High Light Sensitivity Thiophene Derivatives
PAS-20 is a thiophene structure derivative known for its excellent photosensitivity. It shows extremely high sensitivity to ultraviolet light. Even if the addition accounts for only 1 ‰ of the total, it can significantly improve the efficiency of photochemical reactions. PAS-20 not only exerts excellent sensitization effects in cationic photoinitiator systems, but also exhibits equally excellent performance in free radical systems. This versatility makes it ideal for a variety of light-initiated reactions.
PAS-20 also exhibits excellent surface drying, meaning it does not cause yellowing or unevenness during processing and preparation. In order to maximize the performance of PAS-20, it is recommended to first configure it into a 10% concentration solution and then add it. Thiophene derivatives can be used to prepare coatings and films with special properties, such as anti-corrosion coatings and optical coatings. In optical material preparation, products can be used to improve the optical properties of materials, such as transparency, reflectivity, and refractive index.
