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 tend to pack...

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 UV-curable resin...

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 aspects: 1. Filler...
