In the field of photocurable materials, oxygen inhibition has long plagued the performance improvement of industries such as coatings, inks, and nail polish. Oxygen molecules react with free radicals, hindering the complete completion of the polymerization reaction, causing the surface of the material to become sticky and the curing efficiency to decrease. Thiol-30L Oxygen Inhibition Resistant Thiol (anti-oxygen inhibition polymer thiol) launched by Shenzhen U-Sunny has successfully broken through this technical bottleneck through innovative molecular design and process optimization, providing efficient and environmentally friendly solutions for the chemical industry.
1. Principle of Thiol-30L's Anti-Oxygen Inhibition Technology
Thiol-30L is a highly active thiol compound based on thiol (-SH). Its unique molecular structure can significantly reduce the interference of oxygen on free radical polymerization. In traditional photocuring systems, oxygen will combine with active free radicals to generate peroxides, terminating the chain growth reaction; while Thiol-30L achieves anti-oxygen inhibition through the following mechanisms:
Fast chain transfer: The high reactivity of thiol makes free radicals react with thiols first, shortening the life of free radicals and reducing the contact time with oxygen;
Synergistic curing path: The thiol-ene click chemistry and free radical polymerization dual paths work together to reduce sensitivity to oxygen, and deep curing can be achieved even in thin layers or high oxygen environments;
Low odor and high purity: refined through secondary distillation process, VOC content is less than 0.5%, in line with EU REACH and US UL environmental certification, suitable for indoor scenes.
2. Multi-field application and performance breakthrough
1. High-performance coatings and inks
In UV coatings, Thiol-30L as a crosslinker can increase the curing speed by 30%, the surface hardness reaches more than 3H, and the surface sticky residue is reduced by 60%. In the field of inks, its compatibility with water-based resins optimizes printing adhesion and is suitable for safety-sensitive scenarios such as food packaging.
2. Fast-curing adhesives
Through the thiol-ene reaction, Thiol-30L achieves adhesive curing in seconds, and the bonding strength is 50% higher than that of traditional epoxy resins. Its weather resistance can withstand a temperature difference of -40℃ to 120℃, meeting the stringent requirements of automotive electronics and medical equipment.
3. Innovative application of nail polish
Nail polish requires extremely high oxygen inhibition performance because it needs to take into account both fast curing and low irritation. The addition of Thiol-30L increases the efficiency of UV curing by 40% and reduces odor emissions by 90%. Combined with anti-settling technology (such as fumed silica), the life of the manicure can be extended to more than 21 days.
3. Shenzhen U-Sunny's technical advantages and quality assurance
Shenzhen U-Sunny relies on the ISO 9001 system and uses a secondary distillation process to ensure the purity of Thiol-30L, and precisely control the molecular weight distribution to avoid impurities interfering with terminal performance.
