Three real application cases of insulating colorants: epoxy powder coating of switchgear busbars (42 kV/1 min, GB/T 11022), epoxy potting of IGBT modules (23 kV/mm, 3.4×10¹⁵ Ω·cm), and silicone potting of 120 kW charging modules (1.0 W/m·K, UL 94 V-0, IP65), with process data and selection parameters....

Insulating colorants explained: dielectric mechanism and the three key parameters—volume resistivity (≥1×10¹⁴ Ω·cm, GB/T 1410), dielectric strength (≥20 kV/mm, GB/T 1408), and loss tangent (≤0.020, GB/T 1409)—with VPI, epoxy casting, and PCB potting case data and selection guidance....

1. IntroductionStructural adhesive bonding is replacing bolts, rivets, and spot welds across automotive, appliance, and equipment manufacturing because multi-material lightweighting and electrification favor continuous, sealing, stress-distributing joints. The decision, however, should be made on to...

1. IntroductionCyanoacrylate (CA) instant adhesives are one-part, fast-curing adhesives that fixture in seconds using only trace surface moisture, and they dominate high-speed assembly of electronics, rubber seals, plastics, and medical devices. Their main drawbacks are cure blooming (white frost),...

1. IntroductionEpoxy structural adhesives are the primary load-bearing joining material in modern wind turbine rotor blades, bonding the two composite half-shells, the shear webs, and the spar caps into a single fatigue-resistant structure. As offshore blades exceed 100-115 m in length, bond-line in...

1. IntroductionAnaerobic threadlockers are single-component acrylic adhesives that cure in the absence of air when confined between close-fitting metal surfaces, and they are the most widely used engineering solution for preventing self-loosening of threaded fasteners under vibration. This article e...

1. IntroductionBio-based adhesives and debondable (on-demand removable) adhesives are the two fastest-growing segments of the sustainable adhesives market, driven by extended-producer-responsibility regulation, EV battery-recycling mandates, and corporate carbon-reduction targets. This article defin...

1. IntroductionThermally conductive adhesives combine structural bonding with thermal interface material (TIM) functions in a single bond line, and they have become standard in electric-vehicle (EV) power electronics, where junction temperatures of silicon-carbide (SiC) devices can exceed 150 deg C...

1. IntroductionSilane-modified polymer adhesives (SMP, also called MS polymer adhesives) are moisture-curing elastic adhesives based on silyl-terminated polyether (STPE) resins. They combine the toughness of polyurethane adhesives with the weathering resistance of silicones, while being isocyanate-f...

[Introduction]Driven by global carbon-neutral goals and tightening environmental regulations, the adhesive industry is undergoing a profound shift from solvent-borne to waterborne, solvent-free, and UV-cured low-carbon technologies. According to Nature Sustainability and ACS Sustainable Chemistry an...
