Thermal Properties
Coefficient of Thermal Expansion (CTE), α1 Coefficient of Thermal Expansion (CTE), α1 CTE α1 (alpha 1) is the slope of the Coefficient of thermal expansion in a temperature range below the Glass transition temperature (Tg). It explains how much a material will expand until it reaches Tg.	63 ppm/°C
Coefficient of Thermal Expansion (CTE), α2 Coefficient of Thermal Expansion (CTE), α2 CTE α2 (alpha 2) is the slope of the Coefficient of thermal expansion in a temperature range above the Glass transition temperature (Tg). It explains the extent to which a material will expand after it passes Tg.	118 ppm/°C
Flash Point Flash Point The flashpoint of a solvent is the lowest possible temperature at which it can vaporize to form an ignitable vapor. Flashpoint is often confused with “autoignition temperature”, which is the temperature at which a solvent ignites without an ignition source.	100 °C
Glass Transition Temperature (Tg) Glass Transition Temperature (Tg) The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding. The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.	-35.5 °C

What are typical applications for ABChimie® 6028 UV?

ABChimie® 6028 UV is a UV-curable resin designed to protect printed circuit board assemblies (PCBs) and components in demanding manufacturing environments, including:

Automotive electronics (e.g., control units, sensors)
Industrial automation (e.g., motor drives, PLCs)
Consumer electronics (e.g., smart devices, wearables)
Other high-reliability electronic assemblies

Why choose ABChimie® 6028 UV?

ABChimie® 6028 UV delivers rapid UV curing, excellent electrical insulation, thixotropic application properties, and strong adhesion to flexible substrates. It supports high-throughput manufacturing while providing durable protection for sensitive components.

What is the shelf life of ABChimie® 6028 UV?

ABChimie® 6028 UV has a shelf life of 12 months when stored at 5–30°C in tightly sealed containers. Prior to use, allow the product to equilibrate for 24 hours at 18–32°C for optimal performance.

What happens after the shelf life?

Using ABChimie® 6028 UV past its shelf life may alter viscosity, affecting uniformity and application performance. Always use an in-date product for reliable results.

What is the recommended curing method for ABChimie® 6028 UV?

ABChimie® 6028 UV is UV-curable and should be cured with a mercury lamp. The minimum UVA dose is 1000 mJ/cm² for a 1mm thickness. The LED-curable version is ABChimie® 6028 UV LED. Higher UVA doses do not negatively affect final properties.

What is the maximum thickness for ABChimie® 6028 UV?

ABChimie® 6028 UV can be applied up to 4mm due to its thixotropic properties, allowing high-thickness deposits without sagging.

What safety precautions should I take?

Use ABChimie® 6028 UV in a well-ventilated area, avoid skin and eye contact, and follow all Safety Data Sheet (SDS) guidelines. Keep away from open flames and sparks.

Can I adjust the viscosity?

ABChimie® 6028 UV can be customized for variable viscosities. Contact our team for guidance.
