Adhetron UV 8618 CC Solvent-Free UV Adhesive

Adhetron UV 8618 CC is a solvent-free, dual-curing UV coating compound developed to create a protective coating on both UV-accessible and shadowed areas of electronic boards. In official technical documents, the product is defined not so much as an adhesive, but as a conformal coating intended for PCB applications. Its ability to cure rapidly with UV and visible light, and to be additionally supported by heat when necessary, provides more reliable process control in complex board geometries. This structure offers a functional solution especially in electronic assembly lines where protection against environmental effects is required.

UV 8618 CC Technical Structure and Product Description

This product is a 100% solid-content, solvent-free, clear, and low-viscosity UV coating material. In the technical datasheet, the viscosity is given as 500–800 and the specific gravity as approximately 1.1. Its ability to form a flexible and tough film structure provides an important advantage in terms of coating continuity on electronic surfaces. Manufacturer information in the official document states that the Adhetron brand is offered under Pulsar Chem. Industry and Trade Co. INC.; however, the country of origin is not separately specified in the public technical document.

Adhetron UV 8618 CC Performance Features

According to the official TDS data, the product has a service temperature range of approximately -50 °C to +120 °C. In its cured state, it has a Shore D hardness of 45–60, an elongation value of 80%, and a tensile strength of 26.1 N/mm². In addition, the manufacturer particularly emphasizes that it provides good resistance to high humidity and environmental conditions. These data show that the product not only coats electronic components, but also provides a certain level of mechanical flexibility and environmental durability.

Curing Mechanism and Application Method

UV 8618 CC can be used with UV-A, visible light, and LED sources; the technical document specifies a wavelength range of 365–405 nm. In addition to light curing, thermal curing options are also given as 60 minutes at 110 °C, 30 minutes at 120 °C, or 15 minutes at 150 °C. This dual-curing structure increases process reliability in shadowed areas where light cannot directly reach. The product can be applied with pressure/time or positive displacement dispensing equipment and should be stored in its original sealed packaging at 23 °C with an approximate shelf life of 12 months; it is clearly stated that it must not be frozen.

Industrial Application Areas and Key Advantages

This coating compound is especially suitable for use in PCB manufacturing, electronic board assembly, control modules, sensor boards, LED driver circuits, telecommunication equipment, and sensitive electronic systems exposed to moisture. Its suitability for circuit designs that include both open areas accessible to UV and shadowed regions makes the product more functional for mass production. Its solvent-free structure, low viscosity, transparent option, and availability with fluorescent additive if desired provide practical advantages for quality control and coating inspection. For this reason, the product stands out as a technical conformal coating solution for applications seeking environmental protection and process continuity in electronic systems.
