At present, the domestic light-curing paint inks are mainly free radical systems.Light curing ink coatings only account for 1-3% of the global ink coatings. Free radical light curing ink coatings do not achieve the expected effect in some applications. There are still some bottlenecks that need to be broken through. Some defects need to be improved, such as too large shrinkage, poor weather resistance and high halogen content.The cationic system can compensate for these defects of the free radical system.

Materials and cationic curing resins (transparent coatings, inks, adhesives, stereolithography)Light curing technology is a kind of light processing technology that enables liquid resin to be polymerized into solid state by ultraviolet light irradiation of a certain wavelength. It saves energy, does not contain solvents, has a protective effect on the ecological environment, and does not emit toxic gas and carbon dioxide to the atmosphere. Therefore, it is known as a "green technology".

A certain proportion of alicyclic epoxy resin needs to be added to the light curing coatings and inks.

The curing speed is fast, the shrinkage rate is low, the surface is wrinkle-free, the adhesion force is strong, and the corrosion resistance is strong. It not only retains the properties of the original epoxy resin, but also greatly accelerates its curing speed, so that it cures within minutes or even seconds, greatly improving the labor productivity.

The hardened paint film and ink are obtained by light curing technology, which has the following advantages: energy saving, environmental protection, high quality and high efficiency.

Electronic encapsulation    

Electronic materials (plastic-encapsulated semiconductor, LED, bottom filler)

The alicyclic epoxy resin related products of TTA are the main resins in low halogen or even halogen-free electronic encapsulation adhesive, and can effectively improve the thermal resistance of the colloid.

In recent years, the LED industry has developed rapidly, and industry experts are generally optimistic about the market prospects. TTA21 was used by Guangzhou Huili as a representative of many packaging glue manufacturers to produce direct-plug LED packaging glue more than years ago, effectively ensuring the service life of outdoor LED display and other terminal products. With the continuous breakthrough of LED lighting technology, TTA products have a new stage that can play its own advantages.TTA21, TTA3150 and other products are used in patch LED encapsulation adhesive by companies such as Shanghai Lianlang and Shenzhen Guanggu. The high-temperature resistance of high-power encapsulation adhesive is close to that of expensive imported silica gel, and the 0.5W grade encapsulation adhesive can achieve zero optical decay in 2000 hours.

Electrical insulating materials (electrical insulating varnish, resin insulator, gas insulated combined electrical equipment)

As the heart of motor, the performance of insulation system directly affects the reliability and operation life of motor.Thermal breakdown of insulation caused by dielectric loss is a common concern of motor insulation, especially in the insulation of variable frequency motor, the degree of insulation heating is much greater than that of power frequency motor.Therefore, higher requirements are put forward for the insulation impregnated resin, which needs higher heat resistance and lower dielectric loss to ensure the safe operation of the motor insulation system.

As the raw material of impregnating resin, TTA21 series products have high performance, excellent electrical performance and low dielectric loss, and are suitable for insulation treatment of high-power traction motor coils and windings.VPI resin related data

The alicyclic epoxy resin has good heat resistance, mechanical properties and weather resistance, especially its small viscosity and long application period. It is especially suitable for wet lamination and winding forming to produce high-strength heat-resistant composite materials, and has been applied in deep-water submarines and missiles.
