FAQs
While using an EPO-TEK® product after its stated shelf life is not recommended, expiration does not necessarily mean the material is unusable. Product performance should be evaluated before use, as properties may change over time. For guidance on evaluating expired material, please refer to EPO-TEK® Tech Tip 5.
If you have additional questions, please consult our Application Experts at (978) 667-3805 or techserv@epotek.com.
For the best results, follow the product’s recommended mixing ratio, application instructions, pot life, and cure schedule. Prepare clean, dry bonding surfaces before application, and mix two-part epoxies thoroughly to ensure a consistent blend. Proper storage, handling, and curing are essential for achieving optimal bond strength and long-term performance. Please refer to EPO-TEK® Tech Tip 1 & Tech Tip 2:
If you have additional questions, please consult our Application Experts at (978) 667-3805 or techserv@epotek.com.
The minimum bond line depends on the adhesive, substrate materials, and application requirements. While a thinner bond line is often desirable, it must still provide complete surface wetting and adequate adhesive coverage. A bond line that is too thin can reduce mechanical strength, thermal or electrical performance, and overall bond reliability. Always follow the product’s technical data sheet recommendations for your specific application. Please refer to EPO-TEK® Tech Tip 6 for more questions.

To minimize bubbles and voids, mix the epoxy slowly to reduce air entrapment, apply the adhesive carefully, and allow trapped air to escape before curing when possible. Vacuum degassing, pressure curing, or gentle warming may also improve results, depending on the adhesive and application requirements. Please refer to EPO-TEK® Tech Tip 4.
If you have additional questions, please consult our Application Experts at (978) 667-380 techserv@epotek.com.
Removing cured epoxy depends on the adhesive, substrate, and application. Common methods include applying heat to soften the material, using mechanical techniques such as scraping or grinding, or using compatible chemical removers. Always select a removal method that will not damage the underlying components or bonded surfaces. Please refer to EPO-TEK® Tech Tip 8
If you have additional questions, please contact our Application Experts at (978) 667-3805 or techserv@epotek.com.
Silver-filled epoxies are generally compatible with noble metals such as gold, silver, platinum, and palladium, as well as many common electronic substrates. Compatibility depends on the substrate’s surface finish, application environment, and performance requirements. Selecting compatible metallization helps ensure reliable electrical conductivity and long-term bond performance. Please refer to EPO-TEK® Tech Tip 12
If you have additional questions, please consult our Application Experts at (978) 667-3805 or techserv@epotek.com.
Minor variations in color or appearance between epoxy batches are normal and do not necessarily indicate a change in product quality or performance. Differences in raw material lots and manufacturing processes can result in slight visual variations while still meeting established specifications and quality standards. Please refer to EPO-TEK® Tech Tip 14
If you have additional questions, please consult our Application Experts at (978) 667-3805 or techserv@epotek.com.
A suitable mold release agent prevents cured epoxy from adhering to molds and tooling, making part removal easier and reducing the risk of damage. Silicone-based, fluoropolymer, or wax-based release agents are commonly used, but compatibility with the epoxy, mold material, and application should always be verified before use. Please refer to EPO-TEK® Tech Tip 22

Glass transition temperature (Tg) is the temperature at which a cured epoxy changes from a rigid, glass-like state to a softer, more flexible state. Understanding Tg is important because it affects an adhesive’s mechanical strength, thermal stability, and long-term performance, particularly in applications exposed to elevated temperatures. Please refer to EPO-TEK® Tech Tip 23

Yes – please contact our Application Experts to discuss options: (978) 667-3805.
Yes, but we choose products by application first in addition to matching performance properties stated on competitors’ data sheets.
Please consult our Application Experts at (978) 667-3805 or techserv@epotek.com to discuss your specific requirements.
The main difference between the 2.5 W/mK and 29 W/mK thermal conductivity values listed on the data sheet for EPO-TEK® H20E is test method. The first value of 2.5 W/mK wa: measured using our standard laser flash test equipment, in accordance with ASTM E1461.
This involves using a disk of material that is approximately 12.55mm in diameter and 1mm in thickness. It provides a bulk property and does not reflect the actual performance of the material in a given assembly. The second value, 29 W/mK, reflects actual measured circuit value from a power 1u-ls device. This was back calculated using the thermal resistance determined in the device with a 2mm x 2mm chip and a 75um bond line.

It may be settling of the filler which can be a common phenomenon. Most of the time, the filler can be incorporated back in with some gentle mixing. It is good practice to stir a filled system before each use to ensure the filler is evenly dispersed within the epoxy matrix before using. A method for preventing this filler settling is to store the closed epoxy container on a jar roller to keep the material evenly suspended within the system.

Yes. Most epoxies have a Poisson’s ratio between 0.30 and 0.35, with 0.30 commonly used as a general value for FEA modeling. Actual properties may vary by material and application.
