Decorative film material black technology | What is EB four resistant film?

Recently, Guangdong Dayi New Materials Co., Ltd. has vigorously launched a new film product - EB four resistant film, leading the trend of customized film materials in the era of 'wind vane'. And with a luxurious texture and long-lasting freshness, it endows the home space with a fashionable experience of high aesthetic value, achieving a new upgrade of film material's practical performance and high aesthetic value.

And all of this is mainly attributed to the leading black technology adopted by EB four resistant films - EB electron beam curing technology.

01  What is EB electron beam curing?

EB is the English abbreviation for electron beam.

EB electron beam refers to the electron beam that is accelerated by a high-voltage electric field and is an energy carrier with ultra-high energy.

EB electron beam is widely used in welding, disinfection and sterilization, and other fields. In addition, it is also commonly used in the curing field (curing refers to the transformation of coatings, inks, or adhesives from their original liquid state to a solid state). Due to its high energy, it can achieve instant curing in 5 milliseconds, with an excellent curing degree of 100%, and no harmful substances are emitted.

Meanwhile, EB electron beam curing technology was first adopted by aerospace and military units such as Boeing due to its ability to improve material properties and provide products with unparalleled physical and chemical properties; Subsequently, due to its high efficiency, environmental protection, and food contact characteristics, it was widely adopted by Packaging as a packaging material for producing liquid milk.

It is currently the most efficient, high-quality, and clean coating and curing technology known, and was first applied to various high-end fields such as aerospace and military industry, currency printing, etc.

The application of EB electron beam in membrane materials has upgraded both its appearance and performance, giving it advantages such as fingerprint resistance, scratch resistance, anti graffiti, non discoloration, thermal repair, environmental protection and health.

02 EB curing solves many problems of UV curing

Although traditional UV curing technology is widely used, there are still problems such as low penetration, incomplete curing, poor performance, and environmental friendliness during the curing process. EB electron beam curing technology perfectly solves many problems of UV curing and further upgrades the overall performance of the material.

  The traditional UV process has shortcomings

UV curing technology relies on photoinitiators to generate free radicals or cations to initiate polymerization, and all polymerization and crosslinking processes are carried out through unsaturated double bonds. Moreover, some photoinitiators remain in the cured coating after curing, posing environmental and safety issues.

                                                                                                                                                                                  The traditional water-based paint process has shortcomings

EB electron beam curing does not require photoinitiators. High energy electron beams directly and randomly generate free radicals in the reaction medium, which not only leads to the polymerization of unsaturated double bonds, but also allows the free radicals generated on the molecular chain skeleton to couple or initiate reactions. Without photoinitiators, there is no problem with the migration of initiators, which can meet the requirements of non-contact food packaging and is more safe and environmentally friendly.

UV curing is limited by the penetration of ultraviolet light, resulting in incomplete UV curing of heavily colored and thick layer materials, with many defects in the inner layer curing. When applied to home door panels, long-term use can cause yellowing and other phenomena, affecting the user experience and aesthetics.

There is no limit to the penetration of EB electron beam curing, with high electron beam energy and strong penetration ability. It can completely cure dark ink, metal ink, and thick ink layers without any quality issues of incomplete curing. It can complete 100% complete curing in 0.005 seconds. When applied to the membrane material of home door panels, there will be no yellowing or other problems, and it can achieve long-lasting and long-lasting freshness.

UV curing relies on photoinitiators to generate free radicals or cations to initiate polymerization. All polymerization and crosslinking processes are carried out through unsaturated double bonds, which makes the hardness of the coating not very high and easy to be scratched when applied in living spaces.

EB electron beam curing is the formation of a polymer three-dimensional network polymer through cross-linking reaction, which makes the coating have good chemical resistance and friction resistance, and strong hardness can easily face small frictions in daily life.

The process of UV curing generates heat and is accompanied by the production of volatile organic compounds (VOCs), which can easily cause environmental pollution.

Due to room temperature curing, the energy consumption of EB electron beam curing is 5% of that of traditional UV curing, and there is no generation of volatiles during forming, reducing environmental pollution and achieving true safety and environmental protection.

03  EB Practical Application Performance Advantages

In terms of coating performance, it has strong coverage. Indoor decoration EB coating, toxic substances are sealed inside the coating like 'cement', and the sealing performance is far better than ordinary traditional coatings; EB functional coating has strong anti graffiti, anti fouling, and non-toxic properties in children's rooms, kindergartens, classrooms, conference rooms, and educational centers; 

The coating is antibacterial, oil resistant, and chemical resistant. The kitchen is heavily oiled, and there are many people in the living room and bedroom. The EB film material is particularly suitable for use due to its oil resistant, fingerprint free, and non-toxic characteristics; Coating self repair, in some scenarios, requires the surface of the film to be resistant to burns, self repair for micro scratches, and high toughness and wear-resistant surfaces for countertops and floors.

In terms of decorative effect, the coating film is not prone to traditional coating defects such as fog, shrinkage, and orange lines; Due to the strong penetration of the electron beam, the coating solidifies completely and evenly from inside to outside, so there will be no collapse problem; In addition, the EB coating does not contain photoinitiators and there is no tendency for the film to turn yellow.

In addition, EB also has many magical effects in transforming decay:

In the traditional flat film and lamination industry, EB treatment of PET film, wood veneer, and melamine board can enhance skin feel, weather resistance, wear resistance, scratch resistance, and other characteristics, greatly increasing the use scenarios and increasing product added value.
