Experiment  § Epoxy Resin for Handicrafts In handicraft production, immersion and casting techniques can be used to create works that combine practicality with aesthetic value, such as keychains, coasters, and bookmarks (Figures 1 and 2). These differ from the craft style presented in Issue 338. In this application, a low-viscosity epoxy resin, JD052-3, was selected. When mixed with pigments, the viscosity remains below 1000 cps, providing excellent leveling properties and a

Experiment  § AT-710 Automatic Potentiometric Titrator Red adhesive (chip red adhesive) is a material used in electronic assembly processes to secure components, ensuring they remain safe through subsequent high-temperature and vibration processes. In the Surface Mount Technology (SMT) process, small components such as resistors and capacitors often have a small dollop of red adhesive underneath (Figures 1 and 2). Its function is to form a central “adhesive bump” under the co

Experiment  § Medium- and Low-Voltage Cold-Shrink Silicone Cable Insulation Components We have developed FX301-14, an electrical-grade liquid silicone rubber (LSR) for insulation applications. This product is a two-component, dark gray, paste-like, tear-resistant LSR, specifically designed for injection molding (Fig 1,2). It offers excellent resistance to yellowing, outstanding elastic recovery, superior thermal aging resistance, and ease of processing. In power system applic

Experiment  § Development of Furan Prepreg Resin Furan resins can be produced from furfuryl alcohol (FA), which is extracted from agricultural waste such as corn cobs, making them an important material in the field of sustainable and green chemistry (Figure 1–2). After polycondensation, furan resins form a cross-linked network structure. Due to the inherent stability of the furan ring, these resins exhibit excellent resistance to acids, alkalis, solvents, and heat, and are co

Experiment  § AT-710 Automatic Potentiometric Titrator Everwide has introduced an AT-710 automatic potentiometric titrator to enhance laboratory analysis efficiency and accuracy. This instrument is applied to the determination of Total Acid Number (TAN), Total Base Number (TBN), Epoxy Equivalent Weight (EEW), Hydroxyl Value (OH Value), and isocyanate group (–NCO) content (Figure 1). The AT-710 utilizes potentiometric titration for analysis. By monitoring changes in ion concen

Experiment  § Sensitizers I Have Studied With the rapid development of polymer materials in industrial and medical fields, advances in polymerization techniques have become a key driver of material innovation. Among these, ionic polymerization is characterized by high efficiency and controllability, and it is increasingly applied in the preparation of high-performance resins and precision materials. In typical ionic polymerization reactions, the wavelength range of light abso

Experiment  § Fast-Drying Screen Printing Adhesive Screen printing is a long-established and widely applied printing technique. Its core principle lies in using a mesh screen as a stencil, allowing ink to pass through the mesh and transfer onto the surface of the substrate. This technique is commonly used in textile. printing, packaging printing, as well as the printing of instrument panels and printed circuit boards. The screen itself is a critical component in the printing

Experiment  § Fluorescence enables precise adhesive release In the electronic packaging industry, UV-release adhesive tapes are commonly used as auxiliary materials. Their key feature is that upon exposure to ultraviolet (UV) light, their adhesion decreases, making it easier to remove components or substrates. A common challenge with release tapes is that after removal, small amounts of adhesive residue may remain, which are often difficult to detect with the eye and can affe
