fluctuations, etc. In order to ensure the long-term stable operation of the equipment and protect these internal components from external interference, encapsulation technology has become a crucial solutionAmong them, PCB (Printed Circuit Board) is the core part of electronic devices, which not only undertakes signal transmission and processing functions, but also directly affects the stability of the entire system. In order to effectively prevent PCB from being damaged by environmental factors such as moisture, chemicals, and corrosive gases, protective measures must be taken. Traditional protection methods often rely on coatings or packaging, but these methods often cannot achieve ideal protection effects, especially in high humidity, high temperature, and frequent vibration environments. Therefore, choosing an efficient and deep curing potting material has become the key to ensuring the long-term stable operation of PCBs.Solution:In response to this challenge, Yilian’s PUR 1680 two-component solvent-free room temperature or heat cured resin elastomer composite provides us with an ideal solution. This material is specifically designed for two-component sealing and potting of electrical equipment. It not only has excellent physical properties, but also ensures the long-term reliability of wiring harnesses and PCBs in complex environments. Characteristics of PCB encapsulation products inside wire harnesses▶ High thermal conductivity, low viscosity, strong operability▶ Excellent low-temperature characteristics and outstanding weather resistance▶ Excellent electrical insulation and stability stability▶ Good waterproof and moisture-proof properties, with extremely low water absorption rate▶ Has good adhesion to most metals and plasticsApplication scenarios:PUR 1680 is an ideal choice for sealing…
