ABchimie 4002UV LED Cure Resin
- One-component
- Fast UV LED Curing
- Urethane Acrylate Coating
Product Description
ABChimie® 4002UV LED is a transparent resin conformal coating designed to provide mechanical and environmental protection to electronic components and assemblies. Its viscosity allows for thin build thickness (up to 1mm). ABChimie 4002UV is ideal for PCB protection.
ABChimie 4002UV LED is a urethane acrylate that exhibits excellent adhesion to various substrates, including flexible materials such as plastics. One of its advantages is that it cures rapidly under UV LED light (395 nm), has zero VOCs, and can be applied to high-speed manufacturing processes to increase productivity. ABChimmie 4002UV is in full compliance with REACH and RoHS regulations.

| Pot Life Pot Life Pot life is the amount of time it takes for the viscosity of a material to double (or quadruple for lower viscosity materials) in room temperature after a material is mixed. It is closely related to work life but it is not application dependent, less precise and more of a general indication of how fast a system is going to cure. | 12 months |

| Viscosity Viscosity Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application | 2000 mPa.s |
