Experiment § Development of Cryogenic Filament Winding Epoxy Resin Systems With the rapid growth of cryogenic applications such as liquefied natural gas (LNG), liquid oxygen, and aerospace, composite materials are required not only to provide a high strength-to-weight ratio but also to maintain excellent toughness and structural stability under cryogenic conditions. To meet the requirements of the filament winding (FW) process, our company has developed three cryogenic epoxy

Experiment § Motors Magnet Bonding Adhesive In electric vehicle motors, new energy vehicle drive systems, industrial motors, and precision electronic assemblies, the magnets (such as NdFeB and ferrite)on the rotor and stator must be securely bonded to metal substrates (Fig. 1). Insufficient bond strength may cause the magnets to loosen after prolonged exposure to high temperatures and vibrations, which can compromise motor performance. To address this issue, Everwide has deve

Experiment § FX208-17 Solvent-Based Silicone Conformal Coating Modern electronic systems such as electric vehicles, aircraft, and outdoor precision instruments rely on printed circuit boards (PCBs) as their core control units. When exposed to moisture, extreme temperature variations, or vibration, PCBs are susceptible to short circuits and failure. Silicone conformal coating functions as an invisible protective layer that safeguards these critical components. Silicone materia

Experiment § GF256 Acrylic Hydrophilic Coating Film During heavy rain, whether driving a car or riding a motorcycle, water droplets adhering to frequently rain-exposed surfaces such as windshields, side mirrors, and helmet visors can easily cause blurred vision and affect driving safety. To address this issue, we have developed GF256 Acrylic Hydrophilic Coating Film (Figures 1 and 2). Unlike conventional anti-fog hydrophilic coatings, GF256 can rapidly spread water droplets a

Experiment § Epoxy Cationic Balancing Adhesives In recent years, electronic products have continued to develop toward higher reliability and miniaturization, leading to increasing demand for balancing adhesives. These adhesives are widely used in cooling fans, motor rotors, and precision rotating components (Fig. 1). Their primary function is to correct weight deviation, reduce vibration and noise during operation, and improve overall stability and service life. In response t

Experiment § Development of Phenoxy Resin Phenoxy resin is a high-performance thermoplastic amorphous polymer with excellent compatibility. It can be widely used in polyurethane, polyester, and epoxy resin systems as a resin modifier (Figure 1). The addition of phenoxy resin effectively improves material toughness and chemical resistance, while significantly reducing resin loss in composites.Its molecular structure contains abundant hydroxyl functional groups, enabling reacti

Experiment § Solutions for Preventing Cracking in High-Hardness Lens Coatings In high-hardness lens coating applications, coatings are required not only to maintain excellent optical transparency, but also to provide abrasion resistance, adhesion, and long-term stability. When only a single coating layer is applied, the high hardness of the material can easily lead to cracking or delamination during environmental reliability testing. To address this issue, a primer layer is f

Experiment § Improvement of Crystallization Issues in Solvent-Based Resins During storage of epoxy resin products, crystallization of liquid resins is often observed. This not only affects appearance but also reduces usage stability (Fig. 1). The occurrence of crystallization is related to factors such as purity, chlorine content, molecular weight, and temperature, among which molecular structural symmetry is considered a key factor. In general, molecules with higher symmetry

Experiment § Special Coating for PEEK Film With the increasing adoption of high-performance engineering plastics in advanced industries, PEEK (polyether ether ketone) has been widely used in semiconductor, aerospace, medical, and automation equipment applications due to its excellent heat resistance, mechanical strength, and dimensional stability. However, the inherently low surface energy of PEEK materials presents significant challenges in adhesion processes. GC429-1 is a

Experiment § Design Direction for Jet Valve Dispensing Products In recent years, jet valves have become a mainstream dispensing technology due to their high speed and high precision (Fig. 1). Compared with conventional needle dispensing systems, jet valves can achieve dispensing speeds more than 10 times higher and are capable of handling high-viscosity materials with high filler content. To ensure stable jetting performance, product development should focus on three key asp
