Comparative Analysis Report of Tensan UV Adhesive and Other UV Adhesives

I. Introduction

UV adhesives are widely used in numerous fields such as electronics, optics, medical devices, etc., and there is a wide variety of products in the market. Tensan UV adhesive stands out among many similar products with its unique properties. This report aims to detail the characteristic differences between Tensan UV adhesive and other common UV adhesives, providing a reference for practitioners in relevant industries when choosing adhesives.

II. Comparison of Curing Speed

Tensan UV Adhesive: It adopts an advanced photoinitiator system and can rapidly undergo curing reaction under the irradiation of ultraviolet light with a specific wavelength. Generally, its curing time can be controlled between a few seconds and tens of seconds, depending on factors such as light intensity and glue coating thickness. For example, under the condition of a standard 365nm wavelength and a light intensity of 1000mW/cm², the curing time of Tensan UV adhesive with a coating thickness of 0.1mm is only 5 - 10 seconds, which can greatly improve production efficiency and is suitable for the high-speed operation requirements of automated production lines.

Other UV Adhesives: Some ordinary UV adhesives have a relatively slow curing speed and may require more than 30 seconds or even several minutes to achieve complete curing. This may lead to longer light irradiation time and equipment residence time during the production process, reducing production efficiency. Especially in large-scale production, this increase in time cost will have a significant impact on the overall production progress.

III. Comparison of Bonding Strength

Tensan UV Adhesive: It exhibits excellent bonding strength to a variety of different materials such as glass, metal, plastics, etc. Its unique formula design enables the glue to form a high-strength chemical bond after curing, and the adhesion force with the substrate is strong and durable. For example, in the bonding test of glass and metal, the tensile shear strength of Tensan UV adhesive can reach more than 20MPa, which can withstand relatively large external forces without debonding, ensuring the reliability and stability of the bonding part. It is widely used in the assembly of precision electronic devices and the fixation of optical elements where high bonding strength is required.

Other UV Adhesives: The bonding strength of some conventional UV adhesives varies. For the bonding of certain special materials, the ideal bonding effect may not be achieved, and the tensile shear strength may be only about 10 - 15MPa. Under the action of relatively large external forces or during long-term use, bonding failure problems are prone to occur, thus affecting the quality and service life of the product.

IV. Comparison of Weather Resistance

Tensan UV Adhesive: It has excellent weather resistance and can maintain its performance stability for a long time under different environmental conditions. Whether it is a tropical climate with high temperature and high humidity or a polar environment with cold and dry conditions, Tensan UV adhesive can effectively resist the erosion of factors such as ultraviolet rays, moisture, and temperature changes. Accelerated aging test results show that after being exposed to simulated outdoor environmental conditions for 1000 hours, the decrease in its bonding strength and physical properties is no more than 10%, ensuring the reliability of the product bonded with this glue during long-term use. It is suitable for application scenarios such as outdoor electronic displays and automotive parts that are exposed to complex environments for a long time.

Other UV Adhesives: Many ordinary UV adhesives have relatively poor weather resistance. Under the influence of environmental factors such as long-term ultraviolet irradiation, humidity, and temperature changes, problems such as aging, yellowing, and a decrease in bonding strength are prone to occur. For example, some low-quality UV adhesives may show obvious yellowing after several months of outdoor use, and the bonding strength may decrease by more than 30%, severely affecting the appearance and performance of the product and limiting their application in fields with high requirements for weather resistance.

V. Comparison of Flexibility

Tensan UV Adhesive: While ensuring relatively high bonding strength, it also has good flexibility. Its special polymer structure enables it to deform to a certain extent without breaking when subjected to external forces, effectively buffering and dispersing stress. This flexibility makes Tensan UV adhesive perform outstandingly in applications such as flexible electronic devices and wearable devices that require frequent bending or Withstand dynamic stress.For example, in the bonding of flexible circuit boards, it can adapt to the deformation of the circuit board during the bending process and will not cause cracking in the bonding part due to brittleness, thus ensuring the stability of electronic signal transmission.

Other UV Adhesives: Some UV adhesives have poor flexibility and show relatively high brittleness after curing. When subjected to relatively small bending or tensile stresses, cracks or even fractures are prone to occur, unable to meet the bonding requirements of flexible materials or products that need to withstand dynamic stress. This limits the application scope of such UV adhesives in some emerging fields of flexible electronics and smart wearable technologies.

VI. Comparison of Transparency

Tensan UV Adhesive: It has extremely high optical transparency, and the light transmittance in the visible light range can reach more than 95%. This enables it to minimize the scattering and loss of light in optical applications such as lens bonding and touch screen lamination, ensuring the clear and accurate imaging quality and display effect of the optical system. For example, in the assembly of high-end camera lenses, using Tensan UV adhesive can ensure the firm bonding between the lenses and will not cause obvious interference to light transmission, thus enabling the shooting of high-quality photos and videos.

Other UV Adhesives: The transparency of some UV adhesives is relatively low. There may be impurities or small bubbles generated during the curing process, resulting in a decrease in light transmittance. In optical applications, this will affect the light propagation and imaging effect. For example, in touch screen lamination, problems such as blurred display and color difference may occur, reducing the visual quality and market competitiveness of the product.

VII. Comparison of Environmental Protection

Tensan UV Adhesive: It complies with strict environmental protection standards and does not contain harmful substances such as formaldehyde and benzene volatile organic compounds (VOCs). During the curing process, almost no harmful gas emissions are generated, which is friendly to the health of operators and the environment. This conforms to the concept of modern green manufacturing and is especially suitable for industries with high environmental protection requirements such as electronics, medical care, and food packaging. It can effectively avoid environmental pollution and occupational health risks caused by the use of adhesives.

Other UV Adhesives: Some UV adhesives may contain a small amount of harmful components in their formulations, and a certain degree of VOC release will occur during the curing process. Although the content may be within the allowable range of relevant standards, long-term exposure may still pose potential hazards to the physical health of operators. Moreover, under the background of increasingly strict environmental supervision, their application scope may be restricted to a certain extent.

VIII. Conclusion

In summary, Tensan UV adhesive shows obvious advantages compared with other common UV adhesives in aspects such as curing speed, bonding strength, weather resistance, flexibility, transparency, and environmental protection. In numerous industries with high requirements for adhesive performance such as electronics, optics, medical devices, and automotive manufacturing, Tensan UV adhesive can provide strong guarantees for product quality improvement and production efficiency enhancement. It is a high-performance UV adhesive product worthy of priority consideration and wide application. However, different application scenarios may have different emphases on the performance of UV adhesives. When actually choosing adhesives, comprehensive evaluation and testing still need to be carried out according to specific product requirements and process conditions to ensure the selection of the most suitable UV adhesive product.
