Facing the future, Stick together, With faithfulness and sharing
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.

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.

The alicyclic epoxy resin is used in 3D printing, which has the
characteristics of low curing shrinkage, low VOC, low viscosity, nearly
colorless and transparent overall, good yellowing resistance and weather
resistance.

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.
