  • CURABLE COMPOSITION
    Publication number: 20240117084
    Abstract: A curable composition is provided. The curable composition can eliminate or minimize the generation of bubbles inside the cured product after the initiation reaction of the curable monomer, prevent expansion of a material when used to encapsulate a device, and provide a uniform cured product to solve the problem of separation between the upper and lower substrates bonded together, thereby improving device encapsulation performance.
