1. Cationic UV/Thermal Curing Coatings:
As a crosslinking monomer and reactive diluent, it reduces the viscosity of the coating system and increases crosslinking density. The cured coating exhibits excellent chemical resistance, weather resistance, and adhesion, making it suitable for industrial protection and decoration of substrates such as metals, plastics, and wood, especially for coating systems requiring high weather resistance and low yellowing.
2. Electronic Materials and PCB Manufacturing:
Used in PCB solder mask inks, electronic component encapsulation materials, and insulating coatings, its low viscosity improves processing performance. The cured material has stable dielectric properties and excellent insulation, ensuring the stable operation of electronic devices in complex environments such as high humidity, high temperature, and low temperature, making it suitable for microelectronic packaging and precision processing of circuit boards.
3. Optical Material Preparation:
Applied in optical films and optical adhesives, it reduces curing volume shrinkage, improving the dimensional stability and light transmittance of optical components, meeting the high precision and high transparency requirements of optical lenses and display devices.
4. Ink Industry:
As a reactive diluent for UV-curing inks, it reduces ink viscosity to suit processes such as screen printing and flexographic printing. The cured ink film has good wear resistance and weather resistance, suitable for packaging printing and other applications.
5. Adhesives and Sealants:
Used in the preparation of cationic curing adhesives and sealants, it improves product fluidity and enhances the bonding strength and sealing effect on various substrates such as metals, ceramics, and engineering plastics, suitable for bonding and sealing of industrial components.
6. Resin Modification and Synthesis:
Used as a modifying monomer in the synthesis and modification of epoxy resins, polyester resins, etc., it reduces system viscosity and improves the flexibility, weather resistance, and chemical resistance of the cured product, suitable for the development of resin systems with high performance requirements.
7. Composite Material Matrix Resins:
Compounded with other cationic curing resins, it is used to prepare high-performance composite materials, improving the mechanical strength, aging resistance, and processing fluidity of the material, suitable for the preparation of structural components with stringent requirements on overall material performance in aerospace and automotive manufacturing.
