Anhydride Curing of Alicyclic Epoxy Resin

Alicyclic epoxy resin is a kind of low molecular compound, which contains alicyclic epoxy group. It is not a polymer instead, but can produce a polymer with 3D structure and very excellent performance through reacting with curing agent. It boasts special performance thanks to its special structure (epoxy group is directly connected to the saturated alicyclic structure instead of being connected to the benzene ring through ether bond as bisphenol A epoxy resin).

Application of Cycloaliphatic Epoxy Resins in UV Curable Coatings/Inks

Due to increasingly stringent regulations on emission reduction, UV curing coatings are more accepted in regions such as Europe and North America. However, further development is needed in the Asia-Pacific and MEA (Middle East and Africa) regions. UV curing technology can be broadly divided into UV free radicals and UV cationic systems. Featuring excellent processing performance, UV cationic coatings have been widely applied in metal cans, coil steel and flexible packaging industries, which are mainly available in European and American markets.

Application of Epoxy Resin in 3D Printing

The rapid prototyping process of UV Laser Curing is now referred to as Stereolithography 3D printing process (abbreviated as SLA). Patented in the United States by Charles Hull in 1984, it is one of the earliest developed 3D printing technologies. Since 3D Systems of America first launched commercialized SLA in 1988, this 3D printing technology has been developing rapidly, which can automatically print out complex 3D objects that are difficult to be made by various other processing methods, representing an epoch-making significance in the field of processing technology. SLA utilizes computer-controlled UV laser to scan point by point on the photosensitive resin liquid level according to the shape of the two-dimensional cross-section and thus to cure the resin. Then the cured resin forms a two-dimensional shape. This process is repeated layer by layer to finally obtain a complete 3D object, with its quality mainly depending on the properties of the photosensitive resin.
