Curing Agent
Divided into mercaptan curing agents and blocked epoxy curing agents. Thiol series are secondary distillation polythiol mercapto compounds, which have lower odor than conventional polythiols. It can be used in photo-curing systems to significantly improve the oxygen inhibition phenomenon under low-energy curing conditions. The closed epoxy curing agent cures quickly and has a high degree of cross-linking, which can significantly improve chemical resistance and salt spray resistance. Low-temperature cross-linking does not reduce the glass transition temperature and heat distortion temperature of epoxy resin.

Thiol series are secondary distillation polythiol mercapto compounds, which have lower odor than conventional polythiols. It can be used in photo-curing systems to significantly improve the oxygen inhibition phenomenon under low-energy curing conditions. The polymerization inhibition of oxygen is mainly due to the formation of peroxyl radicals from free radicals and oxygen in the system, which slows down the chain growth reaction. The active hydrogen in mercaptans can react with peroxyl radicals, and new mercaptans are formed after hydrogen is abstracted. The free radicals continue to participate in the addition reaction. It can significantly promote the adhesion, toughness and double bond conversion rate of the curing system. When tertiary amines are used as accelerators for epoxy curing agents, they can be quickly cured at low temperatures, enhance adhesion and tensile strength, and significantly improve heat and humidity resistance.
do you have any question?
In what industries can Thiol curing agent generally be used?
Thiol mercapto compounds are used in photocurable nail polish, photoresist, and 3D printing photosensitive resins. High film thickness can be quickly cured with low energy. It can adapt to 415nm, 365nm wavelength LED cold light sources, high-pressure mercury lamps, lasers and other conditions, and has excellent surface drying properties. It has good compatibility with the main resin and is transparent, colorless and odorless.
What are the applications of Thiol curing agent in printing inks?
In UV offset printing, gravure, roller coating and other low film thickness, low energy, fast printing process applications, it can improve the curing rate, and the coating surface is dry and non-sticky. Improve the anti-yellowing performance and enhance the adhesion performance to metal, glass and polymer materials.
If I need to cure at elevated temperatures, what products are recommended?
Our Epochal sealed epoxy curing agent has an unblocking temperature of about 80℃-200℃, which cures quickly and has a high degree of crosslinking, which can significantly improve chemical resistance and salt spray resistance. Low-temperature crosslinking does not reduce the epoxy resin glass transition temperature and heat deformation temperature.
What are the reasons that you Cannot use end mill as a drill?
The cutting surfaces on a vertical end mill bit (are for milling ) are on its sides , designed for cutting horizontally , a drill bit ( are for drilling ) cutting surface is at its tip , designed for cutting vertically downward .. you'll notice a end mill usually has a flat on the end of the bit .
