On April 8, 2026, significant progress was made in the research of mercapto organosilicon polymers, vinyl silicone resins and their 3D printing applications. Mercapto organosilicon polymers feature high reactivity, strong adhesion, excellent flexibility and chemical stability, serving as a key component in UV‑curable systems. Vinyl silicone resins stand out for fast photocuring, low shrinkage and high crosslinking density, well suited for high‑precision 3D printing such as SLA and DLP. Through thiol‑ene click chemistry, the two components achieve highly efficient, byproduct‑free crosslinking. The cured products deliver balanced mechanical properties, weather resistance and thermal stability, suitable for flexible electronics, biomedicine, automotive gaskets, aerospace and more. The global mercaptosilane market is growing steadily. Leading firms including Gelest, Shin‑Etsu, Evonik and Wacker keep launching high‑performance products, while Chinese producers show strong advantages in scale and cost control. This system breaks through bottlenecks in strength, precision and stability of traditional 3D printing materials, accelerating the industrialization of high‑end additive manufacturing.
